FORWARD
Following the tradition of Asterisk@Home without Tears and Trixbox without Tears, this
guide is not meant to be a detailed manual for Trixbox®; instead it is just a quick and dirty
guide and a resource to assist you get started with minimum pain. As always, use this
document only as a guide, not as a Gospel. It does not cover every detail in Trixbox
neither will it provide you with a complete solution or spiritual guidance.

Only a competent VoIP consultant can provide you the necessary know-how for a
complete solution, and as for spiritual guidance, I will leave that to you.

This document was compiled mainly based through my experience going through the
wash, supplemented by inputs from dozens of participants in the Whirlpool and other
Trixbox and Asterisk related forums. These people were mentioned in A@H and Trixbox
without tears. They have helped me whenever I get into difficulties, and I still seek
guidance (the Trixbox/Asterisk type) from them.

I take no primary credit for this document (I am only the compiler of the not so divine
revelation). I invite others to participate in improving this document. Please send me your
feedbacks; so together we can make this document a valuable resource for our peers in
the Trixbox community, experienced and new alike.

- Ben Sharif January 1, 2007.

The usual disclaimer: (Don’t you just hate it, having to say this.)
In its Basic form, all that I have outlined worked for me but it may contain many
errors – typographical, omissions and even misguidance that may require a lot of
extra corrections. While I have taken due care, however, it may not necessarily be
suitable for your individual configuration. I do not take; neither will I accept any
responsibility for any losses incurred due to actions or inaction conducted as a result
of methods or advice found in this document.

I do not provide Trixbox support and neither do DIGIUM. If assistance is

required, please post in the forum. Participants in the various forums may
have a number of solutions and at the same time providing the opportunity for
others with similar questions to benefit from the solutions provided.

Ever since the release of A@H without Tears, I have received numerous emails asking
for assistance. Since I am putting a lot of efforts into providing personal assistance to
those who have sent me donations (incidentally, my only source of income), the volume
of email I received has become unmanageable. While I will try to assist within my limited
knowledge, I hope you will understand if I don’t answer each and every email.

I am not an expert and therefore I do not have all the answers. I ask those
requiring assistance to post their questions in the Whirlpool, Digium, freePBX
or Trixbox Forum (forum participants may not answer any question if the
solution is already in this guide) where there are many knowledgeable
Asterisk and Linux savvy participants who will be able to assist.

1 INTRODUCTION
Asterisk© is a Linux based IPBX application developed by Mark Spencer of Digium™, the
company behind Asterisk. Trixbox© evolved from the core Asterisk. It is made up of
several major components. These were developed under GPL supported relatively by
users themselves. It consists of applications, a provisioning system, an installer, and an
operating system that, together, make a complete package ready for use as an out of the
box PBX.

Within this document, Trixbox© and Asterisk will be referred to frequently and they are
interchangeable as Trixbox© is in essence a superset of the Asterisk.

1.1 Is VoIP for you?

Whether VOIP is for you or not depends on a number of or combinations of factors.
Some economic and quality requirements should be considered.

1.1.1 What is it going to cost?

Assuming that you already have a broadband service, a router, and a Windows PC to
run the softphone, the cost will be minimal.

If you already have a spare computer to dedicate to this task, then the cost is almost
nothing unless you need to buy an audio headset ($15.00 from your local electronic
store) for the softphone. If you do not have a spare PC with the above specification,
then you may be able to buy one from your local swap meets for under $200.00,
which may include a monitor. Ensure that the PC has an Ethernet NIC for connecting
to your home network.

Your only other initial cost will be the $20.00 or so activation fee to Oztell (or other
VSP of your choice). In fact many VSPs, the like of Pennytel, Primus etc., will
register you for free if you want to restrict your calls to VoIP only within the same
VSPs. If you want the ability to make to PSTN or between different VSPs, you may
have to pay for the calls.

All these “Major Expenses” will be recovered when you receive your monthly Telstra
or Optus phone bills.

1.1.2 What will the quality of the phone calls be?

If you are expecting the quality to be consistently as good as your existing PSTN
calls, you will be somewhat disappointed, but if you will be happy with a quality that is
comparable to your mobile phone, not quite but close to your existing PSTN calls and
also be prepared for the whining by the other half, the phone calls are not being as
good, while you are leaching off the P2P, you might be in luck.

VoIP via the Public Internet is very much dependant on a number of factors –
available bandwidth not withstanding, your usage habit of the internet and LAN traffic
and equipment quality, amongst others, also play very important roles.

1.2 What is Trixbox?

Trixbox is a collection of telecommunication utilities and tools compiled together to
become an integrated IP PBX. The major components that make up Trixbox© are;

TRIXBOX-2 Without Tears Page 11 of 224

 • Asterisk, the core PBX
• Sugar, a CRM system
• A2Billing – Calling Card platform
• Flash Operator Panel, a screen-based operator’s console
• Web Meet Me Control, a meet me conferencing control application
• freePBX a web-based User Interface tool for Trixbox.
• A report system – the part of freePBX that provides CDR reporting.
• A Maintenance system, also part of Trixbox©, which provides low level interfaces
to some components and real time system information
• CentOS, a version of Linux related to a very well known Enterprise Linux (but
without the branding and support).

1.3 The IP PBX Components

Four main components needed to set up VoIP PBX:

• Trixbox, the Asterisk powered IP PBX

• The phones (or softphones)
• The VOIP gateway services that let you call other VOIP users and people on the
PSTN.
• Have a home network and broadband access with a router and hubs/switches if
needed. If you are restricting the usage to PSTN only, you will not need the
broadband, but then it will defeat the whole purpose.

Trixbox-2 while essentially similar to the previous version 1.x, does consist some set-up
differences that warrant explanation. I will attempt to describe the set-up of each of
these. In most cases it does not matter if you are behind a firewall provided that you have
all the appropriate ports forwarded correctly. You are not required to do anything special
like running the IP PBX outside the NAT or in the DMZ. However, it is important to
ensure that you have enough bandwidth (upstream and downstream) to carry voice
traffic.

1.3.1 The IP PBX

You will need a computer to run the IP PBX. It is recommended that you run a
dedicated PC for this purpose. The PC described below (minimum) will be sufficient
to power the IP PBX in a small office or home environment. Therefore don’t throw
away that old Pentium II clunker you have in the attic.

• 350Mhz Pentium II PC or better (PIII 800 will give extra comfort).

• 256MB RAM – the more the better
• 4 GB Hard disk space - minimum.
• 10/100 NIC
• CD-ROM Drive
• 10/100 4 or 8 ports Ethernet hub/switch (not required if your router has spare
ports)

If you are using Telstra Alcatel SpeedTouch 510/530 ADSL Router, you will need
to unbind port 5060. To do this, please refer to this link (or see Appendix D).
http://www.sipgate.co.uk/faq/index.php?aktion=artikel&type=faq&rubrik=024&id=398&lang=de

When you install Trixbox© on this “old” computer, it will take it over – it starts by
formatting all the hard disks (if you happen to have more than one), so make sure
there is nothing on the machine that you want to keep. Detailed instructions are
given in the installation section.

TRIXBOX-2 Without Tears Page 12 of 224

 1.3.2 Phones
You can buy SIP phones from Grandstream, SNOM, and Cisco etc. Or you can buy
an ATA (Analogue Telephone Adapter) produced by Linksys, Netcomm or Sipura and
a few others, which enables you to use an analogue phone (the Linksys PAP2 will
allow you to hang two analogue phones to it). The Netcomm and Linksys ATAs can
be bought from Harris Technology and a number of VSPs.

Register with a VSP such as Faktortel, Oztell, Pennytel and several other VOIP
Service Providers (VSPs) or you may buy Engin locked ATAs from Harvey Norman
and Dick Smith Electronic. The choice is yours.

To get started, it is easiest to get a softphone and run it on another computer. See
the section on installation of Softphone later in this document.

1.3.3 SIP Gateway

It is most likely that you want to communicate with others on the PSTN network, so
you need to obtain a VOIP gateway service. Since part of the call is being carried on
the circuit switched network, it costs real money. This means that you will have to
pay for this part of the system.

Setting up gateways will be covered in the installation section below.

1.3.4 Home Network

The fact that you are reading this and contemplating on installing Trixbox© , I assume
that you have a home network, a broadband service, and are set up behind a Router
of some sort.

You will need to pick a static IP address for your IP PBX that is on your home network
e.g. 192.168.0.100. To keep it simple, please ensure that the Asterisk box is in the
same network segment of your existing LAN.

1.3.5 VOIP Service Providers

If you are in Australia, the Whirlpool VOIP forum has a list of VOIP providers in
Australia at the following link: http://forums.whirlpool.net.au/forum-replies.cfm?t=370536

2 INITIAL PREPARATION AND PLANNING
Before setting up your IP PBX, it is recommended that you map out what your home (or
small office) telephony requirements are.

Compare the requirements with what facility you already have. You may find that you
may need to provide extra facilities that you do not already have e.g. Network switches,
router, ATAs or IP Phones and needless to say a suitable broadband service.

For the purpose of this guide, I have determined that we will start with the following:

• 2 extensions with voicemail using a Linksys PAP2 ATA

• 1 extension using a Linksys SPA3000 ATA
• 2 extension using Softphone (we will use these 2 extension for initial testing)
• 3 extension using IP Phones
• 2 VoIP service providers
• 2 PSTN trunks – for the purpose of this exercise, I will be using a Linksys
SPA3000 for one PSTN trunk and a X100P for the other PSTN trunk.
• IVR
• Music on hold
• A number of customised voice prompts and announcements

Once the above are set-up, I will customise it further with the following;

• Time conditions
• Ring groups
• Follow me
• Conference facility
• DISA
• Etc.

In this exercise we will cover all of the above (not necessarily in the stated sequence) and
we may also look at other possibilities as we go along, if time and/or resources permit.

This is not an industrial grade installation. This installation is for taining

purposes only and to assist new hopefull to get started with Trixbox and nothing
more.

Once you are clear on what you want, you can start the installation in earnest.

TRIXBOX-2 Without Tears Page 14 of 224

3 INSTALLATION
A PC is a prerequisite. You can either install Trixbox© in a virtual machine in your
Windows based PC (there is a version of Trixbox© for this) or install Trixbox© on a
dedicated PC. The later is recommended given that once it is set-up, we will need to
leave the PC running and not burden it with other daily applications such as playing
games, browsing the internet or doing the children school assignments.

For stability, I will suggest that Trixbox© be installed on a dedicated machine. This is
what we are setting out to do.

3.1 Initial Installation

The Trixbox© version that we will be installing is the latest current version available today
– Trixbox© 2.0. You will need to download the ISO from the Trixbox© website below.
http://www.trixbox.org/modules/smartsection/item.php?itemid=2/

After you have completed the download,

• Burn the ISO image that you have just downloaded to a blank CD.

• Ensure that your PC will boot from the CD. If necessary change the BIOS
settings to enabled this.

• **NOTE: This will erase all data on the hard drives of the PC.
If you have 2 drives, both may be blown away as well - beware.

• Boot your Trixbox PC with the CD in the CD Drive and press enter. After a few
seconds, the following screen will be displayed. You press F2 to see the various
options. However, it is not really necessary. Just press [Enter] to start the
installation

• Press the Enter key to start the installation.

TRIXBOX-2 Without Tears Page 15 of 224

 • After initial system detection, you will be asked to select the type of keyboard that
you will be using. Use your cursor keys to navigate the keyboard types and use
the Tab key to move the focus to the OK or Back option. Select the appropriate
keyboard. Selected us and move the focus to OK and hit [Enter]

• After system hardware probing is completed, you will be asked to select the Time
Zone you are in.

• Use your cursor arrow keys to navigate to the appropriate time zone. In our case,
we will selected Australia/NSW. Use the TAB key to move the focus to OK and
hit [Enter] to accept.

• Next you will be asked to enter your root password (remember this password).

TRIXBOX-2 Without Tears Page 16 of 224

 • After entering and confirming your password, installation will now commence by
first formatting the Hard Disk/s.

• From this point it will take about 30-45 minutes for the installation to be complete
and ready for the configuration stage.

• During this stage, you will see screens similar to the following. Linux and the
required files are being installed. All you do is, wait for it to finish.

• After Linux is loaded the CD will eject. Take the CD out and wait for the system to
reboot.

• When it reboots, you will be presented with the following screen.

TRIXBOX-2 Without Tears Page 17 of 224

 • After a moment, it will continue and you will see lots of lines of codes. This
process will take a while because it is building Asterisk.

• When Asterisk build is complete, it will reboot itself. Once rebooted, Trixbox© is
ready for you to continue configuring and make changes to the system default.

3.2 Change Default Settings

Once Trixbox© has been installed, some changes need to be made to secure your
installation.

Log in to your new Trixbox© (user: root, password: The one you gave earlier)

Trixbox 2.0 uses freePBX 2.1.3. To take full advantage of the latest freePBX
features, lets upgrade the existing freePBX to the latest version 2.2. See the section
on upgrading freePBX. Once that is done we will come back here.

TRIXBOX-2 Without Tears Page 18 of 224

 3.2.1 To get Help

At the command line, type

help-trixbox

A list of help will be displayed – see illustration below:

The help screen will also tell you the necessary command required to
change the password of the various default users e.g. passwd-maint for
user maint and passwd for user root.

3.2.2 Change IP Address (set IP address to Static)

Change Asterisk IP address from DHCP to Static. At the command prompt enter:

netconfig

Select [Yes] to set up networking and hit enter.

TRIXBOX-2 Without Tears Page 19 of 224

 You will then see the following screen.

Use the Tab key to cycle through the fields. Enter the IP address that is to be
allocated to the Asterisk box, the Netmask (subnet mask), Default Gateway, and
Primary nameserve as per the example above. In my example above, I used my
existing network regime.

• In the IP address field, enter an IP address Trixbox© making sure it is within

your network range e.g.: 192.168.1.100
• Netmask is normally 255.255.255.0 unless your network has different Network
mask.
• Default gateway IP is the address of your router. In my case, my router address
is 192.168.1.1
• Primary nameserver is the address of your Name Server, usually your domain
server if you have a network domainserver but if you are running workgroup, use
the address of your default gateway e.g.: 192.168.1.1

Once done, select OK.

Those are the initial inputs that require immediate attention. Others, such as Admin
password etc, are optional although it is recommended that you change them. Once
done, log off Linux and reboot.

amportal stop
Shutdown –r now

Asterisk will now start with the new IP address.

TRIXBOX-2 Without Tears Page 20 of 224

4 SET-UP TRIXBOX
Now, using your browser, you can connect to http://ipaddress/ (e.g. http:192.168.1.100)
to configure Trixbox© .

You will be presented with the Trixbox© initial User Mode splash screen as illustrated
below.

This screen (once Trixbox© has been properly set-up) enables users to monitors ARI,
FOP (flash operator panel), Client Manager (SugarCRM) and setup personal MeetMe
requirement.

As it stands, Trixbox© need to be configured before any of those facilities are operable by
users.

Initial Welcome Screen (User Mode)

To start configuring Trixbox©, it is necessary to switch to Admin Mode. To do this, click

on the “switch” label situated on the top right hand corner of the screen (marked with an
arrow in the illustration above).

A username and password dialog screen will appear where the default username and
password need to be entered as per the illustration below.

The Username is maint and the default password is password, unless you have
changed the default password for user maint to something else using the passwd-maint
command in chapter 3.2 above.

TRIXBOX-2 Without Tears Page 21 of 224

 Log in to System Administration

To log in to System Administration, use user: maint, password: password unless you
have changed the user maint password during initial set up in 3.2

Once you logged in, you will be presented with the following screen,

Admin Mode Configuration Screen

TRIXBOX-2 Without Tears Page 22 of 224

 4.1 Installing Trixbox Modules
To install the Trixbox modules, you will need to log on to the Package Manager site to
enable you to get a list of all the available modules (see Unable to log to Packages).

I am already registered to the site and therefore I simply need to enter my username and
password to login otherwise registration will be required before one can log on to the
Package Manager site.

If you are new, click on the “Register” button and register. Simply follow the prompt.
However if you are unable to register through this method (some Firefox users are having
this problem – Ed Note. Since the new interface, neither Firefox nor IE is able to register
this way), you will need to go to http://www.trixbox.org and register to be a member of the
forum.

It is this username and password that you that is required for you to successully log in to
Packages database (Please don’t ask me why this is so).

Once logged in, select/click on the “Packages” tab (marked with an arrow above) and the
current package list will be downloaded as illustrated below.

Most of the modules necessary to get Trixbox© operational are already pre-installed and
ready for the individual administrator to start setting-up. However there are other optional
modules that can be installed if necessary, MySqlManager, tbm-phpmyadmin.noarch
is one such example. Without this package you will not be able to get to phpadmin
through the GUI.

TRIXBOX-2 Without Tears Page 23 of 224

 For this installation, we will simply use the standard default modules and for the purpose
of the exercise, we will additionally install “webmin” using the module manager.

To find the package, you may need to scroll down the list till you get to the package called
“webmin noarch” adjacent to Trixbox update as per the illustration below and place a tick
in the update box.

Click the upgrade button and webmin will be installed.

You will now have to wait for the installation to finish, as there is no progress
indicator during the process. Patience is a virtue.

How long you will need to wait depends on the number of modules that you selected. If
you only select one module, it may only take a minute or so. If you selected to more
modules it will take much longer. Once done, we can focus on the rest of the chores.

You are now ready to take the next step of installing freePBX modules as without these
you will not have the GUI interface for managing Trixbox. There are other GUI interface
that can be used but freePBX comes with Trixbox.

Before you proceed further, it is a good idea to upgrade to the latest freePBX because
by the time you install Trixbox, there is a good chance that there is a new version of
freePBX. Besides, Trixbox did not come with the latest version of freePBX.

To upgrade freePBX, go to the chapter relating to Upgrading freePBX.

TRIXBOX-2 Without Tears Page 24 of 224

 4.2 Installing freePBX Modules
FreePBX is the GUI interface that Trixbox© uses to manage the IP PBX.

Before you can use freePBX you need to install all the modules that you require. You
need to do this through freePBX.

On the Trixbox Admin Mode screen, hover the mouse pointer over the Asterisk tab and
select FreePBX from the dropdown list as illustrated below (see arrow).

The following screen will appear. Notice that only Welcome is shown on the left side of
the screen.

We are now in freePBX and this is where most of your configurations will take place.

Click on the Tools tab and a screen similar to the following screen will appear, then select
the “Module Admin” selection on the left.

TRIXBOX-2 Without Tears Page 25 of 224

 The next screen will then be presented with the list of available freePBX modules. Most
of them will not be installed.

It is up to you to select whichever modules you require to be installed in freePBX.

If the red bar as displayed above appears, simply ignore it for now.

Start selecting all the modules that you want to install. To make it simple, let's install all
the modules to start with (you can always remove modules or choose to disable some of
the modules that you do not need at a later stage).

TRIXBOX-2 Without Tears Page 26 of 224

 You don’t have to select all the modules. Only select the modules that you need.

Click 'Process' at the bottom of the list of modules once you have selected all of the
modules.

On the confirmation page, click 'Confirm.' You should get a page telling us that all
modules were installed successfully.

See the red bar at the top of the page that says 'Apply Configuration Changes’? To
confirm your intention, click on it and then click 'OK' on the window that pops up. This
reloads the Asterisk configuration and the red bar will then go away.

We will need to click on the red bar anytime you make changes

Before you go any further, you will check for modules updates that may be available or
you may wish to include other extra modules that have been released since the
installation of freePBX, online.

We will go back to the Module Admin screen and lick on the “Check for update online”
label as illustrated below.

If there are updates that you need, simply select the necessary updated modules
indicated in the list, click “Download and upgrade” radio button.

You can also uninstall or disable any module using this modular approach..

See illustration below.

TRIXBOX-2 Without Tears Page 27 of 224

 Once you have selected all the modules that we want to upgrade, click on the “Process”
button.

A list of all the modules that we have selected for updating will be displayed similar to the
screen below.

Click on the confirm button and freePBX will start the updating process.

During the updating process, freePBX will inform you of the progress of the update by
displaying the status of the modules being updated as per the illustration below.

TRIXBOX-2 Without Tears Page 28 of 224

 On completion, a red bar at the top of the page that says 'Apply Configuration Changes?’
will appear. Now click on it to confirm your intention then click 'OK' on the window that
pops up. This reloads the Asterisk configuration and the red bar will then go away.

The screen will refresh and display the following screen.

You can now click on ‘Setup’ tab next to the “Tools” tab to get to the modules you have
just activated and finally start to configure the Trixbox© IP PBX.

TRIXBOX-2 Without Tears Page 29 of 224

5 BASIC CONFIGURATION USING FREEPBX
From now on, we will be configuring Trixbox© using freePBX web GUI as this is where
most of the actions will be.

5.1 General Settings

The first thing you will need to do is select General Setting and set it up as illustrated
below. It is self-explanatory so I will not try to explain, as it is quite minimal and nothing
substantial that warrants explanation.

Notice that the extra information that will define the way Asterisk behave, are also
required in freePBX. Set the fields to the following (these are vital settings):

TRIXBOX-2 Without Tears Page 30 of 224

 Asterisk Outbound Dial command option:
“r” which generate the ring when you dial out, or “m” if you want music instead. There
are other options of course – refer to the sub-chapter on Dial Command Options.

Voicemail:
Change the Direct Dial to Voicemail message type to something other than default - this
will save you a lot of head scratching later on when you start using follow me etc. as your
customs recorded message will not be played, instead the default Asterisk message will
be played back if you don’t change the setting.

I have set mine to Unavailable.

Country Indications: Australia

Allow Anonymous Inbound SIP Calls? Yes (if this is set you ‘No’, all inbound unidentified
SIP calls will not be accepted).

Generally the default values are sufficient to get you started. These values can be
changed later to suit your purposes. However the value I have as example above is
required to ensure that Trixbox© will function as expected – at the very list, during the
testing stages.

Naturally, help is available. Hovering your mouse on the corresponding field description
with a dotted underline (e.g. Asterisk Outbound Dial Command options) will display the
purpose of the fields and the various switches related to it.

See illustration below.

After setting up the General Settings, click on Submit Changes button and the red bar on
top of the screen for the change to take effect.

5.1.1 Dial Command Options

In the Asterisk Dial command option, you may customise your preference to the
way asterisk behave e.g. if you want the caller to hear music instead of the standard

TRIXBOX-2 Without Tears Page 31 of 224

 ringing sound, you may replace the “r” with an “m”. For further options, hover your
mouse on the label and you will be informed of the other options.

The following are the dial command options available to you but for now, lets leave it
alone:

Options:

Play an announcement to the called party, using 'x' as

A(x)
the file
C Reset the CDR for this call
Allow the calling user to dial a 1 digit extension while
waiting for a call to be answered. Exit to that extension
d
if it exists in the current context, or the context defined
in the EXITCONTEXT variable, if it exists.
Send the specified DTMF strings *after* the called party
has answered, but before the call gets bridged. The
D([called][:calling]) 'called' DTMF string is sent to the called party, and the
'calling' DTMF string is sent to the calling party. Both
parameters can be used alone.
Force the callerid of the *calling* channel to be set as
the extension associated with the channel using a
f dialplan 'hint'. For example, some PSTNs do not allow
CallerID to be set to anything other than the number
assigned to the caller.
Proceed with dialplan execution at the current
g
extension if the destination channel hangs up
If the call is answered, transfer both parties to the
specified priority. Optionally, an extension, or extension
G(context^exten^pri)
and context may be specified. Otherwise, the current
extension is used.
Allow the called party to hang up by sending the '*'
h
DTMF digit.
Allow the calling party to hang up by hitting the '*'
H
DTMF digit.
Jump to priority n+101 if all of the requested channels
i
were busy.
Limit the call to 'x' ms. Play a warning when 'y' ms are
left. Repeat the warning every 'z' ms. The following
special variables can be used with this option:
• LIMIT_PLAYAUDIO_CALLER yes|no
(default yes) - Play sounds to the caller.
• LIMIT_PLAYAUDIO_CALLEE yes|no -
Play sounds to the callee.
L(x[:y][:z])
• LIMIT_TIMEOUT_FILE File to play when
time is up.
• LIMIT_CONNECT_FILE File to play when
call begins.
• LIMIT_WARNING_FILE File to play as
warning if 'y' is defined. The default is to
say the time remaining.
Provide hold music to the calling party until a
m([class]) requested channel answers. A specific MusicOnHold
class can be specified.
Execute the Macro for the *called* channel before
connecting to the calling channel. Arguments can be.
M(x[^arg]) specified to the Macro using '^' as a delimiter. The
Macro can set the variable MACRO_RESULT to
specify the following actions after the Macro is finished

 executing

• ABORT Hangup both legs of the call.

• CONGESTION Behave as if line
congestion was encountered.
• BUSY Behave as if a busy signal was
encountered. This will also have the
application jump to priority n+101 if the 'j'
option is set.
• CONTINUE Hangup the called party and
allow the calling party to continue dialplan
execution at the next priority.
• GOTO:<context>^<exten>^<priority> -
Transfer the call to the specified priority.
Optionally, an extension, or extension and

TRIXBOX-2 Without Tears Page 33 of 224

 5.2 Extensions
The number of extensions to be set up depends on you. You can have soft phones
installed in 4 or 5 computers or mixture of ATAs and SIP SoftPhones. In this case, we
have 8 extensions to be set up using ATA as well as softphone and IP phone as we have
planned.

It’s best to avoid the following extension numbers:

200 - Park Notify

300-399 - Reserved for speed dial (Backward compatible)
666 - Reserved for FAX testing
70-79 - Reserved for calls on hold (Definable)
700-799 - Reserved for calls on hold (Definable)
7777 - Reserved extension for incoming calls simulation

5.2.1 Create Extensions

To create extensions, select the type of trunk e.g. SIP, IAX2, ZAP or Custom, is done
from the Create Extension menu illustrated below:

We need to create a few SIP extensons. Therefore you should select Generic SIP
Device from the device drop-down list then click “Submit”.

The illustration below is where you create the extension.

You will notice a few fields that you will need to populate. The important ones are:

• User Extension: 2000 (that’s the extension number I gave for reception)
• Secret: 2000 (for simplicity, I used the exten number as the secret password)

I left the rest of the fields at their default values.

Submit when done.

TRIXBOX-2 Without Tears Page 34 of 224

 Add Extension Screen

TRIXBOX-2 Without Tears Page 35 of 224

 Click on the red bar on the top of the screen after every time you have submitted a
new extension.

Click on the Add Extension button to add more extensions.

We will create 8 extensions;

2000 - Main Reception

2001 - Medical Centre Manager
2002 - Dr. Stan Roberts
2003 - Dr. Susan Forbes
2004 - Dr. Francis Wong
2005 - Admin Office
2006 - Lab and X-Ray
2007 - Courtsy Phone.

For simplicity, we will allocate passwords to be the same as the extension numbers.
Where Voicemail is enabled, we will allocate the same password as well (but you
don’t have to. You may also nominate an email address for Voicemail Email
Notification – it’s up to you). Voicemail will be covered in more detail a little later in
this document.

If you want this extension to be a remote extension, you will need to edit the
extension and ensure that the entry under Device options reads Nat: yes.

5.2.2 Enable Voicemail

To enable voicemail on an extension simply "enable" it when you create the

extensions from the freePBX GUI. If you require email notification of your voicemail,
you may enter your email address in the email address field.

In this case let us enable voicemail on extension 2001 (the Manager’s extension).

Go back to the Extension Option of freePBX and click on extension 2001. Scroll
down to the Voicemail and directory section and do the following:

TRIXBOX-2 Without Tears Page 36 of 224

 • Status: Enabled (use the drop down selection to select it)
• Voicemail password: 2001 (to keep it simple we shall use the extension
number)
• Email address: Enter an email address of the person (only if you want email
notification)
• Email attachment: yes (mark the radio button)
• Play CID: yes
• Play envelope: yes
• Vm context: default

Click submit when done followed by the red bar on top of the scree.

TRIXBOX-2 Without Tears Page 37 of 224

 5.3 Follow Me
After setting up the extensions, you need to decide if you want Asterisk to call another
pre-arranged extension, if the extensions called do not answer. This is where we will
define it as per the illustrations below:

To do this, select the Follow me option; Setup -> Follow Me.

You will be presented with the following screen:

.
Select the extensions that you want to define (the extension selection is on the right of the
screen). In this case, we will pick the Medical Centre Manager’s extension – ‘Manager
<2001> add’

In the screen that follows (see the illustration above), enter the following information.

TRIXBOX-2 Without Tears Page 38 of 224

 • Ring strategy: hunt (to call the numbers in sequence)
• Extension List: 2001 (Manager’s extension) followed by Administration’s Office
and the Reception (The reception will take down messages for the Manager).
• Ring time: 40 seconds
• Destination if no answer: Core – Hangup

Every time the Manager’s extension is called, Asterisk will try to connect to extension
2001 and if no answer, it will call Ext. 2005 followed by the Reception. If still no answer, it
will simply hang up. During business hours, the reception will take down messages for
the manager or the Doctors.

Click “submit” followed by clicking the red bar on top of the screen to finalise this
selection.

5.4 Ring Groups

A ring group is a group of extensions that will ring when there is an external incoming call.
You can even put your Mobile Phone number in the ring group if you want to. The
0400123456# is the Medical Centre’s Manager phone (see illustration below). For mobile
phone to work, you must have the appropriate route and trunk set up.

You may not want a ring group – it’s entirely up to you. If you don’t require a ring group, you
may ignore this section.

When there is an incoming call to the ring group, the phones nominated in the selected
group will ring. You may select different ring group for each of the incoming trunk or you
may nominate the same group for all the trunks, in which case you will only need to define
only one ring group.

For simplicity, we will only defined 1 ring group for all incoming calls from all trunks – at
this stage, let’s not get too fancy.

We will create a ring group 600 for this purpose. Let’s call it AdminGroup as it rings all the
phones related to the Administration of the Medical Centre. A single digit ring group is not
recommended.

We have included the Manager’s Mobile Phone number in as the last one in the group. If
noone answer the call, Asterisk will simply hang up. Since the last number in the group is
the Manager’s mobile phone, generally, the Mobile phone voicemail will take the message
if the phon is not answered.

The ring group screen is illustrated below:

 5.4.1 Now it’s a good time to set up your softphones.

To do this, go to the chapter – Setting up Soft Phone and come back to the next
chapter after that is done.

If everything has been done as explained above, we should be able to make and
receive calls between our internal extensions. If not, it is time to re-inspect what we
have done above and make the necessary correction before attempting to go any
further.

Let’s take a break and test the soft phone extensions by making calls to each
extension that we have created.

TRIXBOX-2 Without Tears Page 40 of 224

6 TRUNKS TO THE OUTSIDE WORLD
Making and receiving calls between internal extensions is one thing, but a telephony
installation isn’t really an installation if you can’t receive and make calls to the outside
worlds.

To be able to do these, you will need at least one trunk to the outside world.

This is a simplified guide to give the budding Trixbox© users some understanding in
setting up Trunks.

Points to keep in mind.

Beware!!! If you are using an ATA, please allow for what the ATA will be sending
to asterisk when you are preparing you rules and patterns. If you want asterisk to
take care of all the rules, it is best to ensure that your ATA is sending exactly what
you dialled to Asterisk – just delete your dialling rule from your ATA and replace it
with (**|*x.|xx.)

6.1 What is a Dial Pattern?

Dial patterns are part of Outbound Routing. They act like a filter for matching numbers
dialled with trunks.

The various patterns you can enter are similar to Asterisk's definition of them:

• X — Refers to any digit between 0 and 9

• N — Refers to any digit between 2 and 9
• Z — Any digit that is not zero. (E.g. 1 to 9)
• [Various] — Match only one character that matches any of the one in the square
brackets. (E.g. [02-68*#] would match 0, any number between 2 and 6 inclusive,
8, * and #. Or, another way of saying this would be 'Match * or #, or a number that
isn't 1,7 or 9') –Avoid using this notation in your Trunk Dial Rule as it does not seem
to work. Use this only in your Outgoing Route Dial Pattern.
• . — Wildcard. Match any number of anything. Must match *something*.
• | — This lets you use a '0 to dial out' (or '9' in the US) by matching anything
before the line, but not sending it to the trunk.

6.2 What is a Trunk?

A trunk is the telephony service line that you will be using to make an external call on, e.g.
the Telstra telephone line that you have at home is a trunk (or it can be used as a trunk if
you wish but not necessarily so). A VOIP service provider (VSP) that you have signed up
with is also a trunk.

If you have paid for VOIP service to enabled you to make calls out through PSTN, you
can use this as a trunk for that purpose otherwise, you can only use it for making calls
using VOIP between subscribers of the VSP only (unless there are peering arrangements
with other VSPs).

You can have several trunks if you want to. You can have Telstra and/or Optus
telephone lines and use them as trunks, and you can also have a few VSPs that you
subscribed to as additional trunks.

To make external, PSTN or VOIP calls; you must have at least one trunk.

TRIXBOX-2 Without Tears Page 41 of 224

 The reason why asterisk users have several trunks can be explained as follows:

• Trunk (a) charges the best rate for Local calls but is expensive for Mobile calls and not so
great for international calls.
• Trunk (b) has great rate for international call.
• Trunk (c) has good mobile rate and will allow 1300 numbers while the other 2 do not.

A properly planned route will direct the phone calls you make to the appropriate trunk that
will provide you with maximum effectiveness and savings.

E.g. When you make a call to a Mobile phone, asterisk will route your call via trunk (c)
while it will route your call to trunk (a) if you make a local call. Similarly, when you make
an international call, asterisk will route your outbound call via trunk (b).

6.3 Trunks and Outbound Routes – a circus of confusion

To the uninitiated, Outbound Route Dial Patterns and Trunk Outgoing Dial Rules are
2 areas of confusion. I will try to explain this in the simplest possible term.

Each of these two works in conjunction with each other – they compliment each other
when an outgoing call is being made.

6.3.1 Outgoing Route Dial Pattern

This is the pattern you normally will dial when you want to make a phone call.
As an example, if you are living in Brisbane, and you are calling a friend who lives in
Sydney, you will normally dial a number such as 02 91234567, however if that friend
is in Victoria, you will need to dial 03 91234567.

Since your VOIP provider does not discriminate where you are calling from or where
you are calling to, it requires a universal type number to call so your call can be
directed to the correct recipient.

In most cases, the VOIP provider will need to dial the universal e164 format e.g.
61291234567 for Sydney or 61391234567 for Melbourne. (61 being the code for
Australia, 2 or 3 being the code for Sydney or Melbourne respectively, followed by
the telephone number of your friend which is 91234567).

Since you are dialling 03 91234567, asterisk only need to send 391234567 (without
the 0 prefix). Therefore in your Outbound Route Dial Pattern (lets call this Outgoing
Route Domestic) you will need the following pattern:

0|NXXXXXXXX

That pattern tells Asterisk to send only 9 digits out of 10 dialled by not sending the
first digit 0. Thus, if you dialled 0291234567, the number that will be sent to the
Trunk will be 291234567.

How will this then be translated to 61291234567? This is where the Trunk Outgoing
Dial Rule comes in.

6.3.2 Trunk Outgoing Dial Rules

This is what the trunk is required to send to the VSP to make a successful call to the
number you dialled.

Using the above example, assuming that the VOIP service provider requires the full
e164 format, Asterisk will need to add the missing Australian code 61.

TRIXBOX-2 Without Tears Page 42 of 224

 In your Trunk Outgoing Dial Rule, you will need the following pattern.

61+NXXXXXXXX

That pattern tells Asterisk to add 61 in front of the 291234567 before dialling the
number via the trunk. For variations of patterns, see What is a Dial Pattern in the
previous chapter earlier on in this document.

6.4 Let’s Create The VoIP Trunks

To create a new trunk using freePBX, select Setup tab and then select the Trunks option
from the vertical menu on the left.

For this example, let’s create 2 SIP trunks; Pennytel and Oztell.

Pennytel will be used for all International and mobile calls

Oztell will be used for all local and mobile calls.

To create a new Trunk, click on the Add Trunk option (first option on the right of the
screen).

General Setting (This applies to all the trunks):

Outbound Caller ID: “Insert Your Name” <Your Number> (Must include the “ “ and <>)

Maximum channels: Leave blank for maximum.

In this example we will create a Pennytel and Oztell SIP Trunks, which we will call
pennytel and oztell respectively. We will also define their dialling patterns.

6.4.1 Pennytel
In this example, we will use Pennytel for all international and mobile calls only.

Pennytel requires numbers dialled to follow the international format Country code +
area code + phone number. To call an overseas destination you would normally dial
0011+country code + phone number. E.g. to call New Zealand is 0011 64 <phone
number>, and to dial France is 0011 33 <phone number>. Since Pennytel only requires
the country code and the phone number but does not require the 0011, the route (that
we will create later) will not pass the 0011 to the trunk.

We will require the following Outgoing Dialling Rules for this trunk, which instruct the
trunk to dial whatever is sent by the appropriate route. This example is for dialling
Malaysia with a country code of 60, and Australian Mobile phones.

Pattern Explanation
This pattern tells Pennytel to dial all Malaysian Mobile numbers
601XXXXXXXX
starts with 601 followed by 8 more digits.
This pattern dials numbers start with 60 followed by a one-digit
60NXXXXXXX
number in the range of 2-9 followed by 7 more digits.
For dialling Australian Mobile phone. The 61 is the Australian
61+4XXXXXXXX
Country code that will be added to the mobile phone number.

601XXXXXXXX
In your Outgoing Dial Rules box, we will enter the
60NXXXXXXX
following; 61+4XXXXXXXX

Next we need to create the Outgoing Setting, Incoming Settings and Registration for
Pennytel.

TRIXBOX-2 Without Tears Page 43 of 224

 Outgoing Settings
In the Trunk Name field we will enter the name of this trunk: pennytel

allow=alaw&ulaw&gsm
canredirect=no
In the Peer Details enter the following; canreinvite=no
Pennytel preferred codecs are: g729, gsm disallow=all

username=888XXXXX

Registration
In the registration field, enter the following:

888XXXXX:Password@sip.pennytel.com/888XXXXX

After all these have been done, click on the Submit Changes button and click on the
red bar across the top of the screen.

It seems that Pennytel is rejecting Asterisk. To overcome this problem, it is

necessary to add the following in the general section of your sip.conf.

useragent = Trixbox

The useragent can be any name, as long as it is NOT Asterisk.

My sip.conf looks like this;

; Note: If your SIP devices are behind a NAT and your Asterisk
; server isn't, try adding "nat=1" to each peer definition to
; solve translation problems.

[general]

port = 5060 ; Port to bind to (SIP is 5060)

; you call in you get a message saying "The number you have dialled is not in service.
; Please check the number and try again."

tos=0x68
useragent = Trixbox

; #, in this configuration file, is NOT A COMMENT. This is exactly how it should be.
#include sip_nat.conf
#include sip_custom.conf
#include sip_additional.conf

6.4.2 Oztell (SIP)

Oztell requires the numbers dialled to follow international format Country code + area
code + phone number. To call Sydney 67541234, Oztell requires it in the following
format 61 267541234. To use Oztell family cheap rate you can also prefix it with 09.
Therefore the dialling rule will be in this form:

We need various patterns here:

Pattern Explanation
899060X. This pattern tells Oztell to dial the inter Oztell’s numbers
This pattern dials numbers start with 60 followed by a one
digit number 1-9 followed by other numbers minimum of 2
60ZXX. digits from 0 -9. This can be an international number with a
Country code of 60 followed by a number between 1 and 9
inclusive.
06612+NXXXXXXX Using the Oztell 06 rate to dial any NSW number.
0661+NXXXXXXXX Using Oztell 06 rate to dial any Australian number.
61+1300XXXXXX Dials 1300 numbers
61+13ZXXX Dials 13 numbers
61+1800XXXXXX Dials 1800 numbers

899060X.
In your Outgoing Dial Rules box, it will look like this: 60ZXX.
– this is simply an example based on my setting; 06612+NXXXXXXX
yours will no doubt be different. 0661+NXXXXXXXX
61+1300XXXXXX
61+13ZXXX
61+1800XXXXXX

Next we need to create the Outgoing Setting, Incoming Settings and Registration for
Oztell.

 The SIP Trunks screen in freePBX will look like the following illustration below:

* For more trunk settings, please refer to APPENDIX B

Now that you know what the trunk will do, you may proceed to the next chapters to
create the Inbound and outbound routes.

TRIXBOX-2 Without Tears Page 47 of 224

7 CALLS HANDLING
7.1 Inbound Routes (Incoming Calls)
This is where the behaviour of incoming calls from all trunks is being handled.

When an incoming call from PSTN or VoIP trunk is received, asterisk needs to know
where to direct it. It can be directed to a ring group, an extension, Digital Receptionist
(IVR) or Queue. For this purpose, Inbound Route needs to be set up.

Select the Inbound Routes selection in the left bar of the screen.

Initially, (since we have not created an IVR yet) we will set all incoming calls to be
directed to Ring Group 600 as illustrated below (later on in this guide we will create a
digital receptionist for this purpose and we will redirect all the incoming calls to the IVR).

As a matter of fact, this can be the only Inbound Route that you will need if
you deploy IVR (to be discussed later on). Besides, without this inbound
route created, your 7777 simulated calls will not work.

For our purpose, only put in the following data. The rest are optional.

• DID Number: Leave blank

• CID Number: Leave blank

TRIXBOX-2 Without Tears Page 48 of 224

 • Fax Extension: Disabled (I do not require fax facility here)
• Privacy Manager: No
• In the radio button, enable Ring Group 600 (AdminGroup). We want all
incoming calls to ring the phones in the Admin group (see illustration below).

For each extra trunk, a corresponding inbound route may be created (you don’t have to).
All incoming calls from all the different trunks that you may have can have their own
individual characteristic by judicious deployment of the time condition facility available in
FreePBX (to be discussed later on).

However, at least one Inbound Route must be created for Trixbox© to answer incoming
calls. This includes calls from PSTN trunk as well. The route that we have created above
is precicely for this purpose.

This route will handle the calls that come in without Trunk ID and calls from trunks that do
not have an Inbound Route created (which includes all calls from PSTN and incorrectly
created incoming route). We call this a “Catch-All” route, an Inbound Route with the DID
Number and Calling ID Number fields left blank.

As usual, you will need to click on the red bar on top of the screen after each time you
submit a new Inbound Route.

TRIXBOX-2 Without Tears Page 49 of 224

 7.2 Time Conditionds
You can create various time conditions and use these time conditions in conjunction with
your Inbound Route to individualise each of the incoming trunk’s behaviour.

TRIXBOX-2 Without Tears Page 50 of 224

 You may create several time conditions and give each of the time condition a Short Name
to identify it. These time conditions can then be assigned to each individual Inbound
Route if you choose to do so or they can be nested.

7.2.1 Simple Time Condition

Unlike businesses, most private householders, ignore the time condition, instead
would prefer to direct all calls to an extension or selected extensions regardless
whether it is day or night. If this is the case, you may ignore time condition
altogether, instead, use the inbound route to direct your incoming calls to individual
extensions or to the digital receptionist. However, if you want to accept calls during
the day but prefer callers to simply leave voice messages during the night, below is
an example of a simple time condition that you can adopt where the time condition
will send the calls to IVR during the hour of 8:00am and 8:00pm and anything outside
the stipulated hours, the calls will be directed to your voicemail.

• Add a new time condition by selecting Setup - > Time Condition - > Add
time condition.
• In the Time condition name field, give it a name eg: DayNight
• Under Time to match, do the following:
o Time to start: 08:00
o Time to finish: 20:00
o Week Day start: Monday
o Week Day finish: Sunday
• Under Destination if time matches, select IVR (or Core extension or ring
group)
• Under Destination if time does not match, select Core mailbox: eg
voicemail box 2001 (if you have voicemail enabled for ext. 2001).
• Submit and click on the red bar on top of the page.

Once the above is done, go to Inbound Route, select the appropriate inbound route
and under Set Destination, select Time Condition DayNight, submit and click the red
bar on top of the screen.

7.2.2 Complex Time Condition

A slightly more complex one can also be crafted e.g: You want o accept calls only
between 8:00am till 1:00pm and between 2:00pm and 5:30pm Monday to Friday and
any other time you want to direct all the calls to voicemail.

1. Add a morning time condition.

• Add a new time condition by selecting Setup - > Time Condition - > Add
time condition.
• In the Time condition name field, give it a name eg: OfficeMorning
• Under Time to match, do the following:
o Time to start: 08:00
o Time to finish: 13:00
o Week Day start: Monday
o Week Day finish: Friday
• Under Destination if time matches, select IVR (or Core extension or ring
group)
• Under Destination if time does not match, select a core extension for the
moment. We will need to change this later.
• Submit and click on the red bar on top of the page.

2. Add an afternoon time condition

• Add a new time condition by selecting Setup - > Time Condition - > Add
time condition.
• In the Time condition name field, give it a name eg: OfficeAfternoon
• Under Time to match, do the following:
o Time to start: 14:00

TRIXBOX-2 Without Tears Page 51 of 224

 o Time to finish: 17:30
o Week Day start: Monday
o Week Day finish: Friday
• Under Destination if time matches, select IVR (or Core extension or ring
group)
• Under Destination if time does not match, select Core mailbox: eg
voicemail box 2001 (if you have voicemail enabled for ext. 2001).
• Submit and click on the red bar on top of the page.

3. Go back to time condition OfficeMorning and change the Destination if time

does not match to: Time Condition OfficeAfternoon. Submit and click on the
red bar on top of the screen.

4. Once the above is done, go to Inbound Route, select the appropriate inbound
route and under Set Destination, select Time Condition OfficeMorning, submit
and click the red bar on top of the screen.

What the inbound route will do is, as soon as an incoming call is accepted, it will be
forwarded to the OfficeMorning time condition.

If the time condition is met, it will then be forwarded to the IVR. On the other hand, if
it does not match, it will be forwarded to time condition OfficeAfternoon.

If it matches the OfficeAfternoon time condition, the call will be forwarded to IVR, if
not, it will be forwarded to the voicemail box that you have determined.

Following the above example, time conditions can be nested to multiple levels deep
allowing you to manage your time condition and make them as complex or as simple as
the situation demands – imagination is the only restricting factor.

7.3 Outbound Routes

7.3.1 What is an Outbound Route?
An outbound route works like a traffic cop giving directions to road users to use a
predefined route to reach a predefined destination.

7.3.2 How does it work?

Every time you dial a number, asterisk will do the following in strict order:

• Examine the number you dialled.

• Compare the number with the pattern that you have defined in your route 1
and if matches, it will initiate the call using that trunk. If it does not match, if
will compare the number with the pattern you have defined with route 2 and
so on.
• Pass the number to the appropriate trunk to make the call.

To make an external call (except inter extension calls), you will need at least
one trunk and one route.

In this case we will create 5 routes:

• International
• Domestic
• MobileAust

TRIXBOX-2 Without Tears Page 52 of 224

 • OztellOnly

The International Route will be used for all international phone calls.
The Domestic Route will take care of the Australian phone and mobile.
The other two will do as the names suggest.

To create a new route using freePBX, select Setup tab and then select the
Outbound Route option from the vertical menu on the left.

Click on the Add Route in the menu on the right of the screen.

7.3.3 International
You will need the following pattern to match international dialing.

Pattern Explanation
Most of my International calls are to Malaysia, I have defined
0011|60NXX.
the Malaysian PSTN pattern here.
This pattern dials all international numbers by prefixing it with
0011 and any digit between 7 and nine inclusive. Before the
0011|[7-9]XX.
number is sent to the trunk the 0011 will be stripped. If
required by the trunk, the trunk will insert the 0011.
This is the catchall international dialling including International
0011|NXX.
Mobile (excluding USA which is a 1).

TRIXBOX-2 Without Tears Page 53 of 224

 In your Dial Patterns box, you will see something like this.

Dial Patterns

0011|60NXX.
0011|[7-9]XX.
0011|NXX.

You will then need to pick the Trunk Sequent. In this case we will use Pennytel as
the trunk for this route and if it fails, we will use Oztell as a second choice/backup.

Trunk Sequence

0 Pennytel
1 Oztell

Any number dialled with the 0011 prefix will be routed through the Astratel trunk and
should it fail, it will be routed to Pennytel.

7.3.4 Domestic
You need the following pattern to match the Australian Telephone numbers and the
Australian Mobile numbers.

Pattern Explanation
You will dial Australian telephone number as normal
using 03, 02 prefix but the route will strip the leading
0|[23478]XXXXXXXX
0 before it is sent to the trunk.
If the trunk requires the 0, the trunk will insert it.
If you dial local number and not use the STD prefix, it
will send to the trunk as is and the trunk will insert the
[2-9]XXXXXXX
02 if required (this is a NSW pattern. If you are in
Victoria you will need to modify the trunk).
This is the catchall dialling for numbers that does not
ZXX.
start with a 0 such as 1300, 1800, 13 etc.

In your Dial Patterns box, you will see something like this.

Dial Patterns

0|[2378]XXXXXXXX
[4689]XXXXXXX
ZXX.

You will then need to pick the Trunk Sequent. In this case we need Oztell as the
trunk for this route and if it fails, we want Pennytel to take over as a second
choice/backup.

Trunk Sequence

0 Oztell
1 Pennytel

All numbers dialled matching the above pattern will be routed through Oztell and if it
failed, it will be routed via Pennytel.

TRIXBOX-2 Without Tears Page 54 of 224

 7.3.5 MobileAust
There is only a single pattern for calling Australian mobile – illustrated below.

Dial Patterns

0|4XXXXXXXX

We want all my domestic mobile calls to be routed via Pennytel and we have not
nominated a second trunk. If it fails then we will not be able to make a Mobile call, as
we don’t have a second trunk nominated.

Trunk Sequence

0 Pennytel

7.3.6 Oztellonly
The following pattern is in the Oztellonly route. We will use Oztell for a number of call
types therefore some explanation may be in order.

Pattern Explanation
This pattern will allow me to dial a Malaysian Mobile number.
The 0011 will be stripped before the number is sent to Oztell.
0011|601XX.
Oztell does not require the 0011. It only requires the Country
code.
You will dial Australian telephone number as normal using
03, 02 prefix but the route will strip the leading 0 before it is
0|[378]NXXXXXXX
sent to the trunk.
If the trunk requires the 0, the trunk will insert it.
1[38]XX. This is for dialling 1300, 1800 and 13 numbers.
899060XX. For dialling Oztell inter Oztell users
NXXXXXXX Catchall for dialling a local number that doesn’t start with 1

In the dial pattern box you will see something like the illustration below.

Since the above pattern is for Oztell only, in my trunk sequence, Oztell was chosen to
be the only trunk for any of these calls.

 7.4 ENUM
ENUM is a way for us to use VOIP to establish calls between VOIP systems without using
PSTN even though the numbers called are PSTN numbers provided that the numbers
called are registered with ENUM. In short, ENUM offers you the ability to call other
telephones directly over the Internet without involving a third party.

I will not enter into any elaborate explanation how enum works, as there are already a
number of articles describing this. In essence, your phone number and server information
are stored in a special DNS zone (very similar to a reverse lookup zone). When an
ENUM enabled Asterisk user calls your phone number, it will first attempt to find your
phone number in the ENUM DNS zone. If it finds your phone number it will use the
information to setup a call directly between his Asterisk server and yours, resorting to
PSTN only if your number is not found.

Note: ENUM only works between ENUM enabled Asterisk (or other ENUM enabled VOIP)
users.

7.4.1 Setting up ENUM Trunk

1. Click the Add Enum Trunk link.

2. In the Outbound Caller ID field enter your callerid information in the format of
"Your Name" <61246123456> (Including the quotes), assuming your telephone
number in Sydney is 0246123456.
3. On the outgoing Dial Rule enter 612+NXXXXXXX (for local calls without having to
dial the 02)
4. On the second line enter 61+NXXXXXXXX (for dialling Australian numbers where
you need to dial the prefix (eg. 03)
5. On the next line enter ZXXXXXXXX. (including the dot) for dialling International
numbers – see example below:

6. Click the Submit Changes button at the bottom of the page

TRIXBOX-2 Without Tears Page 56 of 224

 7. Click the Apply Configuration Change at the top of the page.

7.4.2 Setting up ENUM Outbound Route

1. Click the Outbound Routing link on the left hand side.

2. In the routes window on the right-hand side, click the route you would like to
enable with ENUM. I call my route e164.
3. We will to use the prefix 164 to force dial through ENUM
4. In the Dial Pattern, on the first line, we insert 1640|[378]NXX. This will allow us to
dial an STD number such as 0732123456 by dialing 1640732123456 where only
the 732123456 will be sent to the ENUM trunk.
5. On the second line we insert 1640011|NXX. This will allow us to call an
International number eg. To call Malaysia we will dial 16400116062861234 and
only the 6062861234 will be sent to the ENUM trunk.
6. On the third line I have 164|NXX. This enamels me to dial NSW local number
without having to dial 02.
7. Make the ENUM trunk the first route in your Trunk Sequence. You may also
add other trunks in the sequence in case ENUM failed.
8. Click the Submit Changes button at the bottom of the page.
9. Click the Apply Configuration Change at the top of the page.
10. You may try calling someone while monitoring Asterisk CLI and you should see
the Enumlookup scroll by.

8 HOW TO RESTRICT OUTGOING CALLS
This requirement often manifests itself in an office environment where management
restricts staff from making International, long distance, or even local calls. In many
organizations, staffs are confined to making internal calls only.

There is no easy way of imposing this restriction through the freePBX GUI. The only way
that can be done currently is to introduce special scripts in the extensions_custom.conf
file or create a special .conf file. For now, we will stick with the simplest method.

It is somewhat complicated, but I will try to explain it here and provide an example.

1. Set up all your trunks and outbound routes as normal. At this stage, users can make
unrestricted calls. This is the normal way of doing it with freePBX. You probably
would have already done this.

2. Through Config Edit of Trixbox©, open extensions_additional.conf and locate the

[outbound-allroutes] section of the file. You will notice something like my example
below.

[outbound-allroutes]
include => outbound-allroutes-custom
include => outrt-001-PSTN
include => outrt-002-SPA3K
include => outrt-003-Oztell
include => outrt-004-Pennytel
include => outrt-005-Domestic
include => outrt-006-MobileAust
include => outrt-007-International
include => outrt-008-12Number
include => outrt-009-13N1800Numbers
include => outrt-010-e164
include => outrt-011-SingaporeLink
include => outrt-012-KualaLumpurLink
include => outrt-013-MalaccaLink
exten => foo,1,Noop(bar)

; end of [outbound-allroutes]

Highlight them, copy and paste in a notepad text file somewhere and will get back to
this a little later.

Alternatively you can paste it directly to extensions_custom.conf. Do not do this if

Trixbox© is active as it may cause some problem while people using it.

3. Through Config Edit of Trixbox©, open extensions_custom.conf and create a

section like my example below. You can get the codes from [from-internal-
additional] of extensions_additional.conf. So will have to do some juggling
because you can’t cut and paste this from another .conf file without having to close
one (you can cut and paste from here if you like).

;

Now copy your [outbound-allroutes] that was saved to the text file directly underneath
the last line of the above context. Remember to delete the [outbound-allroutes] label.
Unfortunately you can’t cut and paste my example because they are my routes NOT
yours.

Your final handiwork will look something like the example below:

include => outrt-013-MalaccaLink
exten => foo,1,Noop(bar)
;
; end of outbound-restricted-routes

Now add the following codes underneath that to finish it off.

;
exten => h,1,Hangup
exten => s,1,Macro(hangupcall)
exten => h,1,Macro(hangupcall)

4. You may now comment out the outbound routes you do not want the restricted
extensions to use.

E.g. If you comment out include => outrt-001-PSTN, the restricted extension
cannot use PSTN.

5. After you have done that, you need to go back to FreePBX and edit the extension that
you want to restrict by change the context to from-restricted instead of from-internal.

Now go enjoy yourself with it.

9 SYSTEM RECORDINGS
System recording is a facility available under freePBX to enable the recording of
customised voice prompts etc.

By now we should be able to navigate ourselves through the freePBX menu. To get to
the system recordings, select the Setup tab and pick System Recordings as per the
illustration below.

Clicking on the System recording label as highlighted by the red arrow will open the
following “System Recordings” screen.

TRIXBOX-2 Without Tears Page 61 of 224

 There are two methods that you can capture your recording:

• By recording directly using your telephone

• Uploading pre-recorded materials

9.1 Direct recording

Enter the extension number of the mouthpiece that you will be using to record your
message in the appropriate field.

You will be making your recording using the telephone on this extension (or the
microphone of the softphone).

Click Go.

Follow the prompt on the screen and dial *77 on your phone to do your recording now.

In my message, I have asked one of the receptionists to record the following:

“Hi, you have reached the Family Health Centre. Press 1 for Reception, 2 for the
Centre’s Manager, 3 for Dr. Roberts, 4 for Dr. Forbes, 5 for Dr. Wong, 6 for the Admin
Office, 7 for Lab and X-Ray or you may simply hold and your call will be answered by one
of our available receptionists. If no one answers your call, please leave a message”. -
Then hang up.

TRIXBOX-2 Without Tears Page 62 of 224

 Verify the recording by dialling *99. Go to step 1 again if you are not happy with the
recording. Keep doing this till you are satisfied.

Once you are happy with the recording, give the recording a descriptive name e.g.
“MainMenu” so you will know what the recording is for.

Click Save.

9.2 Upload Pre-recorded Material

If you have a recording that you have prepared in a .wav format you can simply upload
that recording by browsing you local hard drive, locating the file that you want to upload
and upload it to Trixbox.

Follow the prompt for the upload and once again when the upload is completed, give the
file a descriptive name for you to know what that recording is for.

The above recorded files either recorded manually or uploaded using the system
recording facility will be stored in the /var/lib/asterisk/sounds/custom directory.

TRIXBOX-2 Without Tears Page 63 of 224

10 DIGITAL RECEPTIONIST
Like most organisation, where possible, we would like to automate the redirecting of all
incoming calls. The digital receptionist is very handy for these sorts of things. Unless the
calls are non-specific and will need the assistance of the receptionist (in our case also the
operator), the system should allow callers to make the selection.

10.1 Setting Up Digital Receptionist

In the Setup tab, click on the IVR option and get the following screen.

Click on the Add IVR option on the top right on the screen (see arrow) and the new
Unnamed IVR configuration screen will be presented to you.

We will then fill in the following fields:

TRIXBOX-2 Without Tears Page 64 of 224

 Name (Change Name): MainMenu (that’s what we shall called the main menu)
Timeout: 10 (leave it at default)
Enable Directory: Tick
Directory Context: Leave it at Default
Enable Direct Dial: Tick
Announcement: MainMenu (That’s what we called the IVR recording that was made for this
purpose)

(see illustration below)

Then proceed to enter the selection options that you require for this IVR when the caller
presses the appropriate option.

If you need more choice options in the IVR, click on the Increase Options button at the
bottom of the screen.

In this IVR, we have defined our requirement as outlined below:

For number 1 - 7, we select Extension, and for 8, which we have changed to the letter “t”,
we also selected Extension.

For 1, we will select the Reception (Extension 2000).

For 2, select 2001, which is the Manager’s extension.
For 3, select Dr. Roberts (Extension 2002)
For 4, select Dr. Forbes
For 5, select Dr. Wong
For 6, select Admin Office
For 7, select Lab and X-Ray
For 8, (which we shall change to “t”) select extension 2000, which is the reception.

TRIXBOX-2 Without Tears Page 65 of 224

 The last extension (which we have changed to the letter “t”) is to capture timeout, if the
caller does not press any option or, in case the DTMF tone does not register, the call will
be sent to the receptionist.

Once finished, click Save and also click on the Apply Configuration Changesed on the
top of the screen.

Test it by dialling 7777, (Asterisk will simulate an incoming call) and you will hear your
Digital receptionist in action.

 10.2 Multi-Language IVR
(This is included in this section as an example only and is not part of this tutorial. However you
can use this if you want to).

Trixbox© allows multi languages IVR handling by simply telling Trixbox© what language
to use. Naturally you will need to install all the language sets that you wish to use.

See Installing Other Languages in the chapter referring to Customised Voice in later part
of this document.

I am assuming that you already have your MainMenu IVR in English set up for selecting
various options. This IVR is known as IVR-2 in your extension_additional.conf file. Any
subsequent IVR created will be IVR-3, IVR-4 and so on.

You will need to create another IVR for selecting the language options that you want to
present to the callers. This will be the IVR that will greet all callers with Select 1 for
English, 2 for Italian etc. In this example, we will have 2 language sets, Australian and
Italian. Let us name this second IVR LanguageChoice.

Being the second IVR you have created, this IVR will be known as IVR-3 in your
extension_additional.conf file. Any subsequent IVR created will be IVR-4 and so on.

In LanguageChoice, we will have 3 options.

• Select 1 for Australian English

• Select 2 for Italian
• The third option is unannounced as it will be the time out option represented by
the letter “t”. This option is the option the IVR will defaulted to if no choice is
made or if the caller’s DTMF tone is not recognised by Trixbox©.

In choice 1, select the Custom App: radio button and enter the following in the box:

Custom App custom-language_au,s,1

In choice 2, select the Custom App: radio button and enter the following in the box:

Custom App custom-language_it,s,1

The third choice, instead of a number, you will enter the letter “t” in the option box, select
Custom App: radio button and enter the following:

Custom App custom-language_au,s,1

Next, you will need to do a little editing of the extensions_custom.conf file. You need to
add the following towards the end of your extensions_custom.conf.

You will also need to create another IVR called MainMenu_IT with options to be
presented in Italian. This is similar to your main IVR except that it is presented to the
caller in Italian. This IVR being the third that you have created will be referred to as IVR-4
in the extensions_additional.conf file.

[custom-language_au]
exten => s,1,Set(LANGUAGE()=au)
exten => s,n,Playback(vm-dialout)
exten => s,n,Goto(ivr-2,s,begin)

[custom-language_it]
exten => s,1,Set(LANGUAGE()=it)

TRIXBOX-2 Without Tears Page 67 of 224

 exten => s,n,Playback(vm-dialout)
exten => s,n,Goto(ivr-4,s,begin)

Save it and re-read the configuration change and you are done.

Now you will need to change your inbound route to point to the LanguageChoice IVR.
All calls will then be greeted by the LanguageChoice IVR and when the caller select 1 (or
2), the IVR will call the appropriate exten. If the caller selected 1, the [custom-
language_au] will be selected and the language will be set to Australian English, an
announcement in the appropriate language will be made and the caller will be sent to the
MainMenu (or MainMenu_IT) for call options (you must also have recorded the call
options announcement in the various languages).

10.2.1 Complimentary multi-language MOH

To take the multi-language IVR one step further, we can also have multi-language (or
multi category) MOH to compliment the language.

If the language used is Italian, it is safe to assume that the caller is Italian and would
much prefer to listen to Italian music instead of Chinese or Arabic music.

To do this you will need to have the appropriate MOH music in Trixbox©.

Assuming that you already have the default music category that comes with Asterisk,
you will need to create a new music category using freePBX On Hold Music option.
Let us call this new category ItalianTune.

See the chapter relating to MOH in the later chapter of this document.

Once you have created this category, upload a few MP3 Italian music/Tunes to it. If
you want the tune to be randomised, click the Enable Random button and you are set
to go.

You will need to modify the 2 scripts above to the following:

[custom-language_au]
exten => s,1,Set(LANGUAGE()=au)
exten => s,n, SetMusicOnHold(default)
exten => s,n,Playback(vm-dialout)
exten => s,n,Goto(ivr-2,s,begin)

[custom-language_it]
exten => s,1,Set(LANGUAGE()=it)
exten => s,n, SetMusicOnHold(ItalianTune)
exten => s,n,Playback(vm-dialout)
exten => s,n,Goto(ivr-4,s,begin)

You may have to restart asterisk after this (although it may not be necessary).

Now you will have multi language IVR as well as the complimentary MOH.

TRIXBOX-2 Without Tears Page 68 of 224

 10.3 Multi-Tenants IVR
(This is included in this section as an example only and is not part of this tutorial. However you
can use this if you want to).

While freePBX is a very versatile GUI front-end for Trixbox© it does not have the facility to
configure a PBX for multi-Tenants application. However, Trixbox© (Asterisk) has the
ability to do it with a little creative manipulation.

In the chapter above we covered multi languages IVR handling by simply telling Trixbox©
what language to use. We are going to use the same principal to handle the Multi-
Tenants requirement.

In this example, I will use a Medical Centre in Malaysia, that I have the privilege of
installing the Asterisk PABX for. There are 3 tenants involved – a General Practitioner, a
Dental Practitioner and a Pathology representative. Each has separate incoming
telephone numbers with their own receptionist but using a common PABX.

I have picked this organisation as an example because it is small enough to write about.
If I choose one of my bigger installations, this book will never see the light of day ☺

The main requirements are pretty straightforward:

• Calls that come in through the different tenants should be directed to the
appropriate IVR. One IVR for each tenant.
• 12 extensions - 4 for Dental Practitioner, 3 for Radiologist and 5 for General
Practitioners.
• Voicemail for each receptionist.

There are other requirements such as multi language prompts, after-hours ring groups,
time conditions, Interlinking 2 Trixbox© boxes between the Medical Centre and the
Pathology Main Office in Kuala Lumpur etc., but I have only listed the major requirements.

In this example I will only highlight the Multi-Tenants incoming route handling and
restricting outgoing calls to the appropriate telephone lines only.

The full case study can be found in the Appendix titled, Live Case Study at the end of
this document.

My first task was to install the base Trixbox© as per the chapter on Installation. In this
installation, there is no VOIP trunk involved. All telephone communications are through
PSTN lines apart from the Trixbox© inter-connect between the Medical Centre and the
Pathology Main Office in Kuala Lumpur, which will be done via a DSL connection.

PSTN Interface
2 x TDM400 were installed in the PC designated for the PBX

• 3 ports allocated to the General Practitioners (ports 1-3)

• 3 ports allocated to Dental (ports 4-6) and
• 2 ports allocated for Pathology (ports 7-8).

IVR Prompts
3 x IVR were created, one for each of the different tenant.

• MedicalIVR (represented by ivr-3 in extensions_additional.conf)

• DentalIVR (represented by ivr-4 in extensions_additional.conf)
• PathoIVR (represented by ivr-5 in extensions_additional.conf)

TRIXBOX-2 Without Tears Page 69 of 224

 Each IVR will act as a traffic cop to direct calls to the appropriate extensions belonging to
each tenant.

Inbound Routings
• ZAP channels 1,2 and 3 (3 PSTN numbers for GP) routed to MedicalIVR
• ZAP channels 4,5 and 6 (3 PSTN numbers for Dentist) routed to DentalIVR
• ZAP channel 7 and 8 (2 PSTN numbers for the Pathology representative) routed
to PathoIVR

Extensions

1. Extensions 2000 to 2004 allocated to GP

• 2000 for Receptionist/Clerk with voicemail

• 2001 for Doctor A
• 2002 for Doctor B
• 2003 for Surgery Room
• 2004 for Dispensary

Change the context of these extensions, from [from-internal] to [from-internal-medical]

2. Extensions 3000 to 3003 allocated to Dental

• 3000 for receptionist/clerk with voicemail

• 3001 for Dentist A
• 3002 for Dentist B
• 3003 Spare extension

Change the context of these extensions, from [from-internal] to [from-internal-dental]

3. Extensions 4000 to 4002 allocated to Pathology

• 4000 for receptionist/clerk with voicemail

• 4001 for Radiographer
• 4002 for Assistant

Change the context of these extensions, from [from-internal] to [from-internal-pathology]

Outbound Calls Handling context

Create 3 different call handling contexts in the extensions_custom.conf configuration
file.

• [from-Internal-medical]
• [from-internal-dental]
• [from-internal-pathology]

The purpose of these contexts is to restrict extensions belonging to each tenant to be

confined to telephone lines belonging to that particular tenant when making external calls.
See How to restrict outgoing calls in the Calls Handling chapter earlier in this document.

All of the basic set up requirements above are explained in the various chapters of this
book and should not present any difficulty to complete.

Once the basic is completed, the rest of the variations and extras can be handled as per
the individual requirement.

11 GET UNDER THE BONNET

Config files manual tweaks in this guide are meant for advanced users.
Unless you have a compelling reason to do so, users are advised against
any manual config file tweaks.

Just as you think that all is OK, you realized something else requires attention. This is
true with Trixbox© as well.

To do this we may need to edit some configuration files (.conf) that reside both in the
/etc/asterisk directory and /etc directories. Configuration files in the /etc/asterisk are
generally editable through Config Edit.

To start editing the .conf files we need to hover on the Asterisk tab and select the Config
Edit selection from the dropdown menu as illustrated below.

Select Config Edit (marked with red arrow) and we will see a new screen with a list of all
the .conf files, which can be edited manually.

Scroll down the page to find the file that needs to be edited.

TRIXBOX-2 Without Tears Page 71 of 224

 11.1 Editing The .conf Files
A number of .conf files may require editing to get asterisk to work, depending on the
individual requirements. In this guide, as a base, we will be looking at sip.conf, iax.conf
(just in case you want IAX, but not really necessary if you are just running SIP),
indications.conf, enum.conf, extensions_custom.conf, features.conf, zaptel.conf
and modprobe.conf (the last 2 files live in the /etc directory and may need to be edited if
you have a FXO card e.g. X100P installed. We will look at them later on under
Interfacing Asterisk to PSTN).

11.1.1 sip.conf

[general]

port = 5060 ; Port to bind to (SIP is 5060)

bindaddr = 0.0.0.0 ; Address to bind to (all addresses on

Every time you update freePBX, there is a good chance that changes or
additions you have made in sip.conf will be overwritten. To avoid this,
all additions I wish to make in sip.conf are made in sip_custom.conf

11.1.5 extensions_custom.conf
If you have a ZAP trunk and you want to get an external line and be presented with a
dial tone first before you dial the external line, you may add the following codes in the
extensions_custom.conf file.

The example below assumes that your ZAP is on channel 1.

Immediately after the line following the include => from-internal-Trixbox context,
insert the following codes:

exten => 0,1,Dial(ZAP/1/{EXTEN})

exten => 0,2,Hangup

This will allow you to dial 0 and you will get a second dial tone from PSTN. Following
which you can dial a PSTN number that you wish to call.

If you're using a PRI line, you need to enable 'overlapdial' in

/etc/asterisk/zapata.conf for this to work.
.

11.1.6 features.conf
The default features.conf included with Trixbox© is fairly minimal. It is recommended
that you reflect the following in your features.conf file. The extra keywords will come
in handy later on.

12 CHECK YOUR SYSTEM
After doing all of the above, you will no doubt feel frustrated if your VOIP does not work.

The following are some basic steps for you to do – at least to ensure that your installation
is running correctly and is registered to the appropriate VSP before you start doing
anything more adventurous.

There are two places where you can obtain a quick health report of your system – the
System Process Status and the Asterisk Info screens.

If you don’t have the Asterisk Info option, refer to the NOTES section on how to
obtain this module.

12.1 System Process Status

First you must ensure that asterisk is well and running or you may not be able to make or
receive any call.

If all processes are running then your battle is half won.

To do the initial checking, let us start with the System Maint option of Trixbox© System
Menu.

Hover the mouse on the System tab and select the System Maint selection from the
dropdown menu as highlighted by the red arrow below.

Clicking on the System Maint selection will open the Process Status screen.

When your maintenance screen is presented to you, all the processes should be running
as illustrated in the Process Status screen below.

TRIXBOX-2 Without Tears Page 76 of 224

 If any of the four services aren’t running, chances are something is wrong and your
Asterisk will not be working correctly or not working at all. A probable cause can be
wrong configuration of your zaptel drivers. If you don’t have a zaptel devise, you should
try to disable the related .conf files.

Ensure that the minimum requirements have been met. If the minimum requirements and
the right type of hardware requirements have been met, and yet it is still not working, then
maybe its time to start the installation again.

Next, select and click Asterisk Info to verify your status.

12.2 Asterisk Info

From freePBX, select the Asterisk Tab and click on the Asterisk Information option as
shown by the red arrow.

When presented with the info page, scroll down to the SIP (or IAX if you are using IAX)
section and ensure that you are registered to your trunks. You will only be able to make
and receive external calls – hopefully - if you are registered.

See illustration below.

TRIXBOX-2 Without Tears Page 77 of 224

 If all trunks are registered, you can be almost certain that at the very least, your Trixbox©
installation is working (although not necessarily that you can make or receive calls).

In the majority of cases, if you have done everything as described in the preceding
chapters, the chances of your installation working are pretty good. However there are
always times when you think that the weather is going to be fine and yet you are pelted by
a thunderstorm.

If you are not able to make or receive calls, the most common causes are Trunk
Registrations, the choice of Codec, Routings, and Dialling rules errors.

Routings and Dialling rules are something that needs to be thought out logically with no
simple way of determining, as different people has different requirements and different
VSP have different dialling rules.

13 INTERFACING ASTERISK TO PSTN
If you are using TRIXBOX v1.0, please refer to section 10.3 before proceeding as there is
a little problem of TRIBIX not recognising ZAP device. This issue has been addressed in
later versions of TRIXBOX© .

13.1 X100P FXO PCI Card

Digium does not make the X100P card any longer, but there are many X100P compatible
in the market – some good and some not so good. The card I am using is the A100P
from Openvox. I have 4 of them ( one dead) and three have been working flawlessly for
the last 7 months.

This card allows you to connect a POTS (plain Old Telephone System) line to your
Asterisk box (See Notes if it does not install correctly).

OpenVox A100P Card

If this card is added after Asterisk has been configured, it may be necessary to configure
it by using the zaptel card auto-config utility so the correct zaptel driver will be set up. To
do that, enter the following from the command line.

rebuild_zaptel

Restart Asterisk

Shutdown –r now

After restart run the following:

genzaptelconf

Restart again.

Shutdown –r now

Next go into the freePBX web interface to create a trunk and you will notice that there is
already a trunk called ZAP/g0. You need to edit this.

1. Enter the phone number for you pots line in the Caller ID field
2. Enter 1 for Maximum channels
3. Set a dial rule you want for this trunk

TRIXBOX-2 Without Tears Page 79 of 224

 4. Select an outbound dial prefix to select this trunk when dialling
5. Set the Zap Identifier to 1 (the default is g0)

Once the card is configured, you must add a route for Incoming Calls or asterisk will not
answer this line

Click on Incoming Calls in freePBX and set up an incoming route. To make outbound
calls you will need to set an outbound route as well.

If you have this card installed, you may need to edit the following files (usually you don’t
have to); zapata.conf, zapata-auto.conf, zaptel.conf and modprobe.conf. The last 2
files live in the /etc directory – use a text editor (I use nano) to edit them as you cannot
edit them through Config Edit.

13.1.1 zapata.conf
Under [channels] add the following lines:
[channels]
busydetect=yes
busycount=6

The above is to ensure that the line is hung up if there is no answer or busy after 6
busy tones.

For my installation to function correctly, I have also changed the following setting to
obtain a good compromise on volume/echoing:

rxgain=4 (you may have to experiment a little with this setting)

txgain=2 (you may have to experiment a little with this setting)

13.1.2 zapata-auto.conf
Ensure the following exist in Zapata-auto.conf. It is located at the end of the file.

context=from-pstn
group=0
channel => 1

Leave the rest of the file as it is.

13.1.3 zaptel.conf
Change the loadzone and defaultzone to “au”

# Global data
loadzone = au
defaultzone = au

13.2 Digium TDM400P FXO/FXS Card

Like the Digium Wildcard X100P, this card allows you to connect a POTS (plain Old
Telephone System) line to your TRIXBOX© box. Unlike the X100P, this card has 4
module ports that can be loaded with FXS or FXO modules. Channel 1 is the top RJ-45
on the back of the TDM400P card.

If this card is installed after Asterisk has been loaded, you will need to configure it just like
the X100P by using the following command on the command line:

rebuild_zaptel

TRIXBOX-2 Without Tears Page 80 of 224

 Restart Asterisk

Shutdown –r now

After restart run the following;

genzaptelconf

Restart again.

Shutdown –r now

13.2.1 zapata-auto.conf
Next, using config edit, look in the zapata-auto.conf file and you will see a list of all
your channels in your TDM400P. Set up the trunks as trunks and the extensions as
extensions in freePBX.

When you open the Zapata-auto.conf file, it will look something like the illustration
below.

; Autogenerated by /usr/local/sbin/genzaptelconf -- do not hand edit

; Zaptel Channels Configurations (zapata.conf)
; This is not intended to be a complete zapata.conf. Rather, it is intended
; to be #include-d by /etc/zapata.conf that will include the global settings
;
callerid=asreceived
; Span 1: WCTDM/0 "Wildcard TDM400P REV E/F Board 1"
signalling=fxs_ks
; Note: this is a trunk. Create a ZAP trunk in AMP for Channel 1
context=from-pstn
group=0
channel => 1
; channel 2, WCTDM, inactive.
; channel 3, WCTDM, inactive.
; channel 4, WCTDM, inactive.

If in the illustration it shows channel 1 is your Zap extension then add a zap extension
for channel 1 in freePBX and if it shows your Zap trunk is channel 2 you should
create a zap trunk for channel 2 in freePBX.

Once this is done, reboot your PC and when Asterisk starts, use freePBX to add a
route for incoming calls or asterisk will not answer your trunk. Similarly, to make
outbound calls you will need an outbound route. Set them up as per setting up routes
in the earlier chapters of this document.

If you have this card installed, you may need to edit the following files: zapata.conf
and zaptel.conf as per the X100P card in the previous section.

13.2.2 modprobe.conf
You may need to edit the modprobe.conf to add the necessary option for usage in
Australia (in later versions of Trixbox© you don’t need to do this):

If exist, locate the line “install wctdm /sbin/ztcfg-- --ignore-install wctdm && /sbin/ztcfg” and edit it
to reflect the following:

install wctdm opermode=AUSTRALIA fxshonormode=1 boostringer=1 /sbin/ztcfg-- --ignore-install

wctdm && /sbin/ztcfg

TRIXBOX-2 Without Tears Page 81 of 224

 To ensure that you have the right mode operating, do the following at the command
line:

grep "AUTO FXO" /var/log/messages

You should see something like this:

Mar 10 13:30:09 asterisk1 kernel: Module 0: Installed -- AUTO FXO (AUSTRALIA mode)
Mar 10 13:30:09 asterisk1 kernel: Module 1: Installed -- AUTO FXO (AUSTRALIA mode)
Mar 10 13:30:09 asterisk1 kernel: Module 2: Installed -- AUTO FXO (AUSTRALIA mode)
Mar 10 13:30:09 asterisk1 kernel: Module 3: Installed -- AUTO FXO (AUSTRALIA mode)

If you see an FCC mode then you will have an impedance mismatch.

As of Zaptel Drivers 1.2.4, by selecting opermode=AUSTRALIA the zaptel drivers

automatically add the "boostringer=1, fxshonormode=1". Also see Appendix E.3
(Users Suggestions)

13.3 Caller ID (CID) using ZAP device

The illusive CID has been a talking point and hair pulling exercise for many users. It has
always been the case of “I have my ZAP trunk working fine but it is not sending the CID to
my Softphone or SIP Phone”.

The simple answers to this:

• In Australia, for you to get Caller ID is actually having to apply to your Telco to
have it activated on your line – this is not activated by default by your Telco
(Optus or Telstra). If caller ID is not activated on your line, you will not get CID.

• If you already have caller ID activated and still don’t get caller ID, it’s time to have
a look at the ZAP configuration file. Typically you may have to look at
zapata.conf and/or zapata-auto.conf.

Naturally if you are using an X100P clone for your FXO, the following exercise will
probably be futile as the X100P, even at the best of time will probably not handle the CID
properly. However if you are using a more substantial device such as the TDM400, then
this may possibly help you towards getting the CID passed correctly.

(caveat: This solution may not necessarily work for your installation but you have nothing to
loose if you try)

A participant (Shane B) in the Whirlpool Forum provided the solution below that will
correctly pass the CID to Asterisk and your telephones:

You may need to set the following switches in your zapata.conf and zapata-auto.conf.

13.3.1 zapata.conf

usecallingpres=yes
callwaitingcallerid=yes
threewaycalling=yes
usecallerid=yes
hidecallerid=no
relaxdtmf=yes

TRIXBOX-2 Without Tears Page 82 of 224

 13.3.2 zapata-auto.conf
The following switches may need to be added to the existing ones.

useincommingcalleridonzaptransfer=yes
adsi=yes
sendcalleridafter=2 ;you may need to add this switch

After the above are done, restart Trixbox:

Amportal restart

If you are lucky, it should work. If not, you haven’t really lost anything.

13.4 Sipura SPA3000 as a PSTN Interface

To those new to the SPA3000, there is a simplified installation and configuration
instruction by JMG Technology. While it is directed mainly at standalone ATA users, it
gives a good insight of the Sipura SPA3000’s capabilities.

I have come across a few people in the various forums wanting to use their Sipura SPA-
3000s as FXO front-end to their TRIXBOX© boxes. To help them in their endeavours,
I've put the following together, as no one single source of information that I've found so far
has a config that would actually work for me.

13.4.1 Log in to SPA3000

Login to your SPA-3000 as admin/advanced.

Before you change anything, I'd suggest taking a snapshot (i.e. just save the .html
page) of your current SPA-3000 configuration, just in case you ever need to refer
back to your own customisations.

If you're not already running the latest SPA-3000 firmware, then upgrade it to the
latest version (at the time of writing, it's 3.1.5a). Take another snapshot for good
measure. Nothing should have changed in your settings, except that you have a few
extra options that you didn't have before.

Now reset SPA-3000 back to factory defaults, because I'm only going to list the
minimum changes required to keep things simple. Take another snapshot now too, in
case you ever want to know what the defaults were.

Using method 1 above, it will be necessary for you to create an inbound route using
the 0298765432 (or whatever you have defined) as your inbound route DID number.
As this incoming call is identified by the (S0<:0298765432>) in the dial plan 1 setting
of your SPA3000, this can be directed to any extension by the inbound route.

Disconnect Tone setting of 425@-30,425@-30;1(.375/.375/1+2) work well for

Telstra, while 425@-30,425@-30;1(.390/.390/1+2) works better with Optus.

Using method 2 above, you are not required to create an inbound route as the call is
directed directly to asterisk and will be handled by the any DID / any CID catch all
inbound route. Through this route, you can direct it to your IVR or any extension you
like. This method is simpler if you only have one SPA3000, however if you are using
multiple SPA3000, method 1 is the recommended method.

13.4.4 SPA3000 as an outbound PSTN Trunk

To make PSTN calls using the SPA3000 you simply select the SPA3000 trunk, which
you have named Telstra (see trunk name that you have given to this trunk above) as the
first choice in your outbound route.

14 PSTN TO VOIP GATEWAY

If you are usingthe later versions of Trixbox©, the following instruction may not
apply as you can create DISA from FreePBX option without having to resort to
the manual configuration below – see DISA,

Now that the SPA-3000 has been set-up to accept PSTN, TRIXBOX© can be turned into
a PSTN to VOIP Gateway. You will not need a SPA-3000 if you have an FXO card
installed.

I need such a gateway because I often have to call overseas from my office. Needless to
say, we don’t make private overseas calls from the office phone. I overcame this by
calling my Asterisk box from the office and when it answered, I can then use asterisk to
call overseas.

I accomplished this through DISA – I have resorted to this manual method because in the
initial release of Trixbox© , DISA did not work, as I would like it to. This has since been
rectified

To do this, I manually edit the extensions_custom.conf, by adding the following entries

at the end of the file,

[custom-pstn2voip]
; I use this to call VOIP from PSTN
exten => s,1,Answer
exten => s,2,DigitTimeout(5)
exten => s,3,ResponseTimeout(10)
exten => s,4,Authenticate(my password)
exten => s,5,DISA(no-password|from-internal)

I have Digital Receptionist answers all incoming calls (refer to Digital Receptionist in the
previous section).

In the previous section I have 5 options in Digital receptionist e.g. Press 1 for Ben, 2 for
Rohani, and 3 for Norsurya. I did not announce the 4th option as I use it for DISA and is
only known to me, besides, it requires a password.

For option 4, I chose the radio button next to Custom App. In the custom app field I
entered custom-pstn2voip,s,1

Custom App custom-pstn2voip,s,1

When 4 is pressed, followed by the # key, during the announcement, the digital
receptionist will ask for a password. On entering the correct password, the one defined
in the example above, a dial tone will be heard. At this stage, you can start dialling the
number you wish to call.

Option 5, (which I have changes to the letter ‘t’, for timeout) is invoked if the caller does
not select any option or if the DTMF tone is not recognised. This option can be directed
to a Ring Group or to a human receptionist if you are using Asterisk in a business
environment.

TRIXBOX-2 Without Tears Page 87 of 224

15 DISA
15.1 DISA - Hand Coding Method
I use this function in my PSTN to VOIP gateway above.

DISA (Direct Inward System Access) allows you to dial in from outside to the Asterisk
switch (PBX) to obtain an "internal" system dial tone. You can place calls from it as if
they were placed from within.

Normally you can do this via the Digital Receptionist and enter the unannounced option
number known only to selected callers.

The caller enters his/her password, followed by the pound sign (#). If the password is
correct, the user is then given system dial tone on which an external call may be placed.

This type of access has SERIOUS security implications, and GREAT care must be taken
NOT to compromise your security.

The example below is how I have implemented my DISA.

In my "MyMenu" that says, “Hi, you have reached the Sharif’s household. Press 1 for
Ben, 2 for Rohani, 3 for Norsurya etc…” I have created an extra option – option 4 (best if
you use a few digits) that has an "Action" of "Custom App", which reads, "custom-
pstn2voip,s,1".

Then in extensions_custom.conf, I have added (do this towards the end of the file).

[custom-pstn2voip] < -- you can name it to whatever you like

exten => s,1,Answer
exten => s,2,DigitTimeout(5)
exten => s,3,ResponseTimeout(10)
exten => s,4,Authenticate(12345678)
exten => s,5,DISA(no-password|from-internal)

Change "12345678" to whatever digits you want your "DISA password" to be.

The above is one way of doing it (the hard way). The easier way of doing it is through
freePBX - see below.

TRIXBOX-2 Without Tears Page 88 of 224

 15.2 DISA – Using freePBX
Those using Trixbox© with freePBX as the User Interface will be able to configure DISA
from freePBX without having to do the above manual configuration. The same thing can
be achieved through freePBX as illustrated in the screenshot below.

I have populated the various fields thus:

• DISA name: PSTNVoIP (This is the name I gave to this application)

• PIN: 1234 (or whatever you think is appropriate. This pin number will be asked
when you want to use this service)
• Response Timeout: 10 (time needed for a response from the you in seconds)
• Digit Timeout: 5

The rest you can leave at the default value.

When you set up your digital receptionist, in the DISA dropdown selection, simply select
PSTNtoVOIP as your DISA application.

If you are using this method, there is a slight catch. When you choose the DISA option to
call a number, you will be greeted with “Please enter your password followed by the
pound key” and immediately you will get a dialtone. You may start dialling the password
followed by # followed by the telephone number.

E.g. If you have chosen to have a password e.g. 12345, and the number you wish to dial
is 0292345678, you must dial the number thus: 12345#0292345678 without waiting for
another dialtone, otherwise it will not dial out correctly and you will be wondering what
happened. I hope this will be fixed up soon.

This is the only screen that is required to be

filled in.

These are the only information required:

Account: <enter the extension number e.g.
2001>

Password: 2001 (I use the same number as

password for simplicity. I use the same
password when I set up the extension in
Asterisk).

Domain/Realm: <leave it blank>

Proxy: Your Asterisk network address e.g. 192.168.1.100
Port: 5060

Check the Auto Login and Keep Password.

Then click OK.

Audio & Video Tab

Next Click on the Audio & Video Tab to ensure

that audio properties set is consistent with the
Audio card installed in your PC/Notebook.

The illustration above depicts the sound device installed in my Notebook.

TRIXBOX-2 Without Tears Page 90 of 224

 • Click on the Tuning Wizard to tune your audio input and output.
• Check Auto Send Video (if you are using Video). I checked it anyway.
• Check Auto Receive Video (if you are using Video). I checked it anyway.

Click OK

Network Tab

Ensure that your Internet Connection Type is

set to LAN.

You may ignore the Information of Network

field.

Click OK

STUN Tab

You may or may not need to use a STUN

server. If you need to use it, click on the
STUN tab and enter the STUN server you
want to use. If you do, a list of publicly
available STUN server is listed in the section
referring to STUN Servers later in this
document.

In my case, I do not use STUN and therefore I left that section blank and Enable STUN
check box un-ticked.

Click OK to close.

Call Forward
This is pretty simple to set-up. To forward an unanswered call to this extension, all
you need to do is click on the Call Forward tab and enter the telephone number you
want to forward your incoming calls to. You have 3 options of call forwarding –
Always, On Busy or On No Answer. However this facility is only available if your PC
is on and the softphone is active.

Click OK when done.

You might want to set-up a couple of PCs with the softphone after which you may start
testing your brand new Phone System by dialling each extension in turn.

If you use one of the softphone and dial 7777, Asterisk will simulate an incoming call.

Once done, you may test your softphone connection to Asterisk.

17 OPERATOR PANEL
Operator Panel is a switchboard type application for the Asterisk PBX. Typically, it runs
on a web browser. It is able to display information about your PBX activity in real time.

The Flash Operator Panel is the one that comes with TRIXBOX©.

Apart from Flash Operator Panel, There are a number of operator panels available. One
that comes to mind can be found at SOFTPEDIA and another is HUDLite from Fonality.
HUD will integrate nicely with TRIXBOX© and the support for HUD is already integrated
within TRIXBOX©.

17.1 Flash Operator Panel (FOP)

This is the standard Operator Panel that is already part of TRIXBOX© – some loved it
while some hated it.

The layout is configurable (button sizes and colours, icons, etc). You can have more than
100 buttons active per screen. It also supports contexts: you can have one server
running and many different client displays (for hosted PBX, different departments, etc).

It can integrate with CRM software, by popping up a web page (and passing the CLID)
when a specified button is ringing.

FOP can be activated either from within freePBX by clicking on the Panel tab on the top
of the freePBX screen or from TRIXBOX© User Mode Welcome screen.

TRIXBOX-2 Without Tears Page 92 of 224

 The following information are displayed on FOP:

• Which extensions are busy, ringing or available

• Who is talking and to whom (CLID, context, priority)
• SIP and IAX registration status and reachability
• Meetme room status (number of participants)
• Queue status (number of users waiting)
• Message Waiting Indicator and count
• Parked channels
• Logged in Agents

Functions you can perform on FOP:

• Hang-up a channel
• Using drag-&-drop to transfer a call
• Initiate calls by drag-&-drop
• Barge in on a call using drag-&-drop
• Set the caller id when transferring or originating a call
• Automatically pop up web page with customer details
• Click-to-Dial from a web page
• Mute/Unmute meet-me participants

For more details refer to: http://www.asternic.org/

17.1.1 Setting the Admin Password

It is recommended to change the FOP password to something easy and simple to
remember such as the number 2 for example. The simple method is by logging in to
your asterisk box either remotely using putty or directly on your box console.

In this example, Putty is used to log in remotely to TRIXBOX© . Once logged in,
change the directory to /var/www/html/panel

cd /var/www/html/panel

Using nano as the editor, open the configuration file op_server.cfg

nano op_server.cfg

Go to the line that says security code=passw0rd

(in FOP that comes with TRIXBOX© , the default password is “passw0rd”)

Replace the “passw0rd” with the password of your choice.

security_code=cowscomehome

Close off nano and putty. Open your web browser and go to FOP. You should now
be able to click on the little lock, put in your password and you will see it lock up. Now
you can begin to have some fun.

17.1.2 Hang-up a Call

You can end a call by clicking the big red button.

17.1.3 Transfer a Call

Simply drag the little telephone over to the new extension and it will transfer the call.

TRIXBOX-2 Without Tears Page 93 of 224

 17.1.4 Initiate a Call
If you are lazy, like me, not bothered to pick up the phone and dial, you can drag and
drop your little telephone to another extension it will start by ringing your phone, when
you pick up and then it will ring the other extension. Once the destination phone is
picked up it will initiate the call.

17.1.5 Barge in or Create a Conference

Say there is a call already going and you want to jump in. Well all you have to do is
grab your little phone in the flash panel and drop it into the conversation and it will
connect you. Great if you want to see if your employees are making lots of private
calls.

17.2 HUDLite
HUDLite from Fonality integrates very nicely with Trixbox© and the HUD manager is
already incorporated in Trixbox©. It has most of the necessary functionalities (if not all) of
a modern operator switch panel where you can handle such tasks as:

• Answer Calls
• Transfer calls
• Hang up calls
• Put calls on hold etc.
• Monitor status of extensions just like the default FOP that comes with TRIXBOX©
and more.

To install HUDLite server, you must log in to Package (Trixbox Packages Tab) and select
to install HUDLite server from the Package Manager.

Once that is installed, you may proceed to set up HUDLite Admin.

17.2.1 Setting up HUDLite Admin

To set up HUDLite Admin, you will need to mouse ove the Asterisk Tab and select
HUDlite Admin selection from the dropdown menu as shown below.

When clicked with the mouse, you will be presented with the following screen where
you may populate it with new devices..

TRIXBOX-2 Without Tears Page 94 of 224

 Click on HUDlite Admin to populate it.

You will be presented with the screen as illustrated below.

To populate the HUDlite Admin, click on New device and the manage device fields
will be expanded. This is where you enter the credentials of the extensions that you
want to register with HUD Manager.

In the manage device fields I have entered the following:

Device: SIP2001 (the device for my extension)

Ext: 2001 (my extension)
Name: Ben Sharif (that’s my name if you don’t know)
Username: 2001 (that’s the extension ID)
Password: 2001 (I like it real simple)

The other three fields are not mandatory and you can leave them blank.

Click save.

If you have more extensions to register, click on New device again and repeat this
process as many extensions as you have.

Once this is done, you may proceed to install HUDLite.

TRIXBOX-2 Without Tears Page 95 of 224

 17.2.2 Setting Up HUDLite

After downloading, simply click on the EXE file and HudLite will be installed in your
Windows XP machine. Select the Typical setup option.

Once installed, run HUDLite you will be prompted to enter your Username and
Password:

Enter your username and password as required. I would enter one of my extension
number here and the extension password.

In my case I use my main office extension 2000.

Username: 2000
Password: 2000

Click Next

Next you will be asked for the server details. This is your TRIXBOX© credentials.
However in the password field, don’t use your server password, instead use HUDLite
default password of password.

In the Server name I entered my Trixbox IP address: 192.168.1.100

Server password, I simply use the default password: password.

TRIXBOX-2 Without Tears Page 96 of 224

 (I strongly urge that you use the default password for this initial installation. You can change
it later when you are more comfortable with tinkering around)

Then click Finish.

HUDLite will now start. Initially you will see just a blank hudlite screen like the
illustration below, as it will take a few seconds for it to gather some details.

After a few seconds, it will populate all the extensions that you have added in the
HUD Manager.

TRIXBOX-2 Without Tears Page 97 of 224

 If any of the extension is being called or making a call, you will see it highlighted just
like the main office extension on the top left corner (the main number rang as I was
capturing the illustration).

17.2.3 What if it does not work?

If after following the above instruction, and it does not work, make sure that you have
the correct values in the setup above.

Click on File -> Setting on the HUDLite screen, expand the Advanced setting and
make sure that the fields are correctly set as the set-up instructions above.

Username: 2000 (you may have different extension)

Password: 2000 (you may have different password)
Server Name: 192.168.1.100 (your Trixbox IP may be different from mine)
Server Password: password (it must be password)

Leave the other 3 fields at the default value.

The default password for HUD admin is password.

18 CALL PARKING AND TRANSFER
Trixbox© provides this facility through the Parking Lot facility of freePBX. If you want to
allocate other extensions rather than the one pre-configured, simply change the
appropriate Parking Lot extension number in the configuration screen. For this purpose
we will leave it at the default extension number 70.

18.1 Call Transfer - Managed

The definition of this facility is found in parking_additional.inc and it contains the
following lines:

parking_additional.inc

;*** WARNING: DO NOT HAND EDIT THIS FILE IT IS AUTO-GENERATD ***

;
parkext => 70 ; What ext. to dial to park

TRIXBOX-2 Without Tears Page 99 of 224

 parkpos => 71-79 ; What extensions to park calls on
context => parkedcalls ; Which context parked calls are in
parkingtime => 60 ; Number of seconds a call can be
; parked for (default is 45 seconds)

The above script is being called from feature.conf.

;
; Sample Parking configuration
;
[general]

; do not manually enter parkinglot config information, use the parkinglot module
;
; the parking_additional.inc file is auto-generated by the Parkinglot Module, do
; not hand edit that file

#include parking_additional.inc
#include features_general_custom.conf

[applicationmap]
#include features_applicationmap_additional.conf

; *** IMPORTANT NOTE ***

; The original blindxfer was '#', and has been changed to '##' to avoid
; issues with sending DTMF '#' to remote parties.

[featuremap]
blindxfer => ## ; Blind Transfer
disconnect => ** ; Disconnect Call
automon => *1 ; One Touch Record
;atxfer => *2 ; Attended Xfer

The following are other options that you can include in the general section of
features.conf if necessary.

transferdigittimeout =>3 ; Number of seconds to wait between digits

; when transferring a call (in seconds)
courtesytone = beep ; Sound file to play to the parked caller
; when someone dials a parked call

xfersound = beep ; to indicate an attended transfer is complete

xferfailsound = beeperr ; to indicate a failed transfer
;adsipark = yes ; if you want ADSI parking announcements
;pickupexten = *8 ; Configure the pickup extension. Default is *8
featuredigittimeout = 800 ; Max time (ms) between digits for
; feature activation. Default is 500

Each call parked will be parked at that extension +1 e.g. if you have 3 calls that you need
to park, the first call parked will be parked at ext. 71, the next call will be automatically
allocated ext. 72 and the next ext. 73 and so on.

This is handy if you want to manage the calls to be transfer. After parking the call, you
may call the person you are transferring it to and tell him/her that there is a call on
extension 71. The person can then dial 71 and get the parked call.

18.1.1 How is it done?

When you answer a call and want to transfer that call, do the following:

TRIXBOX-2 Without Tears Page 100 of 224

 1. Dial ##70 - the call will be transferred to a park extension and the number
will be announced to you. In this case it will be 71. After the announcement,
you may hang up and dial the extension of the person you wish to transfer
the call to and inform him to dial 71 to accept the call.

2. While all this is happening, the caller will be listening to the music on hold.

3. If for any reason the person refused to take the call, you then hang up and
dial 71 to pick up the call back to you and speak to the caller making the
usual excuses “I am afraid Mrs. Roberts, Dr. Roberts is busy with his nurse and
his office door is being locked from the inside” ☺ and the next time Dr. Roberts
will always accept the calls from his wife.

18.2 Call Transfer – Blind

To do a blind call transfer (where you simply transfer the call and bad luck if the extension
does not answer), you simply dial ## followed by the extension that the call is meant for.

E.g. to transfer to extension 2001, you simply dial ##2001 and hang up.

18.3 Put a Call On Hold

Just like the managed call transfer above, you dial ##70 and after the parked extension
announcement, you hang up. This is simply a work around for those that do not have the
hold function on the telephone.

When you are ready to take the call, dial 71 (or whatever the park extension is) and the
call will be picked up again. While the call is being parked, the caller will be listening to
your MOH music.

18.4 Call Pickup

Call Pickup is the ability to pick up a call on a phone that is ringing from other than the
ringing phone. E.g. you are sitting at your desk and the phone in the next office is ringing
but there is no one there to answer the phone. You then use the phone on your desk to
pick up the call.

There are two type of call pickups:-

• Group call pickup
This allows you to pickup a call from any ringing phone that is in the same pickup
group as you. However, if there were more than one phone ringing, you would
have no control over which call will be transferred to you.
• Directed pickup
This allows you to pickup a call that was made to a specific extension, such as
when you are in another office and a phone rings in the general direction of your
office. You are wondering if it is your phone that is ringing. In this case you
simply dial the pickup number and your extension number. If the ringing phone is
your phone, the call will be transferred to you.

Group call pickup is typically invoked by dialling ** from another phone in the call pickup
group.

You can also change to *8 or to something else if you wish.

see http://www.voip-info.org/wiki/view/Asterisk+config+features.conf

TRIXBOX-2 Without Tears Page 101 of 224

 18.5 Filter Your Incoming Calls - Only Accept Known Calls
(Good for filtering Telemarketers and ex-girlfriends)

For this purpose, the Privacy Manager option of the extension can be invoked, however I
found that caller often get confused with the need to enter the 10 digits phone number as
often they may have only 9 digits or more than 10 digits.

I have opted for the Nerd Vittles method.

There is a good article on this site http://mundy.org/blog/index.php?p=66 relating to filtering

incoming calls and also some discussions here http://forums.whirlpool.net.au/forum-
replies.cfm?t=418909

This feature will force callers to record their names before the calls will be parked. The
extension that you nominate will ring and on answering, you will be informed that there is
a call waiting for you in a parked extension e.g. 71.

After receiving the call and if you wish to take the call, hang up and dial 71 and you will be
connected to the caller. Otherwise, just hang up and the caller will just have to leave a
message in the voicemail. Real nifty ☺

This is how I did it with my Asterisk. Since I am pretty simple myself, I just take the low
road make it really simple.

I add the following scripts in my extensions_custom.conf

[from-internal-custom]

; I create this extension for silent Auto attendant 30-10-2005

exten => 111,1,Answer ;
exten => 111,2,Goto(who-r-u,s,1)

(Note: DO NOT create extension 111 in freePBX. This is only a

dummy extension)

At the end of the extensions_custom.conf, I added the following 2 blocks of extra

codes.

; experimental as per above 30-10-2005

[who-r-u]
exten => s,1,Background(privacy-unident)
exten => s,2,Background(vm-rec-name)
exten => s,3,Wait(2)
exten => s,4,Record(/tmp/asterisk-stranger:gsm|5|15)
exten => s,5,Background(pls-hold-while-try)
exten => s,6,Goto(parkedcalls,70,1)
exten => s,7,VoiceMail(2001@default)
exten => s,8,Playback(Goodbye)
exten => s,9,Hangup

[parkedcalls]
exten => 70,1,Answer
exten => 70,2,SetMusicOnHold(default)
exten => 70,3,ParkAndAnnounce(asterisk-friend:/tmp/asterisk-
stranger:vm-isonphone:at-following-
number:PARKED|40|local/2001@from-internal|who-r-u,s,7)
exten => 70,4,Hangup

(*The codes in red must be in one continuous line)

TRIXBOX-2 Without Tears Page 102 of 224

 I forward all calls that were parked to my existing extension 2001 (in bold type) and direct
voicemail for unanswered calls to the same extension as well.

Next I create a new extension using freePBX e.g. 222. Using a softphone, I connect to
extension 222 and unconditionally forward all calls to extension 222 to extension 111 by
dialling *72111

I then direct all my incoming calls from my PSTN trunk to extension 222.

The result is, when there is an oncoming call from PSTN, the call will be sent to extension
222 and in turn, the call will be forwarded to extension 111.

When the call gets to extension 111, the caller will hear a message saying that,
“unrecognised calls are not accepted and asking the caller to record his/her name after the tone”
(or something to that effect). After the caller has complied and press the # key, the call
will be parked.

Extension 2001 will be called by Asterisk. When you answer the call, Asterisk will
announce that there is a call by <name as recorded> on extension 71 (or 72 depending on
how many calls are being parked). If you recognize the name recorded, or if you want to
take the call, simply hang up and dial 71. You will be connected to the caller. While this
is all happening, the caller will be put on hold listening to your MOH.

If however you do not wish to accept the call, you simply hang up and do not dial 71. The
caller will be asked to leave a message instead.

19 CONFERENCE
Tele-conference can be configured through FreePBX Conference option.

Conference is pretty easy to set up, as there is very little to do. However, to set up
Conference, a Zaptel card may be required (at least in my case as I don’t seem to be able
to get it working without a Zaptel card installed). In the latest Trixbox 2, this seems to
have been resolved.

The Conference function of Asterisk is similar to a Tele-conference call where multiple

callers can call in and participate in a two-way conference like in a party room where
everyone can talk and listen to one another or just to listen to a Tele-presentation.

In Trixbox, there are 2 .conf files that relates to conferencing. They are:

meetme.conf
meetme_additional.conf

meetme.conf
Ensure that you have the following 2 lines (only 2 lines in the file):

[rooms]
#include meetme_additional.conf

All these lines do is point to the meetme_additional.conf where the conference

room extensions are being created when you create a conference room through
freePBX conference setup option.

meetme_additional.conf
This is where the extensions for the meeting rooms are created. One line per room.
You may have just one extension for your meeting room or you may have several
meeting rooms. In my case, I have 1 meeting room and therefore my
meetme_additional.conf contains the following extension:

; Extensions for my meeting rooms

conf => 8200|

19.1 Create Conference

FreePBX allows you to create one or more conference room through the Setup ->
Conference screen. All you have to do is fill in the appropriate fields on the screen and
you are on your way to a voice conference.

Naturally there are some options that you may wish to have for the conference room.
They are entirely up to you. The main important things are for you to create the
conference room number and the conference name for you to know what that
conference room is for. The rest of the fields are optional.

Below is what my conference configuration page looks like:

TRIXBOX-2 Without Tears Page 104 of 224

 • This conference room number is 8000
• I call this conference room General
• Users are not required to enter a PIN number to join the conference.
• Admin PIN number is not required for the conference to wait for the leader to
conduct the conference.
• I don’t have a joining message greeting when someone joins the conference.
• I have No in the leader wait option for the conference to wait for the conference
chairman.
• I require a user count so I have Yes in the user count field.
• I need to be informed when a user join or leave the conference. I have Yes here.
• The music on hold is also flagged as Yes as I want music on while waiting.

Once these are done, from one of your phones dial, 8000 and you will be able to join the
conference.

You are now in the conference room and every time someone joins or leaves the
conference, it will also be announced.

To test this, go to another phone and also dial 8000. You should hear an announcement
(if you are listening on the first phone), indicating that someone has joined the
conference.

If there are 2 (or more) of you, you will be able to talk to each other. If one of you hangs
up, you will know about it.

TRIXBOX-2 Without Tears Page 105 of 224

 19.1.1 /var/spool/asterisk/meetme

It seems that in some installations, the meetme directory may be missing from the
/var/spool/asterisk (this has been rectified in the later ISOs).

If this is the case, It may be necessary for this directory to be created otherwise if you
have the user join/leave feature enabled, meetme will not function correctly.

If you have the need to create this directory, do the following at root command
prompt:

mkdir /var/spool/asterisk/meetme

then change the ownership of this directory

chown asterisk.asterisk /var/spool/asterisk/meetme

next you need to change the permission,

chmod 775 /var/spool/asterisk/meetme

19.2 Invalid Conference number

If you get this error, chances are, it is caused by not having a zaptel timing source. This
often happen when you have upgraded your kernel, but you haven't recompiled your
zaptel to suit.

Here is the quick fix compliment of Rob, our freePBX guru.

Log in to your Asterisk box as root, and at the command prompt, do the following:

cd /usr/src/zaptel
make install
/etc/init.d/zaptel stop
/etc/init.d/zaptel start

TRIXBOX-2 Without Tears Page 106 of 224

20 VOICEMAIL

If you have enabled voice mail when setting up your extension, and you hear a
stutter tone (not the normal dial tone) when you initially pick up your phone, it is
indicating to you that you have a voice mail waiting.

You must run setup-mail from the command line initially for Voice Mail and
Notification to work in Trixbox.

To enable voicemail on an extension simply "enable" it when you create the extensions
from the freePBX GUI. If you require email notification of your voicemail, you may enter
your email address in the email address field.

Click submit when done followed by the red bar on top of the scree.

20.1 Enabling Email Notification

Asterisk can send email to you informing you that you have voicemail waiting in your
mailbox. In fact it can even send you the voicemail itself in the form of a .wav file if you so
desire.

20.1.1 Installing sendmail

This is not always the case in every installation. If this happens to you, you may need to re-
install sendmail.

I have been having some problem to get mail notification to be sent to my email
address. I later discovered that sendmail needed to be installed for this function to
work (thanks Thunderbird1 for pointing this out to me). Sadly, this is not mentioned
anywhere and has caused me major grief.

To install sendmail with yam, you can do it on the Asterisk box itself or connect
through SSH (I use putty to connect), by logging in as root.

Do these commands at the command prompt:

yum install sendmail-cf

This installs the necessary files for configuration of the sendmail client. Select “y” for
yes when prompted and sendmail will be installed.

Next you will need to do a little editing. I use nano to edit, thus:

nano /etc/mail/sendmail.mc

Locate the following line:

dnl define(`SMART_HOST',`smtp.yourprovider')

and edit it as per the example below

define(`SMART_HOST',`smtp.yourprovider')

Replace ‘smtp.yourprovider’ with your real smtp provider e.g. ‘smtp.ozemail.com.au’

Then press CTRL-X, and type in Y, hit enter. You'll be asked for the file name you
want "File Name To Write: /etc/mail/sendmail.mc", and hit enter.

TRIXBOX-2 Without Tears Page 107 of 224

 Next, you will need to rebuild your /etc/mail/sendmail.cf file.

At the command prompt, do the following:

make -C /etc/mail

Once done, restart sendmail thus;

/etc/init.d/sendmail restart

You should now be able to have your voice mails sent to you via email.

The above instruction is also mentioned in this link:

http://sourceforge.net/forum/message.php?msg_id=3387743
and http://sourceforge.net/forum/message.php?msg_id=3432175

20.1.2 /etc/hosts
There is a couple of things that you will need to do otherwise your email, although
sent to the email address, your email host may not accept the email if you do not
have a valid DNS.

By default, your host will look like this:

# Do not remove the following line, or various programs

# that require network functionality will fail.
127.0.0.1 localhost
127.0.0.1 asterisk1.local

Your mail server will not accept this as a valid DNS. Therefore you will need to use
your valid Domain Name e.g. pbx.myasterisk.com. If you are like me, without a
valid Domain Name, you should obtain one through DynDNS.

Using Nano, you will need to edit your /etc/hosts file from command line to this:

# Do not remove the following line, or various programs

# that require network functionality will fail.
127.0.0.1 localhost
127.0.0.1 pbx.myasterisk.com asterisk1.local

You may use an editor (such as nano) to edit /etc/hosts file through CLI.

If you are using SipBroker or Pennytel, its best not to make this change
as describe above, as SipBroker and Pennytel will resolve your DNS name
as the local host address of 127.0.0.1 as defined in the hosts file and not
your actual external IP address. To overcome this I substitute my DNS
hostname with another valid DNS name such as yahoo.com (as I have an
account with Yahoo – not sure about the legality side of this though).

Refer to Notes for a kludge fix if you are experiencing difficulties.

Next, if you wish, you will need to customize your email notification message in
/etc/asterisk/vm_email.inc file and to include the actual IP address of your asterisk
PC. I have found that this is best done through a text editor (e.g. Nano) as AMP
tends loose the formatting character. In the later versions of Trixbox, this can be
done through Config Edit.

Once these are done, you will receive email notification of voicemail left in your
voicemail box.

You may start testing it and your email received will look something like this:

From: Family Health Centre Voicemail To: Ben Sharif

Ben Sharif,

There is a new voicemail in mailbox 201:

From: "Mary" <321>

Length: 0:20 seconds
Date: Friday, July 29, 2005 at 11:16:38 PM

Dial *98 to access your voicemail by phone.

 20.2 Use Postfix Instead of Sendmail
Another alternative to email notification is to use Postfix instead of Sendmail because
Sendmail is not as secure besides, using Postfix is a lot easier and it is more secure than
Sendmail.

If you wish to gi this path, it is strongly recommend you remove Sendmail and replace it
with Postfix, with only 2 easy commands:

rpm -e --nodeps sendmail

yum -y install postfix

Following this, edit your /etc/postfix/main.cf, (use nano and my smtp server is shown
below, but you should be using yours) and add:

relayhost = smtp.ozemail.com.au

Replace smtp.ozemail.com.au with your own smtp server. E.g. if your belong to OPTUS,
it should be:

relayhost = mail.optusnet.com.au

You should also edit /etc/asterisk/vm_general.inc and set the "serveremail" parameter to
your real email address. This is to avoid messages with invalid from-addresses floating
aimlessly in the Internet.

Then load Postfix.

service postfix reload

Postfix will now send all outgoing email to your ISP's mail server.

20.3 How to Retrieve Voicemail from External Phone

To call in and retrieve your voicemail from external phone is as easy as simply calling
your number and retrieve your voice mail. This can be done easily if you have IVR
enabled in your new TRIXBOX system.

This is how I do it (you may have been told of other different methods).

20.3.1 Method 1

1. Call my number and when the Digital Receptionist answers, I will dial my
extension number prefixing it with an *. E.g. My extension number is 2001,
so when the DR answers me, I will dial *2001

2. I will then be ask to leave a voicemail, but instead, I will dial * again.

3. DR will ask for a password to be followed by the # key.

4. I enter my password followed by #

5. DR will then give me my voice mail if there is any.

TRIXBOX-2 Without Tears Page 110 of 224

 20.3.2 Method 2

1. From freePBX Setup Screen, create a Misc Destination and give it a name
of e.g. “Check VM”
2. Select Feature Code Dial Voicemail (*98) from the dropdown menu.
3. Submit the changes.

Next modify your IVR

1. Increase option. If you already have 7 options, this will be the 8th.
2. Create an unannounced IVR selection e.g. selection no: 8
3. For this option, select Misc Destination and from the drop down, select
“Check VM”
4. Save and don’t forget to click on the red bar.
5. When you call your PBX from an external phone, DR will naturally ask you to
make a selection. Selection 8 will not be announced, however you should
select 8.
6. DR will ask for a mailbox number
7. Enter your extension number (which is also your mailbox number)
8. Dr will then ask for your password
9. And you will get your mailbox IVR prompt.

As I said, it is indeed simple.

20.4 How to Change Voice Mail Greetings

The default Voicemail greeting is fine but it is rather bland and quite boring. No doubt
some user would like to change the standard greeting to something more personal and
meaningful.

Ensure that you have changed your Direct Dial to Voicemail message type, in
General Setting, from Default to something else e.g. Unavailable. Otherwise
when you use follow-me and the like, your custom recorded message will not
be played back. The Asterisk default message will be played back instead.

To do so is pretty simple. Here are the steps:

1. Use your existing extension and dial *97

2. You will be asked for your password (if you have entered one)
3. When the Voicemail IVR starts, press 0
4. You will then be given the choice what type of message you want to record.
5. Choose the appropriate message you want to record.
6. Record your message “Thank you for calling, I am either busy elsewhere or on the
phone. Please leave me your message and I will call you back as soon as I can”.
7. Review your message
8. Re-record if you want to or if you are happy with the message, choose the option
to save.

That’s all – you are done.

21 FAX TO E-MAIL
Before setting up Fax over IP, I suggest that we should read this: http://www.soft-
switch.org/foip.html and : http://www.voip-info.org/wiki-Asterisk+fax

While sending and/or receiving Faxes is one of the available functions in TRIXBOX, there
have been reports of various degree of success. This is very much dependant on the
type of equipment used such as PC, processor speed, line quality etc.

In the earlier incarnation of TRIXBOX (it was AAH for those old enough to remember), for
the fax facility to work reliably, you will also need Newman Telecom’s NVfaxdetect. This
can be downloaded FREE. This may require some modification and recompiling.

SpanDSP allows Asterisk to receive faxes by converting the received data to .pdf format.
This service must be installed. If you want to have this function, you will need to install the
support for encoding incoming faxes as PDF. This support is not pre-installed with
TRIXBOX although the necessary files are there for you to manually install.

21.1 Installing Fax for TRIXBOX

Unlike previous versions of Trixbox/AAH where it has to be installed separately, the later
versions of Trixbox uses Asterisk version 1.2.2 where the developers of Asterisk have
included NVfaxdetect in Asterisk which allows incoming faxes to be received over SIP,
IAX & ZAP channel..

There has been mixed reactions on the ability of sending and receiving fax through
Trixbox as such I would suggest that, if you are relying on fax, to use a dedicated fax
machine and only use Trixbox for experimental purposes only (at this stage anyway).

Whatever it is worth, I have not been able to utilise this facility to my

satisfaction.

22 WEATHER REPORTS
The existing weather forecast information that comes with TRIXBOX is configured for
New York. However, Asterisk can be configured to allow the automatic downloading of
Australian weather forecast information, convert it to a .wav file and play the
announcement. The announcement will be a simulated announcement (ala Dr. Who’s
Dalek). However it will provide you with the weather report of your region of choice.

The Australia weather report reference file can be obtained from the following site:
http://www.bom.gov.au/

You may choose the reference file (text file) for the area that you are interested in. You
do not need to manually download the file, instead only the file name is required to be
noted and can be incorporated within the Trixbox’s extensions_trixbox.conf file later.
The script will download the file for you in the background.

The following are examples of available weather report files that you can reference in
your script.

Forecast Area File reference

NSW Sydney Metro IDN10064
All NSW IDN10031
ACT IDN10035
Snowy Mountain IDN10103
Brisbane Metro IDQ10090
All Queensland IDQ10700
Melbourne Metro IDV10450
All Victoria IDV10310
Adelaide Metro IDS10034
All SA IDS10033
Perth Metro IDW12300
All WA IDW12000
Darwin and Rural Area (All NT) IDD10110
Tasmanian Cities IDT13400
All Tasmania IDT13100

For a complete list, refer to the link below:

http://www.bom.gov.au/inside/cosb/stcm/idcodes/tables/current/vic_products.shtml

The following step-by-step instruction will guide you through.

22.1 Configure Weather Report – On Demand.

Some preparations need to be manually conducted through Linux Command Line, or if
you prefer, you may use Webmin.

I used Putty to log on to the Asterisk box remotely and used Nano to create a text file
called “convert2wav” in the /usr/bin directory containing the following:

/usr/bin/flite /tmp/weather.txt /tmp/weather.wav

(This command is used to convert the weather text file to a .wav sound file).

Once this is done, the permission for the “convert2wav” text file need to be appropriately
set to allow it to be executed. To do this you need to run the following command from
Command Line.

chmod 755 /usr/bin/convert2wav

TRIXBOX-2 Without Tears Page 113 of 224

 Now you have completed all the necessary preparations – for me anyway.

22.1.1 Create Extension codes.

The next step is to include the following in the extensions_trixbox.conf through the
Config Edit option of TRIXBOX Maintenance Tab. Select an unused extension code
e.g. *61, *63, *64 etc.

Add the following example (*Note: The third line in each section (bold) should read as a
complete single line- change the file reference in red to suit.).

; ##################################
; Forecast for Sydney Metro
; ###################################
exten => *61,1,Answer
exten => *61,2,Playback(national-weather-service)
exten => *61,3,Playback(pls-hold-while-try)
exten => *61,4,System(/usr/bin/wget -O weather.txt
ftp://ftp2.bom.gov.au/anon/gen/fwo/IDN10064.txt)
exten => *61,5,Wait(1)
exten => *61,6,System(/usr/bin/convert2wav)
exten => *61,7,Playback(/tmp/weather)
exten => *61,8,System(rm /tmp/weather.* -f)
exten => *61,9,Hangup

; ######################################
; Forecast for the whole of NSW
; ######################################
exten => *63,1,Answer
exten => *63,2,Playback(national-weather-service)
exten => *63,3,Playback(pls-hold-while-try)
exten => *63,4,System(/usr/bin/wget -O weather.txt
ftp://ftp2.bom.gov.au/anon/gen/fwo/IDN10031.txt)
exten => *63,5,Wait(1)
exten => *63,6,System(/usr/bin/convert2wav)
exten => *63,7,Playback(/tmp/weather)
exten => *63,8,System(rm /tmp/weather.* -f)
exten => *63,9,Hangup

Restart asterisk and test. You will be presented with the weather report of the areas
you have chosen.

(Source Reference:
http://forums.whirlpool.net.au/forum-replies.cfm?t=364420&p=1)

This method is very slow and therefore is only suitable for a very fast PC. Depending on
the speed of your computer during the .wav conversion, there may be about 1 minute or
more delay between dialling the extension and the weather announcement. Therefore I
have included step 3 telling the caller to hold while trying to connect.

Therefore, there has to be a better method – so read on.

22.2 Configure Weather Report – Background Method.

After giving it a bit of thought, I have decided to let Asterisk do the task of getting the
weather text files and converting them to the necessary sound files in the background
every 4 hours. This will cut down the waiting period when a caller chooses to listen to the
weather report.

TRIXBOX-2 Without Tears Page 114 of 224

 First we will use putty to make a batch text file called “convert2wav” in the /usr/bin
directory containing the following:

/usr/bin/wget -O /tmp/weather1.txt ftp://ftp2.bom.gov.au/anon/gen/fwo/IDN10064.txt

/usr/bin/flite /tmp/weather1.txt /tmp/weather1.wav
/usr/bin/wget -O /tmp/weather2.txt ftp://ftp2.bom.gov.au/anon/gen/fwo/IDN10031.txt
/usr/bin/flite /tmp/weather2.txt /tmp/weather2.wav

(Change IDN10064.txt and IDN10031.txt to suit the areas you require)

If you want to get rid of a couple of nasty characters, you can always add the following
line or lines in the appropriate places and changing the characters that you want to
discard or change,

# sed 's/\[/ /g' /tmp/weather1.txt > temp.txt

# sed 's/\]/ /g' /tmp/weather1.txt > temp.txt
# sed 's/\_/ /g' /tmp/weather1.txt > temp.txt
as an example

- but we are not going there. It may get too confusing. For the moment we will just stick
with the batch file example above.

Once this is done, change the permission for “convert2wav” thus:

chmod 755 /usr/bin/convert2wav

Use Webmin to schedule a Cron job to run this batch file every 4 hours (or schedule it to
suit your purpose). This will run the batch job at the scheduled time avoiding having to
download the weather file and converting them to sound files when a caller chooses the
weather report option.

The sound files will always be available when a caller requires them without having to
wait for them to be downloaded and converted.

22.2.1 Create Extension codes.

Next include the following in extensions_trixbox.conf. Select an unused extension

code e.g. *61, *63, *64 etc.

Add the following example

; ##################################
; Forecast for Sydney Metro
; ###################################

exten => *61,1,Answer

exten => *61,2,Playback(national-weather-service)
exten => *61,3,Playback(pls-hold-while-try)
exten => *61,4,Playback(/tmp/weather1)
exten => *61,5,Hangup

; ######################################
; Forecast for the whole of NSW
; ######################################

exten => *63,1,Answer

exten => *63,2,Playback(national-weather-service)
exten => *63,3,Playback(pls-hold-while-try)
exten => *63,4,Playback(/tmp/weather2)

TRIXBOX-2 Without Tears Page 115 of 224

 exten => *63,5,Hangup

Restart asterisk and test. You will be presented with the weather report of the areas
you have chosen without any delay whatsoever.

22.3 Now put it in your Digital Receptionist

If you want the 2 procedures to be incorporated in your Digital receptionist, simply
duplicate them in your extensions_custom.conf with some minor changes. You will
want the digital receptionist to know which weather report you are referring to when you
make the choice. Give it a label – see example below (the changes made are in bold).

; ##################################
; Forecast for Sydney Metro
; ###################################
[custom-weathermetro]
exten => s,1,Answer
exten => s,2,Playback(national-weather-service)
exten => s,3,Playback(pls-hold-while-try)
exten => s,4,Playback(/tmp/weather1)
exten => s,5,Hangup

; ######################################
; Forecast for the whole of NSW
; ######################################
[custom-weathernsw]
exten => s,1,Answer
exten => s,2,Playback(national-weather-service)
exten => s,3,Playback(pls-hold-while-try)
exten => s,4,Playback(/tmp/weather2)
exten => s,5,Hangup

When you create your menu option in Digital receptionist, e.g. “Press 6 for Sydney
weather report, press 7 for the whole of NSW weather report”, select the custom app: and
enter the appropriate custom procedures above. See example below:

Custom App custom-weathermetro,s,1

Custom App custom-weathernsw,s,1

23 REMOTE MANAGEMENT
Some may want to manage their Asterisk Box remotely. If you are thinking about doing
this, I highly recommend you register with Dyndns to get yourself a dynamic DNS unless
you have a fixed public IP address.

You should also forward port 80 on your router to point to the local IP address of your
Asterisk box.

To log on to your Asterisk box remotely using your browser, use

http://your_Dyndns_name:80 or http://your_public_ip_address:80

23.1 httpd.conf
If you are using Optus Cable, you may not be able to use port 80. However this can be
overcame by changing the port to 8080. To do this, you will be required to change one
setting in the httpd.conf file which resides in the /etc/httpd/conf directory.

If you are not a Linux fan, I suggest you use either webmin or putty to access the file. I
use Putty to log on remotely to the console and edit the file with Nano using the following
command.

nano /etc/httpd/conf/httpd.conf

In the file, look for the following entry (marked in red) - below :

# Change this to Listen on specific IP addresses as shown below to

# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
# e.g. "Listen 12.34.56.78:80"
#
# To allow connections to IPv6 addresses add "Listen [::]:80"
#
Listen 0.0.0.0:80 change this from 0.0.0.0:80 to read 0.0.0.0:8080
#

After doing the above, reboot Asterisk.

Don’t panic if you can no longer access AMP through you web browser. You simply
append: 8080 after the address e.g. 192.168.1.101:8080

24 HOW TO SET UP A REMOTE EXTENSION
If you carry your laptop/notebook everywhere you go, you may want to consider setting
up a remote extension on your Notebook. Basically its set up is similar to the softphone
that you set up on your other computers except that you should have a fixed IP address
for your Asterisk server or use DynDNS to register a Domain ID for your Asterisk box.

Since I am on Optusnet cable, I only have the privilege of a dynamic IP hence I registered
for a Domain ID with DynDNS pointing to my Dynamic IP address. Every time my
dynamic IP changes, DynDNS will point to the new IP address. This way I don’t have to
keep changing IP addresses. I simply use the same DNS ID eg: myasterisk.freedns.com

24.1 Create a new extension

Create a new IAX2 extension in Asterisk – just like the other extension that you created
before. This time instead of creating a SIP extension, create an IAX extension (you can
use SIP as well but since you don’t have any control of the external router that you may
be connected to when you are away from your own environment, IAX will avoid any NAT
issue that you may encounter). In your router, you will need to forward port 4569 to your
Asterisk Box.

As mentioned above, you may create a SIP extension instead, if you so wish but you
must ensure that you set “nat” field to “yes” ( in the device option) instead of “never” as
illustrated in the screen below - see red arrow.

TRIXBOX-2 Without Tears Page 118 of 224

 Once you have done this, you will need to ensure a couple of things in your .conf files are
set correctly.

24.2 IAX.Conf
The following is the content of my iax.conf file.

iax.conf
[general]
bindport = 4569 ; Port to bind to (IAX is 4569. Forward this port to your Asterisk box)
externip = <your fixed external IP> or
externhost = <myasterisk.freedns.com>
localnet = 192.168.1.0/255.255.255.0
bindaddr = 0.0.0.0 ; Address to bind to (all addresses on machine)
delayreject = yes
disallow=all
allow=g729
allow=ilbc
allow=gsm
allow=g723
allow=alaw
allow=ulaw

jitterbuffer = yes
mailboxdetail = yes

#include iax_additional.conf
#include iax_custom.conf

24.3 Sip_Nat.Conf
The only other .conf file that requires attention is the sip_nat.conf in case you want to
use SIP. If you do, ensure that you have forward ports 5004 – 5082 as well. My file is as
per the example below.

sip_nat.conf
nat=yes
externip=<your fixed external IP> or
externhost=< myasterisk.freedns.com> (see note)

TRIXBOX-2 Without Tears Page 119 of 224

 localnet=192.168.1.0/255.255.255.0
externrefresh=10

Those are the only 2 .conf files that require changing if needed.

24.4 Setting up an IAX Softphone

I use an IAX softphone called IDEFISK. You can get IDEFISK from here:
http://www.asteriskguru.com/tools/idefisk_beta.php

You can also use Virbiage softphone as it will handle IAX.

Setting up IDEFISK is very simple. All you have to do is download the file, extract it and
save it in its own directory.

Click on the idefisk.exe and just configure it like the example below.

Once the softphone is active, to start

configuring, simply place your curser
anywhere in the middle if the image and
right click.

The configuration option window will be

displayed.

24.4.1 First the general options

In the general options, checked the
“Check for update” and “Automatic
popup on incoming call” options.

The next option to take care of is the Account option. Apart from that, there is nothing
else critical to be done for you to use IDEFISK.

TRIXBOX-2 Without Tears Page 120 of 224

 24.4.2 Accounts options
Next click on the Account Options and set up your account as per the image below.

The rest of the options are there for you to set up your sound preference and customize
your look and feel. They are pretty straightforward.

Now you are ready to go on the road with an Asterisk extension under your arm.

TRIXBOX-2 Without Tears Page 121 of 224

25 CALLS RECORDINGS
There have been numerous discussions on the legality of recording telephone
conversations. Some say its OK while others say its illegal. If you are recording
conversation without the consent of all parties, you may be breaking the law – so be
warned.

For those who do record conversations, the recording are kept in the
/var/spool/asterisk/monitor directory or you can monitor the recording through the ARI
interface.

25.1 ARI Interface

The ARI interface can be access either from the User Mode screen of Trixbox or freePBX
GUI.

Use mode interface of Trixbox

FreePBX GUI of Trixbox

If you want to monitor all the calls, you will need to log in as admin with the default
password of ari_password.

TRIXBOX-2 Without Tears Page 122 of 224

 To monitor the calls for any individual extension, log in using the extension number and
the extension password.

To play the recording, simply click on the Play link related to the extension that you want
to listen to, in the screen that follows.

The configuration file for ARI is /var/www/html/recordings/includes/main.conf.php

There are 2 ways you can record your calls:

25.1 Record all calls by default

To record all calls, on a specific extensions or all extensions, this function has to be
enabled on the extension or extensions involved. This is done through the Extension
Options Record Incoming and Record Outgoing field by selecting “Always” from the
dropdown box for both fields.

25.2 Record calls on demand.

To record on demand, the caller or the receiver have to dial *1 when he/she need the
recording to start (Asterisk v1.2). This function will only work if the feature is enabled.

To enabled this feature, the following Dial Command Option must be enabled in freePBX
General settings Asterisk Dial command option and Asterisk Outbound Dial
command option fields by adding the following flag in the fields.

w: Allow the called user to start recording after pressing *1 (Asterisk v1.2)
W: Allow the calling user to start recording after pressing *1 (Asterisk v1.2)

Some users have noticed that the *1 need to be pressed very quickly for this feature to
work. This can be remedied by adding the following line in the features,conf file under
the general section.

featuredigittimeout = 1500 ;(the default is 500 which is too fast for an old guy like me

26 STUN SERVERS
STUN (Simple Traversal of UDP through NAT - Network Address Translation) is a
protocol for assisting devices behind a NAT firewall or router with their packet routing
operates on TCP and UDP port 3478.

I never have the need to use STUN. The list below is provided for those who have the
need to use public STUN Servers. These are the servers that I am aware off - there may
be others.

27 DIALING THROUGH MS OUTLOOK®

One way of keeping a little black book for all your telephone contacts is through
Microsoft™ Outlook® (for the windows users) address book. We can also use Outlook to
dial the phone numbers in the address book as Outlook® has a click-to-dial facility.

I was alerted of this facility in Outlook® and Asterisk® and asked to prove the application
and publish a simplified instruction in this guide.

27.1 Download AstTapi

Before you get started, you will need to download AstTapi, which is a Microsoft TAPI to
Asterisk Bridge. This little gem (still under further development at the moment but
functional) will make it possible to do click-to-dial from Microsoft™ Outlook and for that
matter from other TAPI compliant applications.

Download AstTapi from http://sourceforge.net/projects/asttapi/

To get started, you will need to edit manager_custom.conf file. The easiest is to use
freePBX Config Edit (the easiest way!)

SETUP -> Config Edit -> manager_custom.conf

On opening the manager_custom.conf file, you will notice the following, which you will
need to do a tiny weeny edit:

[phpconfig]
secret = php[onfig
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.0
read = system,call,log,verbose,command,agent,user
write = system,call,log,verbose,command,agent,user

[phpagi]
secret = phpagi
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.0
read = system,call,log,verbose,command,agent,user
write = system,call,log,verbose,command,agent,user

[AstTapi]
secret = AstTapi
deny=0.0.0.0/0.0.0.0

TRIXBOX-2 Without Tears Page 124 of 224

 #permit=192.168.1.0/255.255.255.0
read = system,call,log,verbose,command,agent,user
write = system,call,log,verbose,command,agent,user

Under the [AstTapi] User context, remove the # from the permit line and change the
192.168.1.0 to the network address of your network. In my case I left it as it is because
my network is under 192.168.1.0 (see red highlight).

Once this is done, click Update and restart Asterisk.

27.2 Install AstTapi

Install AstTapi on your PC – the one that you have Microsoft Outlook installed. Follow the
prompt and once completed you will need to restart your PC for the new driver to take
effect.

27.3 Configure Outlook Address Book

Fire up Outlook®.

Click on Contacts from your

folder list.

Select a contact that you

want to call (provided that a
telephone number has been
recorded).

Click on the phone icon.

Click on the Telephone icon.

The New Call dialog box will

be displayed:

Select Dialling Options.

TRIXBOX-2 Without Tears Page 125 of 224

 The Dialling Option box will
be displayed.

In the "connect using line"

drop down box, select
Asterisk.

Then click on Line

properties.

In the Host field, enter the

address of your asterisk
server: e.g. 192.168.1.100

In the Port Field: 5038

User Field: AstTapi

User Channel: (your extension – the extension you want Asterisk to ring before
connecting you the number you are calling) e.g. sip/2001

Select dial by context radio button.

Enter outbound-allroutes in the context box

When done, click Apply and you are done.

You can now start making calls from Outlook using the click-to-dial facility.

Now… that was quite painless.

28 SPEED DIAL
Sometime you may just need to call someone quickly without having to look up his/her
phone number. Well, you can by simply defining a shortcut number. There are 2 ways
you can do this - my way and Trixbox’s way.

28.1 The Dumb-Me method

Since I am very bad at remembering phone numbers – I cant remember my own phone
number (or my car registration number), I have defined some shortcut numbers for my
family using the first 3 characters of their first names e.g. Adam is ADA which translate to
232 on the telephone keypad. Make sure the numbers have not been allocated to your
local extension.

To do this, you will need to edit extensions_custom.conf by adding the lines below
containing the relevant exten expressions.

You can do this through Setup -> Config Edit

; #############################################################
; Speed Dial to some predefined numbers (added by Ben 2/12/2005)
; #############################################################

exten => 236,1,Dial(SIP/6140036xxxx@pennytelsip,60,m) ; Ben’s Mobile

exten => 236,n,Hangup

exten => 764,1,Dial(SIP/6141242xxxx@pennytelsip,60,m) ; Rohani’s Mobile

exten => 764,n,Hangup

exten => 667,1,Dial(SIP/6140470xxxx@pennytelsip,60,m) ; Nor’s Mobile

exten => 667,n,Hangup

exten => 767,1,Dial(SIP/6140512xxxx@pennytelsip,60,m) ; Ros’s Mobile

exten => 767,n,Hangup

exten => 232,1,Dial(SIP/6140936xxxx@pennytelsip,60,m) ; Adam’s Mobile

exten => 232,n,Hangup

You will need to substitute the example phone numbers above such as 6140036xxxx with
the real phone numbers.

When 236 (which is BEN) is dialled, you will hear a voice prompt saying “Please wait
while I connect your call” followed by Asterisk calling Ben’s Mobile number which is
61400336510 using the Pennytel SIP trunk.

Pennytel SIP trunk was called Pennytelsip when it was initially set up.

The call will be tried for 60 seconds (,60) and while the call is being attempted, the caller
will be listening to a MOH tune (,m) instead of the ringing tone. You may however
change it to a ringing tone by substituting the “m” with a “r” or remove “,m” altogether

Once you have done that, click on Update and re-read the config. That’s all there is to it.

 28.2 TRIXBOX’s method (Version 1.x)
In Trixbox v1.x, there is however, a simpler way (Later versions have different method)
which I will cover after this.

TRIXBOX has included a built-in speed dialling utility amongst the goodies that comes
with it. Numbers 300 to 399 has been reserved for this purpose.

To add a number to your speed dial list, you simply pick up one of your extensions and
punch in 3003XX61212345680 (assuming 61212345680 is the number you want to save
in your speed dial list) where 3XX is the speed dial code for 61212345680 (substitute 3XX
for the position e.g. 301).

After doing that, Asterisk will confirm the code and the number that you have just
registered. If you want to make correction to or change the telephone number that you
have entered simply repeat the process.

In the above example, every time you dial 301 Asterisk will dial out the number
associated with that code. In this case, it is 61212345680.

Ensure that you enter the number to be called in the same format that is supported by
your Asterisk dialplan.

To look up speed dial numbers, simply dial * followed by the 3-digit speed dial code, e.g.
*301. This will tell you the number stored in speed dial position 301.

28.3 TRIXBOX’s method (Version 2.x)

In Trixbox v2.x, the method in version 1.x has been revised to use the Asterisk Phone
Book found under the TOOLS Tab.

Here you simply enter the Phone number of the party you wish to call, the name and the
Speed Dial Code in the appropriate fields as per the example below. Submit change
when done.

To call the Speed dial, e.g. you want to call Ben Sharif, simply dial *069 (the *0 tells
Trixbox that you want to use the Speed Dial and the 69 is the Speed Dial Code for Ben
Sharif).

The Speed Dial Prefix *0 can be found under Feature Codes.

Naturally if you have a big list of Names and Phone Numbers that you want to enter in
your Trixbox Phone Book, you have the option of uploading the list. You have to scroll

TRIXBOX-2 Without Tears Page 128 of 224

 down the page to get to the “Import from CSV” section of the Phone Book (see illustration
below)
.

The “Import from CSV” is a misnomer because, if you havae created a list using EXCEL
and trying to import the list, it will not work since EXCEL CSV file is a comma delimited
one where as freePBX is expecting a semi-colon delimited file. Mousing over the word
file will give you the format it is expecting;

“Name”;Number;Speeddial code

Ensure that “Name” must be enclosed in quotation marks.

Any speeddial code that already exist in the phone book cannot be reused. If you want to
use an existing speeddial code in your so called “CSV” file, the existing entry in the phone
book must first be removed.

29 HOW TO USE WINDOW MESSENGER® 5.X

Windows Messenger is NOT MSN Messenger. You may need to download

Windows Messenger from Microsoft.

Set up Windows Messenger 5.x as a SIP client on your PC:

1. Start Windows Messenger from your PC.

From the Windows Messenger dialog box, go to Tools -> Options ->Accounts:

• Check the [My contacts include users of a SIP Communications Service] checkbox.
• Enter "sip:<your extension>@<Asterisk Address>"
(e.g.."sip:206@192.168.1.101") in the [Sign-in name] field

2. Click on the [Advanced] button next to the Sign-in name.

• Check the [Configure settings] button

• Enter Asterisk IP address (e.g.192.168.1.101) in the [Server name of IP address]
field
• Check the [UDP] button
• Click [OK] and [OK] again.

In order for Windows Messenger to work as a voice communication device, you must
have a microphone and speaker(s) connected to your PC.

TRIXBOX-2 Without Tears Page 130 of 224

 This setting means the Windows Messenger has a user/phone number of 206
known to the SIP server (your Asterisk box) of 192.168.1.101.

Verify that Windows Messenger has successfully registered with Asterisk by logging in to
Asterisk.

freePBX -> Tools -> Asterisk Information. – this is available as an addon (see NOTES
on Adding the missing Maintenance Modules)

You should see under SIP Registry that the Windows Messenger is registered as a
user/phone number of 206, with a contact URL of your local PC IP Address e.g.
192.168.0.11, among other registration information.

Note: Windows Messenger 5.0 or later has support for VoIP communications but it seems
that it may create problems with chat or other features. For this purpose, please focus
your testing on VoIP only.

30 HOW TO INTERCONNECT 2 BOXES
There may be a time when you want to interconnect 2 Asterisks boxes (def.com.au and
xyz.com.au) together and if you are like me, you will probably be spending a good part of
3 hours trying to get them to talk to one another.

I have 2 different locations, the Main Office (def.com.au) with about 11 extensions and
another office in a different location (xyz.com.au) about 20 km away with 9 extensions.
The main office is the only box that will have accounts with different VSPs and all external
communications are through the main office Asterisk box. I settled for the simplest
solution and after some fiddling around I managed to get them to work the way I wanted it
but not happy with it, I solicited some advise from a friend (thanks to Mark Brooker) who
provided further assistance.

Instead of being verbose in my explanation, I will just create a few tables outlining what I
did. I hope this will help those in the same position as I am, to set 2 very basic systems
together (you can refer to DUNDi for a more complete solution). A little tutorial on DUNDi
can be found here.

30.1 Method 1 - With the Peer Asterisk box as Extensions

For the purpose of registering the peers to each other, I created 1 extension on each box
eg: 90000 on System 1 and 91000 on System 2– using extension numbers that I am not
likely to use as local extensions (while some users have had success using common
extension, but I prefer 2 separate extensions as I have them working). For simplicity, I
gave a common password xxxyyy to both boxes. Avoid using extension starting with 8 as
it may clash with conferencing.

System 1 System 2
def.com.au xyz.com.au
IAX Trunk
Outgoing Dial Rules: XX. XX.
Trunk Name Parramatta MainOffice
host=xyz.com.au (or System 2 IP) host=def.com.au (or System 1 IP)
Peer Details secret=xxxyyy secret=xxxyyy
type=peer type=peer
username=91000 username=90000
User Context Leave blank Leave blank
User Details Leave blank Leave blank
Register String 91000:xxxyyy@xyz.com.au 90000:xxxyyy@def.com.au
Note: Registration isn’t really necessary. It will still work without it unless you use Dynamic IP.

System 1 System 2

Extensions
Phone Protocol IAX IAX
Extension Number 90000 91000
Extension Password xxxyyy xxxyyy

TRIXBOX-2 Without Tears Page 132 of 224

 System 1 System 2

6XXX XX.
Dial Patterns (6001 to 6009 are Parramatta (Apart from Local extensions, all
Office extensions) others go via Main Office)
Trunk Sequence IAX2/Parramatta IAX2/MainOffice

The above Outbound Routing rule assumes that you do not wish to use a dialling prefix. If
you want to use a prefix to dial the remote extensions and to use the remote routing rules,
you may place a prefix e.g. 9|6XXX and 9|XX. for system 1 and system 2 respectively
instead of just 6XXX and XX.

While this method will provide some rudimentary security (though pretty
weak), as it requires an extension to be created for the peer Asterisk box, it will
not pass the calling party extension number to the remote Asterisk box.
Instead, it will pass the Trunk ID only and all calls will seem to come from the
same trunk and not individual extension – I did say that this is a simple
solution.

30.2 Method 2 - In a Peer/User Arrangement

Another method that I use is described below. This method treats both the Asterisk box
as internal to each other as peer and user. I am using IAX2 for this purpose, however I
believe, you may be able to do this with SIP as well if you are trying to connect the older
Asterisk with the newer incarnations (I have not proved it yet). This method does not
require registration either and does not require you to create extensions for the peers. In
many ways, this is simpler to set up.

Unlike the first method, this second method will pass the Caller ID to the receiving party.
The receiving party will actually get the callers’ extension number/ID instead of the
extension number of the peer Asterisk box.

Rather than being verbose, I will illustrate this method using tables as follows:

System 1 System 2
def.com.au xyz.com.au
IAX2 Trunk
Outgoing Dial Rules: XX. XX.
Trunk Name InterOffice InterOffice
host=xyz.com.au (or System 2 IP) host=def.com.au (or System 1 IP)
Peer Details Qualify=yes Qualify=yes
type=peer type=peer
User Context InterOffice-In InterOffice-In
context=from-internal context=from-internal
User Details host=xyz.com.au (or IP) host=def.com.au (or IP)
type=user type=user

Office extensions) others go via Main Office)
9|XX. (To call external number
via Main Office)
Trunk Sequence IAX2/InterOffice IAX2/InterOffice

30.3 Method 3 – Friend/Friend Arrangement

(By far the simplest method)

This method is by far the simplest method where the boxes are treated as friend to each
other. Like Method 2, registration is not required and this method will also pass the Caller
ID to the receiving party.

System 1 System 2
def.com.au xyz.com.au
IAX2 Trunk
Outgoing Dial Rules: XX. XX.
Trunk Name InterOffice InterOffice
host=xyz.com.au (or System 2 IP) host=def.com.au (or System 1 IP)
Peer Details Qualify=yes Qualify=yes
type=friend type=friend

Office extensions) others go via Main Office)
9|XX. (To call external number
via Main Office)
Trunk Sequence IAX2/InterOffice IAX2/InterOffice

All the above examples assume that both Asterisk boxes have Public Fix IP address. If
you have Dynamic IP addresses, you will need to register both the boxes with DynDns to
obtain a valid DNS ID. If you are a part of a Corporate LAN, than you will have no need
to worry about DynDns and what not.

Warning: You must provide for security, as this is pretty wide open.

Like all installation, you must provide for security. As different installation resorts to
different types of security arrangement, I will leave that to the individual implementer to
deal with the security issues.

TRIXBOX-2 Without Tears Page 134 of 224

 30.4 Thinking of more than 2 boxes?
Just as a matter of interest, you can connect several boxes using this method. While I
have connected 3 boxes successfully, I believe, the same principle can be applied to
more boxes.

In my implementation I have box A, B and C (System 1, 2 and 3) in a star

configuration. Box A is the master box. All the other boxes use box A as the
main exchange.

A peers with B and C - B peers with A - And C peers with A.

Except for local traffic, all external and inter-office (inter-branch) traffic goes
via Box A. – with the appropriate dial plan of course.

Both the above methods, while useable for a basic configuration, will not provide you with
a complete solution. To provide a complete solution is beyond the scope of this
document.

The following link will provide further reference for connecting two Asterisk boxes together
http://www.voip-info.org/wiki/view/Asterisk+-+dual+servers

If you require a complete solution tailored to your exact requirement, my advise to you is
to hire a VOIP consultant.

30.5 Redirect Incoming in Box A to Box B

There will be times when you will want to redirect certain calls made to one Trixbox box to
another Trixbox box in another location. This can happen in a scenario where you are
moving your mail office from your existing location to another location (or moving your
sales office to another location away from your main office).

Personally I really wouldn’t do this as it is simpler to get a redirection to the new number from
the exchange.

In this example, lets say that all calls coming to your head office Trixbox PABX made on
phone number 12345678 need to be sent to your Trixbox PABX in a different location.

Let us call your Head Office PABX Box-A and your remote PABX Box-B and calls coming
in to Box-A to be sent to Box-B.

There are a number of ways that this can be achieved but most involved editing conf files
and adding extra codes in the conf files. Unless you are quite comfortable with doing this,
it can be quite daunting to the uninitiated.

The example I am illustrating here does not involve editing any conf file. All can be done
through freePBX. It is a little long winded but you don’t have to touch any of the conf files.

Step 1 – (Do this in Box-A)

i. Create an IAX Trunk

You will only need the following in the Outgoing Setting and leave everything else
blank. Let us call this trunk TransferTrunk.

host=BoxB.com.au (your qualified DNS or the IP address)

type=peer

TRIXBOX-2 Without Tears Page 135 of 224

 username=6000 (this number will be used later)

ii. Create and Outbound Route

After you have created the trunk, you will need to create an outbound route. Let us
call this outbound route TransferRoute.

In the dial pattern, you will only require one entry:

6000

The trunk sequent will be TransferTrunk only.

iii. Create a new extension

Next create a new extension e.g. 500. You will be using this extension to
unconditionally forward all calls made to this extension, to extension 6000 in BoxB
which we will create later.

To unconditionally forward calls made to this extension to extension 6000, you need
to connect to extension 500 using a softphone and dial *726000. Any calls to this
extension will be unconditionally forwarded to extension 9000.

iv. Create and inbound route

DID number is 12345678. This is your phone number of calls come in to Box-A from,
assuming that all calls that come on this number are to be transferred to Box-B.

Set Destination to Core 500.

That’s all need to be done in Box-A

Step 2 – (Do this in Box B)

i. Create a Trunk
Trunk name: TransferTrunk. Leave the peer details blank.

User context: Transfer-In

You will only need the following in the Incoming Setting and leave everything else
blank.

context=from-trunk

ii. Create a new IAX extension

Create a new IAX extension 6000 (this is the username defined in the outgoing
setting in Step 1 above). Display name: CallTransfers.

Edit this extension context to read from-trunk (instead of from-internal).

iii. Direct all calls to IVR

Ensure that incoming route direct calls to the appropriate extension. In my case, all
calls go to IVR.

That is all we need to do and from now on, calls that come in to Box-A on your phone
number 12345678 will be directed to extension 500 of Box-A. However, since all calls to
extension 500 has been unconditionally redirected to extension 6000, asterisk will forward
the call to extension 6000 which your outbound route will pick up and send to Box-B.

When it gets to Box-B, it will be answered by the IVR in Box-B.

31 CUSTOMISED VOICE
The default pre-recorded voice prompts and announcements in TRIXBOX are suitable for
almost every situation, however there will be times when customised voice prompts or
announcements will be required, e.g. to mix English and other language on a single
announcement.

Although there are separate voice sets that can be used, sometimes we only require a
few prompts and not the entire voice set.

31.1 Customising Voice Prompts

To satisfy this requirement, custom voice prompts can be recorded individually by using
the System Recording facility of freePBX as covered in the chapter referring to System
Recording earlier in this document.

However, if you want to manually cut the script, you can do the following (personally I
wouldn’t bother – why re-invent the wheel?). Under the [from-internal-custom] context
of extensions_custom.conf, add the following codes.

[from-internal-custom]

; For custom recording

exten => 5678,1,Wait(2)

exten => 5678,2,Record(/tmp/my-recording:gsm)
exten => 5678,3,Hangup

; for playback of custom recording

exten => 5679,1,Playback(/tmp/my-recording)

exten => 5679,2,Hangup

To start recording, use one of the phone extension and dial 5678. At the beep, start
recording the voice prompt.

The voice prompt will be saved as my-recording.gsm (gsm format) in the /tmp directory.

When completed, hang up and dial 5679. The voice prompt will be played back.

If you are not satisfied, repeat the above process.

Once you are satisfied, rename the file to something related and recognisable e.g.
my_office_business_hours.gsm. The file should then be moved to the
/var/lib/asterisk/sound directory.

The file can be played through your custom applications or prompts using the Playback
or Background function of Asterisk.

A good information on Asterisk sound files and how to create them can be found here
http://voip-info.org/wiki/view/Asterisk+sound+files

TRIXBOX-2 Without Tears Page 137 of 224

 31.2 Installing Other Languages
If you wish to use a different language other that the default American English that comes
with Asterisk, there are a couple of ways that you can do but as this guide is for
beginners, I will go the easiest method.

Create a subdirectory for the particular language (eg: ‘au’ for Australian English, ‘fr’ for
French, ‘it’ for Italian etc.) in the /var/library/asterisk/sounds directory, e.g.
/var/library/asterisk/sounds/au and send all your prompts sound files there. Also create
the language directories in the digits, letters etc directories, and send the entire prompt
files there.

Add the following line in the iax.conf and sip.conf configuration file under [general]. In
zapata.conf configuration file the line should be added under [channels].

language=au ; (or fr, it or whichever language is installed)

You may use the Edit Configuration facility of TRIXBOX, otherwise you can use
nano at the command prompt of your Asterisk box (or SSH to your Asterisk box) to
edit the files that resides in the etc/asterisk directory.

31.3 Converting WAV files

For those who wish to record their own sound prompts, the following may be of some
assistance.

Trixbox will be able to play virtually any sound that it has the codec for e.g. wav(pcm),
wav49, gsm, g711, g729 etc. However, the gsm format seems to be the common format
used for the default voice prompts.

31.3.1 Converting WAV to GSM

Since the WAV format is the most common format that is being adopted when
recording with a windows based PC, and most times, the windows based WAV format
does not play well with asterisk, below is a method of converting the windows
recorded WAV format to GSM using SOX.

Your result will be better if you record your sound files in mono, 16 bit, 8000 Hz.

After recording the WAV sound files, transfer the sound files to the TEMP directory of
the Trixbox PC. In this example, let,s call one of the sound files hello.wav.

Login as root and change directory to the directory where you have transferred
the sound files to e.g. cd /tmp

At the prompt issue the following commands.

• If your sound files were recorded in mono, 16 bit, 8000 Hz

sox hello.wav hello.gsm

• If your sound files were recorded in mono but NOT 16 bit, 8000 Hz

sox hello.wav -r 8000 hello.gsm resample -ql

TRIXBOX-2 Without Tears Page 138 of 224

 • If your sound files were recorded in stereo, you will need the –cl switch.

sox hello.wav -r 8000 –cl hello.gsm resample –ql

• if your sound files were recorded in ADPCM wav files, to convert to standard
wav file;

sox hello.wav -r 8000 -c1 -s -w hello-out.wav resample -ql

Next, move the sound file to the sound directory where all your prompts are
stored and you are done.

You may also convert a number of WAV files at once using the following command.
In this example, lets assume that the files were all recorded in stereo;

for a in *.wav; do sox "$a" -r 8000 -c1 "`echo $a|sed -

e s/wav//`gsm" resample –ql

31.3.2 Converting WAV to SLN

Starting from Asterisk version 1.2.0, the .sln (SLINEAR) format seems to be the
format that is being adopted (the GSM format is still commonly being used), so don’t
worry about converting your existing prompts.

To convert wav file to sln, use the following command:

sox hello.wav -t raw -r 8000 -s -w -c1 hello.sln

Further reference for converting wav sound files can be found here at voip-info.org.

32 MOH (MUSIC ON HOLD)
Trixbox comes with a number of preinstalled music on hold selections, however you may
want to add your own music to the existing selection or remove the default selection
altogether, and only use your own selection instead.

32.1 Customising MOH

TRIXBOX supports native MP3. To change or add to your music on hold collections,
simply upload all your MP3 to TRIXBOX through the Onhold Music screen of freePBX.

You may also need to add the following, under [channels] in your zapata.conf file:

musiconhold=default

Pretty much any mp3 will work with Trixbox. Prior to that, it's better to convert it to a
standard format. When converting my MP3 music, I use FreeRip and convert the music
as per the following:

Bit Rate: 128

Mono
Constant Bit Rate (CBR)

Make sure that there is no ID3 Tagging.

I found that this conversion gives me the most satisfactory result.

To customise your music to your favourite, you may need to create a new music category
directory to hold your favourite music. Do this through the freePBX “On Hold Music” GUI
interface. I call my category favourites.

Upload your favourite music to this directory. Again, do this through the freePBX GUI.
Once finished uploading, click the “Enable Random Play” button and the red bar.

Make a little change to your musiconhold.conf file like the example below (this way you
don’t have to delete the music in your default directory).

You will now have to get used to the newer approach (it no longer uses the [classes] tag):

The musiconhold.conf files in 1.2 is now set out differently as per the example of my file
below:

musiconhold.conf
;
; Music on hold class definitions
; This is using the new 1.2 config file format, and will not work with
1.0
; based Asterisk systems
;
[default]
mode=files
;
; valid mode options:
; quietmp3 -- default
; mp3 -- loud
; mp3nb -- unbuffered
; quietmp3nb -- quiet unbuffered
; custom -- run a custom application
; files -- read files from a directory in any Asterisk supported format
;
directory=/var/lib/asterisk/mohmp3/favourite ;<- I pointed this to my favourite

TRIXBOX-2 Without Tears Page 140 of 224

 random=yes
#include musiconhold_additional.conf

The corresponding entries can be found in musiconhold_additional.conf – see below:

musiconhold_additional.conf

[acc_1]
mode=files
directory=/var/lib/asterisk/mohmp3/acc_1/
random=yes

32.2 MOH for different trunks

So you are hosting three different sections of your business on your Trixbox with three
different Phone numbers (or trunks for that matter) and would like to have different music
on hold for the different Music On Hold for each of the section.

While freePBX does not have a ready method of doing it from the GUI, we can trick the
system into doing it with a simple creative modification. Here goes.

Create 3 separate music categories (Rock, country and classical) and populate them with
MP3s or whatever that turns you on.

Create 3 custom context in extensions_custom.conf

[custom-department_1]
exten => s,1,playback(pls-wait-connect-call)
exten => s,n,SetMusicOnHold(country)
exten => s,n,Dial(SIP/2001,60,r)
exten => s,n,Macro(vm,2001); voice mail to extension if no answer
exten => s,n,Hangup

[custom-department_2]
exten => s,1,playback(pls-wait-connect-call)
exten => s,n,SetMusicOnHold(classical)
exten => s,n,Dial(SIP/2002,60,r)
exten => s,n,Macro(vm,2002); voice mail to extension if no answer
exten => s,n,Hangup

[custom-department_3]
exten => s,1,playback(pls-wait-connect-call)
exten => s,n,SetMusicOnHold(Rock)
exten => s,n,Dial(SIP/2003,60,r)
exten => s,n,Macro(vm,2003); voice mail to extension if no answer
exten => s,n,Hangup

Assuming 2001,2002 and 2003 being the extensions of the various departments,

Incoming route for Trunk1 send to

Custom App custom-department_1,s,1

Incoming route forTrunk2 send to

Custom App custom-department_2,s,1

Incoming route forTrunk3 send to

Custom App custom-department_3,s,1

 32.3 Streaming Music on Hold
Streaming music on hold is not directly supported using the GUI of TRIXBOX or freePBX,
however if you are prepared to do a little editing of the musiconhold.conf file, you will be
able to get it working somehow.

Below is what I have to do to get Streaming On Hold for my system. I realised that it is
not the best method, but for the sole purpose of getting Music on Hold, it got me working.

From command line, find out if you have mpg123 installed using the following command.

mpg123 –v

You will find out if you have mpg123 installed or not and its version number. The version
that we want is mpg123-0.59r.

Since I do not have mpg123 installed, first I have to download and install mpg123 - it is
not included in Trixbox implementation of Asterisk. To get mpg123 I have to log on as
root and at the command prompt I did the following:

cd /usr/bin
wget http://www.mpg123.de/mpg123/mpg123-0.59r.tar.gz
tar –zxvf mpg123-0.59r.tar.gz
cd mpg123-0.59r
make linux
make install
ln -s /usr/local/bin/mpg123 /usr/bin/mpg123

I have to make a directory for the streaming music. You can do this though the freePBX
GUI or manually. In this example, I have shown the manual method.

su asterisk
cd /var/lib/asterisk/mohmp3/
mkdir stream

Next I need to create a zero length dummy MP3 file for this purpose in the
/var/lib/asterisk/mohmp3/stream directory (this can be done manually).

cd stream
touch stream.mp3
exit

Now I have to do some editing of my musiconhold.conf file.

Open the musiconhold.conf file using the Config edit option on your Trixbox and add the
following lines on top of the file;

[classes]
default => quietmp3:/var/lib/asterisk/mohmp3/stream,http://128.177.3.80:4064/

and leave everything else out (or commented out) like my example below.

The http://128.177.3.80:4064/ (SKY.FM – Country) is where I get my streaming music

from.

This is what my musiconhold.conf looks like.

[classes]
;default => quietmp3:/var/lib/asterisk/mohmp3/stream,http://202.6.74.107:8060/triplej.mp3
default => quietmp3:/var/lib/asterisk/mohmp3/stream,http://128.177.3.80:4064/

TRIXBOX-2 Without Tears Page 142 of 224

 ;
;#include musiconhold_custom.conf
;#include musiconhold_additional.conf

The lines in BOLD are the lines that was added to the musiconhold.conf file.

After having done that you may reboot or restart asterisk.

amportal restart

The above is not necessarily being the best way to approach it but that is the only way
that I know of for now. I would like to hear fron those with alternative ways.

The following are addresses where you may find some streaming music for your MOH.

33 BACKUP AND RESTORE
Backup and Restore are two of the mandatory functions of any application. FreePBX is
no exception. With this in mind, the developer of freePBX has incorporated this facility in
freePBX under the Tools section.

Provision for flexibilities was built in this tool. You can schedule your backup, Daily,
Weekly, Monthly, Ad-Hoc and even hourly if you wish to. Therefore there is no excuse for
not making a regular backup.

33.1 Schedule a Backup

To schedule a backup, from freePBX choose Tools -> Backup & Restore

You will then be presented with the following screen:

Next select Add Backup Schedule

TRIXBOX-2 Without Tears Page 144 of 224

 The screen that follows is where you define your backup requirement.

I have chosen to schedule a Weekly (on Sundayst) backup as per the illustration above:

• In the Schedule Name, I have given it a name Weekly (to signify that it is a
weekly job)
• I have also selected all the items to be backed up – VoiceMail, System
Recordings, System Configurations and CDR only.
• Next from the Run Backup drop down choice, I have chosen Weekly (on
Sundays)

Once I have done these, I click on Submit Changes.

Naturally you can schedule numerous backups. It is up to you to decide. If you are
wondering where it is being stored, it is here /var/lib/asterisk/backups. The backup files
are identified by the backup names.

If this is the first time you schedule a backup, it is advisable to do the backup right
away by selecting Now from the Run Backup drop down selection box. After this is
done, you may start scheduling your regular backup by selecting the appropriate
option presented to you.
.

TRIXBOX-2 Without Tears Page 145 of 224

 33.2 To Restore a Backup
Backup itself is not useful if it cannot be restored. The freePBX developer has thought of
this too.

This is a very simple procedure. All you need to do is click on the Restore option and the
rest are all a matter of choosing what it is that you want to restore.

34 SUGARCRM
SugarCRM is a contact management software that comes bundled with Trixbox.

To set up SugarCRM, first, you need to open the SugarCRM application

http://<your.Trixboxip.address>/crm using the default username of Admin and the
password of password.

For security reason you should change the Admin password. To do this, click on 'My
Account' in the upper right-hand corner, then click on the 'Change Password' button
underneath 'Users: Administrator (Admin) in the center-left of the screen.

Change it to a new password and confirm your new password and click 'Save.'

Now it's time to set up your contacts. I will start off setting up a couple of my internal
extensions.

Click on 'My Account' again and then click the 'Edit' button.
Change 'Asterisk Phone Extension' to your Asterisk extension. My extension is 2001.

While you are at it, change your time zone and date format as well.

Click 'Save' to save that information.

Let's add another one.

Click on the contacts tab and then select 'Create Contact' from the left hand Shortcuts
menu.

Add another extension, in my case I chose my daughter’s extension 2002:

Firstname: Norsurya
Last name: Sharif
Home: 2002

Click 'Save' to save that information.

Add another and another if you want to, using the method above.

At this point, you may find that you are unable to make a phone call through SugarCRM.
This is due to a little bug in the popup_picker.php (this bug may have been fixed by the
time you read this, but at the time of writing, this bug exists).

To fix this bug, you need to edit popup_picker.php by doing the following:

From your Linux CLI, log in as root.

cd /var/www/html/crm/modules/Contacts

nano Popup_picker.php

Browse down to line 121 and change it from:

$number = preg_replace ( "/[^\d\*]/", "", $number );

To

$number = preg_replace ( "/[^\d\*]/", "", $display_number );

TRIXBOX-2 Without Tears Page 147 of 224

 You should now be able to dial from SugarCRM to your other internal extensions and to
the outside world.

You can add multiple users who will each have their own settings/contacts etc.

35 USB PHONE SUPPORT
Most USB Phones are pre-configured for use with Skype and as a result some USB
Phone users are experiencing difficulties using the USB phones dial pads to dial out using
providers other than Skype especially when using SIP. Special driver are usually
required.

The following are links, which may interest USB phone users, where appropriate drivers
may be found. Users may have to try different drivers to find a suitable one.

36 CODEC (CODER DECODER)
When making a call over the net, the software (soft-phone) or hardware needs to use a
codec so as to send/receive information in a certain format and convert it to what you
hear. What this means to you and me is that codecs compress data, allow you to transmit
the compressed data which is then uncompressed at the receiving end. If you compress
something with G729 and you don't have that installed, then you wont be able to
decompress it and vice versa.

g729 does not come preinstalled with Asterisk – you will need to purchase it.

Different codecs have different compression ratios resulting in different bandwidth

requirements. Generally the higher the compression the more CPU power required to
compress, and sometimes decompress.

In most cases this means:

• Higher compression = More CPU power = Lower Bandwidth
• Lower compression = Less CPU power = More Bandwidth

So the more bandwidth you have, the less need for a higher compression ratio and the
less powerful the CPU that will be needed.

Most VoIP providers/hardware/licensed software will support G711 and G729 (However
be sure to check this before purchasing hardware, or signing up with a VoIP provider!),
with G711 requiring almost 3 times as much bandwidth, and providing excellent quality
and the G729 providing quality similar to a good mobile call but using less bandwidth.

Below are the approximate bandwidth requirements for Several Common VoIP
Compression Algorithms using SIP. They vary slightly depending on the protocol used.

Codec Bit Rate Nominal Ethernet Approx. MBytes

Codec
(Kbps) Bandwidth (Kbps) usage per hour
G.711 64 87.2 39.24
G.729 8 31.2 14.04
G.723.1 6.4 21.9 9.86
GSM 13.2 28.7 approx 12.92 approx
iLBC 15.2 30.83 approx 13.87 approx
G.723.1 5.3 20.8 9.36
G.726 32 55.2 24.84
G.726 24 47.2 21.24
G.728 16 31.5 14.18

Codecs used by TRIXBOX reside in the /usr/lib/asterisk/modules directory.

The following links will give you some indications of the bandwidth usage of the various
codecs that you may be using or contemplating on using.

 36.1 Installing G729 and G723 CODECs
If you have the licence for the g729 codec and found that the digium version of g729
is a little problematic and would like to try the free version, following is the method of
installing it as described by David Klaverstyn – thanks David.

DISCLAIMER:
You might have to pay royalty fees to the G.729/723 patent holders for using their
algorithm.

Before downloading the codec module you need to verify what your processor type is,
as to get a compatible compiled codec.

From the Linux command type in:

# cat /proc/cpuinfo

Look specifically at the model name and the flags. The following is an example of the
process that I am using.

Process: 0
vendor_id: GenuineIntel
cpu family: 6
model: 8
model name: Pentium III (Coppermine)
stepping: 3
cpu MHz: 648.110
cache size: 256 KB
fdiv_bug: no
hlt_bug: no
f00f_bug: no
coma_bug: no
fpu: yes
fpu_exception: yes
cpuid level: 2
wp: yes
flags: fpu vme de pse tsc msr pae mce cx8 mtrr pge mca
cmov pat pse36 mmx fxsr sse
bogomips: 1297.41

From this information we can see that it is a Pentium III processor and it is using sse.
This is the 2 bits of required information that we need. If you don’t see sse in your
flag then the file you need must contain the words no-sse.

Now go to http://kvin.lv/pub/Linux/Asterisk/ and select wither Asterisk version 1.2 or 1.4

depending on the version you are using.

The files are named as codec_g72x-???-pentiumx.so

So from the information above to obtain the G729 codec we need to get the file
codec_g729-gcc-pentium3.so and for the G723 codec we need to get the file g723-
gcc-pentium3.so

The gcc represents the way the module was compiled. This is your most likely
choice. To view the different type of compiled version look at this file
http://kvin.lv/pub/Linux/Asterisk/README

Now that we know what file we need you can now download the appropriate file.

Change folders to /usr/lib/asterisk/modules

TRIXBOX-2 Without Tears Page 151 of 224

 # cd /usr/lib/asterisk/modules

Download the required file(s)

For the G729 codec

For Pentium III

# wget http://kvin.lv/pub/Linux/Asterisk/built-for-asterisk-
1.2/codec_g729-gcc-pentium3.so

For Pentium IV

# wget http://kvin.lv/pub/Linux/Asterisk/built-for-asterisk-
1.2/codec_g729-gcc-pentium4.so

For the G723 codec

For Pentium III

# wget http://kvin.lv/pub/Linux/Asterisk/built-for-asterisk-
1.2/codec_g723-gcc-pentium3.so

For Pentium IV

# http://kvin.lv/pub/Linux/Asterisk/built-for-asterisk-
1.2/codec_g723-icc-pentium4.so

Restart asterisk and you are done.

If Asterisk does not start then you may need to try icc files instead of gcc.

37 PSTN TRUNK – SPECIAL HANDLING
37.1 Dial 0 for Outside Line
There will be times when a user would like to get an outside line something similar to a
PABX by simply dialling a number e.g. 0 or 9.

I got around it by creating an entry in extensions_custom.conf.

In my case I use 0 as the prefix to get an outside line.

I have also pre-recorded a voice prompt to instruct the caller what to do after the second
dial tone.

37.1.1 Using Zaptel Card Method

;##############################################
; To get outside line through ZAP - Ben 22-12-2005
; after dialling 0 will get a second dial tone.
; Then dial the number required.
; No need to press the send button after the second number dialled
;##############################################

exten => 0,1,Playback(start-dial-after-dialtone)

exten => 0,2,Dial(ZAP/1/{EXTEN})
exten => 0,3,Hangup

The example above is based on systems that have Zaptel card (e.g. TDM400 or
X100P etc.) installed. Note:* If you're using a PRI line, you need to enable 'overlapdial'
in /etc/asterisk/zapata.conf for this to work.

37.1.2 Using SPA3K Method

Using SPA3K will be a little tricky. I am describing how I got around it (assuming that
you have set up the SPA3K as described in this document), however there maybe
other method.

1. In the SPA Line 1 Tab, I have included the following entry in the dialplan:

<0:#><:@gw0>)

2. The following is what my dialplan looks like in SPA3K

(**|*xx|xx.|<0:#><:@gw0>)

3. In the PSTN Line Tab, I have the following:

• VOIP-PSTN Gateway Enabled: Yes

• VOIP Caller Auth Method: None
• VOIP Caller Default DP: None

In made the following entry in my Asterisk entensions_custom.conf

;##############################################
; To get outside line through SPA3K - Ben 25-12-2005
; after dialling 0 will get a second dial tone. Then dial the
; number required. No need to press the send button again
;##############################################

TRIXBOX-2 Without Tears Page 153 of 224

 exten => 0,1,Playback(start-dial-after-dialtone)
exten => 0,2,Dial(SIP/Telstra/{EXTEN}) ; Telstra being the name of the SPA3K trunk.
exten => 0,3,Hangup

Every time when I dial ‘0’, the SPA3K will send it to Gateway 0, which is the PSTN
line and present me with a second dial tone.

37.2 Giving Priority to Emergency Numbers (E.g. 000)

Emergencies, by definition should be given right of way. This applies to the right of using
the telephone for emergency purposes above other uses.

Imagine what will happen if you want to use the PSTN line to call emergency 000 (in
Australia) and someone else was hogging the line. The sensible way is for Asterisk to
disconnect the line and allow you to make the emergency call instead.

The following method will provide you with the facility, however you need to do some
editing to the extensions_custom.conf file in /etc/asterisk.

In my case I have pre-recorded a voice prompt called ‘calling-emergency’ which says,

“You are trying to call emergency assistance. If you have dial this in error, please hang-
up”

;###################################################
; Give priority to emergency number by disconnecting existing user
; if using the PSTN line first, otherwise simply call the emergency number.
;###################################################
exten => 000,1,Background(calling-emergency) ; voice warning
exten => 000,2,Wait(1) ; give caller a chance to hang up
exten => 000,3,Dial(Zap/1/000,,j) ; If ZAP 1 is busy, jump to n+101
exten => 000,4,Hangup() ; hang up after the call
exten => 000,104,Softhangup(Zap/1-1) ; hang up the line if being used
exten => 000,105,Goto(3) ; make call after disconnecting the other user

38 PORT FORWARDING AND QOS – ROUTERS
38.1 Port Forwarding
While most domestic routers using UPnP do not require port forwarding, some routers do.
Even if your router does not require port forwarding for TRIXBOX to work, do yourself a
favour and forward a few of the relevant ports to your Asterisk IP address anyway – it
doesn’t hurt.

IAX Port: 4569 (UDP)

Sip ports: 5004 - 5082 (UDP and TCP), more if you want to.
RTP ports: 10000 – 10500 (UDP) – this should be enough.

I am using the LinkSys WRT54G wireless router. In the example below, I have forwarded
all the ports mentioned above to my asterisk box IP, which is 192.168.1.101

These should be enough for starters.

38.2 QOS – Routers

Some routers have QOS facility while some routers haven’t. It is highly recommended
that you enable this function if your router supports it.

There have been a number of discussions on the effectiveness of QOS on broadband

utilising the public Internet circuit. It is beyond this guide to document the effectiveness or
otherwise of enabling QOS on your router. For a start, there are just too many routers
there for me to give any meaningful examples.

I use the Linksys™ WRT54G®. Taking the easy way out, I simply restrict the PCs (see
below) that more often than not will be used as a P2P client or chatting on the MSN chat
channels.

I restrict the PCs according to their MAC addresses.

TRIXBOX-2 Without Tears Page 155 of 224

 In the application priority section (see below), I have defined the various ports that I want
priority to be accorded the highest priority. In this case I have defined the port ranges
related to my VOIP requirement.

My recommendation is, if your router has the function, use it. At the very least, it will
prioritise traffic within your own LAN especially when you have sons and daughters (for
that matter you too can be the culprit) who are always on the P2P, leeching files and
music.

This may not be the best solution. If anyone has a better solution for the Linksys
WRT54G, please let me know.

39 UPGRADING YOUR SYSTEM
Mostly everyone would like to have the latest and the greatest and if you are like most,
chances are that you would certainly want to update your TRIXBOX and/or freePBX as
soon as there is a new update.

If you are currently using Trixbox version 1.x and wish to upgrade to v2.x, the following
instruction may get you there. It’s best to stop asterisk. Through SSH or the command
prompt: type:

amportal stop (Remember to always stop asterisk first before doing this)
service zaptel stop (it helps to stop the zaptel service as well)

39.1 Upgrading Trixbox

To upgrade Trixbox, its best to use the update script. At the command prompt, type the
following;

Trixbox-update.sh

You will get a prompt: ‘Can I put the new script in /usr/local/sbin (y/n) ?

Type ‘y’ for yes. Then you will get the following:

Now issue the following command:

Trixbox-update.sh update

This process will take quite a few minutes while it downloads all the necessary updates
and proceeded to install them. Make yourself a cup of coffee and wait.

You may get the following warning message.

TRIXBOX-2 Without Tears Page 157 of 224

 Just ignore the warning and let the process continue.

At the end of it, you will be asked to reboot.

reboot.

TRIXBOX-2 Without Tears Page 158 of 224

 39.2 Upgrading freePBX
There are 2 ways to upgrade freePBX as explained at the aussievoip website here
http://www.aussievoip.com/wiki/freePBX

Either one will be fine but I would like to suggest that you take the all-in-one version with
modules and be done with it. Afterall, this is the method recommended if one is on a
limited-bandwidth connection, or the FreePBX machine doesn't have easy Internet
access.

To conduct this upgrade, you will need to log on to the Trixbox PC as root.

At the command prompt, do the following;

cd /usr/src/
wget http://mirror.freepbx.org/freepbx-2.2.1-withmodules.tar.gz
tar zxvf freepbx-2.2.1-withmodules.tar.gz
cd freepbx-2.2.1
./install_amp

Once this is done, freePBX is now upgraded to version 2.2.1 and you can start managing
and/or upgrading the freePBX modules.

40 TOOLS
The following are tools that I use regularly to maintain my Asterisk systems.

40.1 Webmin
Webmin is an invaluable web based tool for managing a Linux box. Webmin make it easy
to configure application like SMTP mail, editing files etc.

Those who want to use Web Admin to maintain the Asterisk System may download
Webmin from here or from CLI, do the following:

wget superb-east.dl.sourceforge.net/sourceforge/webadmin/webmin -1.300-1.noarch.rpm

Install it with the following command through CLI:

rpm -Uvh webmin-1.300-1.noarch.rpm

Or be totally lazy like me and do the whole lot in a one liner;

rpm –Uvh http://superb-east.dl.sourceforge.net/sourceforge /webadmin /webmin-1.300-1.noarch.rpm

I have found the above method is straightforward and simple. However there are some
users who found that following an alternative method is simpler. If that is the case, the
alternative installation method can be found here:

http://www.terrasoftsolutions.com/support/solutions/ydl_general/webmin.shtml

You may connect to Webmin remotely through your browser using the following address
http://<YourAsterisk_IPAddress>:10000. E.g.

192.168.0.101:10000

If you would like to avoid clashing the port with your RTP port which is 10000 – 20000,
you may edit the file /etc/webmin/miniserv.conf and change the port value to something
else, such as 9000.

Locate the entry where it says:

Port=10000

And change this to;

Port=9000

TRIXBOX-2 Without Tears Page 160 of 224

 You can use http://192.168.0.101:9000 to connect to Webmin instead.

The alternative is to edit the /etc/asterisk/rtp.conf file like the example below and you
can keep http://192.168.0.101:10000

This will break PA1688 based phones. It's better to change your webmin.conf file

[general]
;
; RTP start and RTP end configure start and end addresses
;
rtpstart=10000 < - - change this to 10002(totally unnecessary.. ☺)
rtpend=20000

40.1.1 To update WebMin

Anytime you want to update Webmin, simply do the following.

Log on to your Asterisk box (SSH or at the console).

At the command prompt, issue the following command:

yum –y install webmin

40.2 Putty
PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along
with an xterm terminal emulator.

It is written and maintained primarily by Simon Tatham and can be downloaded from the
following link.http://www.putty.nl/download.html

 40.3 WinSCP
WinSCP is an open source freeware SFTP client for Windows using SSH. Legacy SCP
protocol is also supported. Its main function is safe copying of files between a local and a
remote computer.

It can be downloaded from the following link.

41 USE ACCESS TO CONNECT TO DATABASE
A quick and dirty way to access the Trixbox database is through MSACCESS. This will
enable you to work on the data kept in the MySQL database which Trixbox uses. You
may want to extract CDR data for reporting etc. Imagination is the restricting factor.

To do this first you must download the MySQL ODBC driver for Windows here:
http://www.mysql.org/downloads/connector/odbc/3.51.html save it somewhere in your
Windows local hard drive but do not install it yet.

41.1 Setting up a new MySQL user

Log into the TrixBox web interface, and navigate to the phpMyAdmin screen.

When selected, you will be presented the following screen.

Select and Click "Privileges" (see arrow in the illustration above) and a new screen will
pop up – see below.

TRIXBOX-2 Without Tears Page 163 of 224

 Select and Click "Add a new user" (see illustration above) and you will presented with the
following screen but all the fields will be blank. The arrows indicate all the fields that I
have filled.

TRIXBOX-2 Without Tears Page 164 of 224

 In the blank fields enter the following:

User name: enter a User name (e.g. reportis)

Password: enter a password of your choice (e.g. passw0rd)

Since the database lives in the same host, leane the Host field blank.

Under the Data section of "Global Privileges" – see arrow, check all the options. Since we
don’t really want the user to start playing oround with the structure and other aspects of
the database, leave the Structure and Administrations unticked.

Once done, click "Go" in the lower right corner of the screen to save the new user after
which you can get out of PHPAdmin.

41.2 Configure MySQL ODBC for Windows

Install the ODBC Driver that was downloaded.

Once installed, on the Windows PC, click Start -> Control Panel -> Performance &
Maintenance -> Administrative Tools -> Data Sources (ODBC)

The following screen will appear.

TRIXBOX-2 Without Tears Page 166 of 224

 Description: Call Detail Reporting
Server: 192.168.1.100 (your server IP address)
User: reports (the username you created in phpMyAdmin previously)
Password: passw0rd (the password that we entered in phpadmin earlier)
Database: asteriskcdrdb

Once this is done, click "Test" to ensure that the connection is working

Click "Ok" to save and finish and “OK” again to close the ODBC dialog box.

41.3 Connecting using MSACCESS

To connect to the CDR database using MSACCESS, you must first create a blank
database. Once the blank database has been created, the CDR table from MySQL can
then be linked to the MSACCESS database that you have created. Once doce, you can
start working on the data. Those familiar with Access can start creating a special
application for their use.

Create an empty ACCESS database. Call it reporting or whatever you like.

Select Tables as illustrated by the arrow above.

Select “Get External Data” and choose “Link Tables…” and click.

On the explorer’s screen that follows, click the drop down on the “Files of type” and select
“ODBC Database()” – see illustration below.

43 TROUBLE SHOOTING
With any installation, you will find some unexpected problems. Some are inherent issues
due to bugs or undocumented features, while others are unintentional mistakes.

We will endeavour to list troubleshooting tips as we experience them (or those suggested
by other users). These will be added progressively as we encounter them.

43.1 Debug Messages and Log Files are your friends

Whenever problem strikes, there is always a reason for it. To assist you in locating the
problem, generally there are 2 places that you can have a look at – the Asterisk Log
Files, under TOOLS (which will give you the last 2000 entried in the log).

The other is to monitor the activities of your Trixbox using the following command at the
command line (which will give you the Asterisk CLI).

Asterisk –rvvvv (the “v” depends on the level of verbosity you need)

Studying the activities will give you an indication of what has gone wrong.

TRIXBOX-2 Without Tears Page 172 of 224

 43.2 Unable to log on to Packages?
From time to time, you may be having problem logging on to “Packages” to
install/uninstall or update Trixbox modules. This has happened to me a number of time
which made me post in the Trixbox forum thinking that I may have done something
wrong.

This difficulty is due to the delay in connecting to the site (depending on how busy the site
is at the time) and you get connection time out. Trying again later may solve this problem
or you may use a hammer and fix it by changing an entry in the etc/php.ini file.

Change the max_execution_time from 30 to 60 may solve this problem. All it does is to
wait 60 seconds before reporting a time out.

43.3 Asterisk Feature Codes not working

If you are using ATAs such as the Sipura SPA3K, Linksys PAP2 etc., you will need to
delete all the Vertical Service Feature codes in the ATA, otherwise the Asterisk feature
codes such as *77, *99 etc may not work. This is caused by the ATA intercepting the
codes thinking that it is its own feature codes.

This also applies to all other ATAs, FXS devices such as the various routers with built-in
FXS ports and IP Phones that has their own feature codes built-in. Unless these feature
codes are disabled, they are likely to clash with Asterisk's feature codes and as such
Asterisk feature codes will not give you the desired results.

43.4 Asterisk Drops Calls after a few seconds

If Asterisk rings an extension but drops the calls too soon before it was answered,
chances are, you may have set the ‘Number of seconds to ring phones before sending callers
to voicemail:’ too short. This setting can be found in the General Setting under
Voicemail.

43.5 Pennytel Asterisk Problem

Pennytel, for some reason rejects user agent if it is Asterisk. To work around this, you
are required to introduce the following line in your sip.conf under [general]

useragent = My PABX ; required if you are with Pennytel

The user agent can be any string as long as it is not Asterisk.

43.6 Unable to receive Incoming Calls

If you are unable to receive incoming calls, chances are that you may have missed setting
up the incoming call handling as suggested in the previous sections of this guide.

A quick fix for TRIXBOX is to create an Inbound Route with the DID and CID field left
blank. At least this will let incoming calls through while you try to solve the problem.

Please refer to the following section on Calls Handling in this guide:

43.7 Sipura SPA3000 – Not hanging up after PSTN Calls

For months I have to wrestle with the problem of SPA3K not hanging up after a PSTN
call. Although the caller has hung up, SPA3K will hold the line off hook until I manually
power cycle SPA3K.

TRIXBOX-2 Without Tears Page 173 of 224

 The following settings may overcome the problem:
.
PSTN Line Tab

PSTN Disconnect Detection

Detect CPC: yes

Detect Polarity Reversal: yes
Detect PSTN Long Silence: yes
Detect VoIP Long Silence: yes
PSTN Long Silence Duration: 180
VoIP Long Silence Duration: 180
PSTN Silence Threshold: medium
Min CPC Duration: 0.2
Detect Disconnect Tone: no
Disconnect Tone: Leave blank

I deleted my original Disconnect Tone setting of: 425@-30,425@-

30;1(.375/.375/1+2) which seems to work well for Telstra, and replaced it with
425@-30,425@-30;1(.390/.390/1+2) which works better with Optus.

Only one catch with this: if you put somebody on hold for longer than the above settings,
if they don't make any noise, it will hang up.

B.1.4 iPrimus

Primus is a strange animal. To get it to work with Trixbox requires me to do a bit of

detective work. With my partner in crime, Colin, we set out to play detective because
we need to obtain the correct credential to get Trixbox to register and to be able to
make and receive calls through Trixbox. Primus Telecom has refused to assist.

To get the necessary credentials, we cheated a little as the method was published in
the whirlpool forum http://forums.whirlpool.net.au/forum-replies.cfm?t=604015

First of all, using a browser, we need to enter the following address:

C.1 Voice for Asterisk Messages

Brian, a Whirlpool Enthusiast, posted the following tip in the Whirlpool forum. Brian has
asked me to include his discovery in this guide.

The following is an extract of Brian’s exploits – verbatim ☺

<Quote>

I have just been setting up the Digital Receptionist and I wanted to use a professional
voice for messages. I thought I might detail my exploits here for those that might be
considering the same thing.

First you need the original recording either from a real professional or a "text to voice"
utility. I went with the Realspeak demo
http://www.nuance.com/realspeak/demo/default.asp

The "British Daniel" voice was deep and professional. Check this out
http://www.cbservers.com.au/whirlpool.wav

Now the demo has a 100-character limit so you may need to do 2 or 3 files and join them
together with a program like Accoustica MP3 mixer.
http://www.acoustica.com/mp3%2Daudio%2Dmixer/

Save it as a wav file.

It was after this part that I had a lot of problems. Asterisk is very funny about sound files. I
tried using all sorts of programs to get the file to the right specs but it failed to work every
time. I eventually used "sox" an open source command line editing tool and it worked first
go (using advice from VoIP-info & digium forums) http://sox.sourceforge.net/ then at the
command line prompt use this syntax:

sox winwave.wav -r 8000 -c 1 -s -w linwave.wav

you may then upload your message to asterisk.

 C.2 Australian Voice and Language Set for Asterisk
VOIPSHOP has made available the files free to non-commercial users. Log on to
http://www.voipshop.com.au/product_info.php?products_id=72 to download

The following is extract of the instructions by VOIPSHOP on their web site. Two files are
available; one is as a replacement for the current asterisk files. The other is as an
additional Asterisk language (if you are going to use the SetLanguage option).

Replace Current Asterisk Files: ausounds.tar.gz

Quick Steps for TRIXBOX.

Log into your TRIXBOX server and at the command prompt, do the following:

wget http://files.voipshop.com.au/ausounds.tar.gz
tar cvfz backupsounds.tar.gz /var/lib/asterisk/sounds/ (for backing
up your existing files)
tar -zxvf ausounds.tar.gz -C /var/lib/asterisk/sounds/

Done. Your asterisk sound files are replaced. Make sure you back up, just in case.

Additional Asterisk Language Set: ausoundset.tar.gz

At the command prompt execute the following commands:

wget http://files.voipshop.com.au/ausoundset.tar.gz
tar -zxvf ausoundset.tar.gz -C /var/lib/asterisk/sounds/

Done. Your asterisk sound files now contain an au soundset.

Note : You can only download these files from voipshop,

Please do not re-distribute. These are free for non-commercial use only. Contact
VOIPSHOP mailto:support@voipshop.com.au for commercial license details.

C.3 More Australian Voice for Asterisk

As part of OpenVoice contribution to the Asterisk community, they are offering a free set
of Australian prompts for the Asterisk™ Open Source PBX.

The files (male voice) can be downloaded here: http://www.openvoice.com.au/free.php

Of course, don’t forget to add the following line in the iax.conf and sip.conf configuration
file under [general]. In zapata.conf configuration file the line should be added under
[channels].

language=au ; (or fr, it or whichever language is installed)

APPENDIX D (ATAS AND ROUTERS)
D.1 Alcatel SpeedTouch 510/530 ADSL Router
If you are using Telstra Alcatel SpeedTouch 510/530 ADSL Router, you will need to
unbind port 5060, otherwise you will not be able to use VOIP since Alcatel, in their
wisdom for reasons best known to themselves, have decided that we are not suppose to
use this port. So they blocked it in these types of routers.

But, as we know, there are more than just one way to skin a cat ☺ thus, the solution is to
telnet to the ADSL modem and remove this restriction.

I am assuming that you are running a Windows PC to do this.

Click on Start > Run then type:

telnet 10.0.0.138 [or replace with the correct ip address]

you will notice the following;

Trying 10.0.0.138...
Connected to speedtouch
Escape character is '^]'.
Username : root
Password :
----------
...
... welcome message blah blah blah
...

You then should unbind the SIP protocol and reboot the modem thus:

=>nat unbind application=SIP port=5060

=>config save
=>system reboot

To check whether the SIP protocol is bound in your modem use this command to show
the list of bindings (only showing SIP here):

=>nat bindlist
Application Proto Port
SIP udp 5060

If the line doesn't appear, your phone should work.

D.2 Billion 7402 VL

Some extra information that will get a Billion 7402 VL FXS to work with asterisk and have
NAT port 5060 points to the Asterisk server.

By default, if you enable the FXS ports on the Billion 7402 VL router to be sip enabled,
the router automatically forwards the port (5060) to its own IP address and an error will
occur if you try to forward that port to the Asterisk box. This is because it is intended for
the FXS ports to connect directly to an external SIP provider.

TRIXBOX-2 Without Tears Page 199 of 224

 To overcome this issue and make the FXS ports connect to the Asterisk box, complete
the following:

From a windows command prompt…

telnet 192.168.XXX.XXX (router I.P. address)

voip set interfacename iplan (this changes it from the WAN to the LAN interface

Next, power reset the router.

Now you can add the NAT to point to the asterisk server and the FXS ports will connect to
the Asterisk box.

NOTE: - Also codec G729 had to be disabled on the FXS ports for calls to work. Not sure
why.

D.3 Linksys PAP2 and Sipura SPA2000

The most common Analog Telephone Adapters (ATA) amongst Australian VOIP users
are the Linksys PAP2, Sipura 2000 and Sipura SPA3000 (the Sipura SPA3000 was
covered in the chapter relating to Interfacing Asterisk to PSTN). The Linksys PAP2 and
the Sipura SPA2000 are essentially identical units encased in different boxes and
branded differently. The examples presented here apply to both the Linksys PAP2 and
Sipura SPA2000.

Note:
The set-up described here is for use with TRIXBOX and not for connecting the unit
directly to the VOIP service provider.

I will describe the minimum changes that are required to get these ATAs to work in
conjunction with Asterisk.

As supplied, the unit comes with DHCP enabled. It is best to allocate a fix IP address to
the unit and therefore the first thing to do is to disable the DHCP and allocate a fix IP
address e.g. 192.168.1.50. You need to do the following:

1. Connect the unit to your network via the RJ45 port behind the unit.
2. Power up the unit
3. Plug in a telephone in the RJ11 port 1 behind the unit (any one will do)
4. Dial **** and listen to the instruction that you will hear from the IVR
5. Dial 101 and when prompted enter 0 followed by # (this will disable DHCP)
6. Dial 111 and when prompted enter 192*168*1*50 followed by # (assuming that
you want to allocate 192.168.1.50 as the IP address of the ATA).
7. Dial 120 and you will hear the current sub-net mask. If it is not your existing
network subnet mask you may want to change it. If it is the same as your current
network’s subnet mask, do don’t need to do anything else). If you need to
change the sub-net mask, do the following:
8. Dial 121 and at the prompt enter 255*255*255*0 (assuming that is your existing
sub-net mask)

Next, connect to the Unit using your browser by entering http://192.168.1.50 in your
browser address bar and hit enter.

TRIXBOX-2 Without Tears Page 200 of 224

 1. Select Admin Login and then select (switch to advanced view)
2. Select the System Tab
a. Under Internet Connection Type, change the Gateway address to the
address of your router.
3. Select Regional Tab
a. Under Vertical Service Activation Codes, delete all the fields.
4. Select Line 1 Tab
a. Under SIP Setting, change the SIP Port to 5060
b. Under Proxy and Registration, change the Proxy to reflect the address
of your Asterisk box.
c. Under Subscriber Information, change the Display Name to whatever
you like, change the User ID to the Asterisk Extension number that you
have allocated for this line e.g. 201. Change the Password to the
password you have allocated to the asterisk extension. Change Use
Auth ID to Yes. Change the Auth ID to the extension number you have
allocated e.g. 201, the same as the User ID.
d. Under Dial Plan, change the existing dial plan to (*x.|x.) Change Enable
IP Dialling to yes.
5. Select Line 2 Tab
a. Under SIP Setting, change the SIP Port to 5061
b. Under Proxy and Registration, change the Proxy to reflect the address
of your Asterisk box.
c. Under Subscriber Information, change the Display Name to whatever
you like, change the User ID to the Asterisk Extension number that you
have allocated for this line e.g. 202. Change the Password to the
password you have allocated to the asterisk extension. Change Use
Auth ID to Yes. Change the Auth ID to the extension number you have
allocated e.g. 202, the same as the User ID.
d. Under Dial Plan, change the existing dial plan to (**|*x.|x.) Change
Enable IP Dialling to yes.

These are the minimum changes you need to do to get the ATA working in conjunction
with Asterisk. There are other changes that you can do depending on your own
requirement. There are various discussions on this topic in the Whirlpool, Voxilla and
other forums that you can refer to.

E.2 MULTIPLE TDM400P INSTALLATION
Neilmc, a participant I the Whirlpool Forum provided the following feedback on the use of
multiple TDM400P Digium cards.

This is being discussed in this thread:

http://forums.whirlpool.net.au/forum-replies.cfm?t=483550&p=1

<quote>
There are plenty of forum posts (on WP and elsewhere) + various how-to and guides that
say don't use more than one if you want a reliable system with no audio problems.

I'm sure that on the old Digium site they had a caution not to use more than one TDM or
TE card (That's changed, they now brag about 1 box running 5 quad span TE cards).

This machine is now working in a busy environment (medical centre) nicely, sometimes
under full Zap call load. It has 5 x FXO & 5 x FXS on 3 cards. CPU is under 10% pretty
much all the time.

I asked them to be very fussy about audio quality and let me know if they have any echo,
pops, clicks, distortion etc.

So far everyone is saying that it's perfectly fine, not a bad call yet.

There is good reason behind the old advice not to do it though. Lots of people have had
grief.

Make sure you don't grab any old motherboard that is lying about (especially if it isn't PCI
2.2 compliant) Even though minimum system specs aren't high don't go for a bottom of
the range el-crapo brand motherboard. There is a list of some incompatible motherboards
on the Digium site, but no doubt there will be others that have problems.

Choose a board that has plenty of PCI slots (5 or so). Make sure that it has plenty of
control over IRQ in CMOS. Eg the ASUS P5P-800 I used could use APIC to assign IRQ
or you could manually assign an IRQ to a particular PCI slot.

Be very sure that each Digium card is not sharing an IRQ with anything else.

Disable any onboard devices you don't need inc. serial, parallel & USB ports.

It may not be a problem, but to minimise chances of problems disable Hyper threading if it
is supported on your CPU. Use 32 bit OS rather than 64 bit.

Use plenty of RAM. You don't want a PABX to be thrashing about with a swap file. I used
1GB of decent quality RAM which is definitely far more than the system needs. (It's using
about 230MB at the moment), but 1GB of RAM doesn't really cost much any more.

Check that your hard drives are running in DMA mode (or use SCSI drives). Sometimes
they default to PIO, which might cause problems if there is a sudden burst of disk activity.

Sometimes APIC can cause you grief. You might be able to tweak your kernel, but you
might get what you need by turning it off.

If you have all of the driver stuff loading properly and still have audio problems.

Use recent zaptel drivers (unless you become aware of an issue with them).

TRIXBOX-2 Without Tears Page 203 of 224

 • Make sure that the driver loads with the module option opermode=AUSTRALIA.

• Run fxotune -i 4 (usually from /usr/src/zaptel) It will create a file /etc/fxotune.conf

with settings for your cards based on tests with your lines (takes about 5 minutes
per FXO port).

• You will have to stop Asterisk before running fxotune.

• Have /usr/src/zaptel/fxotune -s run at startup to have the card set. Apparently the
values in the conf file are often zero if you have the modules in the correct
opermode. ( have one module at the office where the first value is 10 rather than
zero. I'll try fxotune again and see if it changes at all).

I just put /usr/src/zaptel/fxotune -s at the bottom of /etc/rc.d/rc.local in A@H 2.6 and it

loaded okay. You need it to run after the drivers load but before asterisk starts.

• Check /var/log/messages after boot up. Each FXO port should have loaded with
AUSTRALIA mode. If it is FCC mode then the card is set for North American
lines.

• Each FXS port should have an entry for boosting ringer.

If fxotune is loading settings okay you should see a line saying something like after all of
the other init stuff.

kernel: -- Setting echo registers:

kernel: -- Set echo registers successfully

If you have 4 FXO ports, you should see this 4 times.

 E.3 Eliminating Echo Problems in SPA-3000
Tony, another participant in the Whirlpool Forum, provided the following recommendation.

Echo in the SPA-3000 is a common problem. In reality, most of the time the SPA-3000
isn't causing the echo, it's just making it more noticeable. This is due to the fact that the
SPA-3000 passes calls from the PSTN to the LINE1 by converting it to VoIP internally
and then backs to analogue. This process does not produce any echo, however is can
add about 30ms of latency to the call. This added latency can make echo that was
previously unnoticed suddenly become annoying. A pure digital system has no echo (the
TX and RX path are 100% separated). It's the interaction of the Digital and Analogue that
cause problems.

This may help getting rid of that pesky echo on your Sipura SPA-3000 PSTN line:

1. Make sure you are running the latest firmware (3.1.7) and you have everything back to
factory defaults or at least undo all the previous tweaking.

2. Switch *off* all echo can in all your devices. There are 6 places in the sipura to switch
off echo can.
• PSTN Line -> "Echo Canc Enable",
• "Echo Canc Adaptive Enable",
• "Echo Supp Enable" and
• Line 1 -> "Echo Canc Enable",
• "Echo Canc Adaptive Enable",
• "Echo Supp Enable".

The idea is that we want to hear how bad the echo is with different configs.

3. Unplug everything from your phone line except the SPA-3000. This includes all the
extension cables even with nothing connected to them. These can cause impedance
problems that lead to echo.

4. Set the Impedance on your lines.

• PSTN -> "Port Impedance" = 220+820||120nF as a starting point.
• Regional -> FXS Port Impedance = "220+820||115nF" as a starting point.

5. In the PSTN tab set –

• "Tip/Ring Voltage Adjust: = 3.1V" and
• "Operational Loop Current Min = 16mA".

Doesn't seem to affect echo, but I believe that these are the correct numbers for
Australia.

6. Turn down the jitter buffers!

• "PSTN -> Network Jitter Level: = low",
• "PSTN -> Jitter Buffer Adjustment: = disable".

This reduces the delay across your SPA-3000.

• "LINE1 -> Network Jitter Level: = low",
• "LINE1 -> Jitter Buffer Adjustment: = up and down".

If you are using a poor quality VoIP service as well as the PSTN then you could change
the
• "LINE1 -> Network Jitter Level: = medium".

7. Set the preferred codec for the PSTN to be g711a and lock it in.
• "PSTN -> Preferred Codec = g711a",
• "PSTN -> Use Pref Codec Only = yes".

TRIXBOX-2 Without Tears Page 205 of 224

 Obviously adjust this if you’re accessing your PSTN line via VoIP from a remote network.
Set the LINE1 to allow g711a as well as whatever else your prefer.
• "LINE1 -> Use Pref Codec Only = no".

The g711a is fast to encode and decode. Using this codec again reduces your latency
and may make the echo less obvious or easier to catch with the echo canceller.

8. Power cycle the SPA-3000 (pull the power plug). Believe it or not, this sometimes fixes
the problem. Especially after you have changed the physical phone wiring.

9. Make some test calls. The telco test number 1800801920 is a good one to start with. It
has a recorded voice telling you your local phone number. While it's talking, talk back and
work out how much echo you are getting. Talk loud, talk soft.

10. Look at what you have got. If you can hear an echo then the problem could be that
your probably sending to much power down the line. This is probably reflecting back
somewhere as an echo. If you’re close to the exchange and have good wires then this is
probably the case. You need to crank back on the power. Go to PSTN -> "SPA To PSTN
Gain" and turn it down. Be aware that at some point if you turn it down to much, the SPA
sorts does a double negative and turns it way up. I believe the range of this variable is
about -127 -> 127 (from my testing). Turn it down, down, down, down until the person can
still hear you but reduced echo.

Note: if you enable "Echo Supp Enable" then you will negate these parameters. It seems
that the Sipura echo suppression is actually just an automatic gain control. It's really
annoying - leave it off.

11. Make a test call to someone with a known good phone out via the SPA's PSTN line or
get someone to call in to the PSTN line. Best if it’s just a boring old Telstra phone hard
wired to a socket on the wall. Don't call a mobile!

If the remote party is hearing echo, it could be that your phone is so loud that it's feeding
back into the microphone. Turn down the PSTN To SPA Gain until you can comfortable
hear the person, no more. If the remote user can still hear echo, try using a different
phone plugged into the SPA. Go for the basics first, a cruddy old Telstra phone is what I
use for testing. If this solves the problem you may have a bad phone or an impedance
miss match between your phone and the SPA.

• Try changing the Regional -> FXS Port Impedance to "600".

• Try changing the FXO port impedance to "600" or "global".

If this doesn't help, change it back. The impedance will only affect what the *remote* party
hears, it won't help echo you are hearing.

12. After you have the echo down to a reasonable level, go back into the "PSTN" tab and
switch on the "Echo Can Enable = yes". Check to see if the echo has improved. If the
echo is tolerable at this level, leave the adaptive echo canceller off. You should have the
echo level down to a level that can be stomped on by the echo canceller. If you are using
a sip device to talk through your PSTN line, you should probably do all the echo
cancellation at that device and leave it switched off in the SPA.

The adaptive echo canceller is a lot more aggressive but also can cancel out some of the
incoming conversation. In particular if you’re calling in a loud environment then the voice
going down the line from your end can trick the echo canceller to start canning some of
the real conversation. It makes the incoming party sound a bit scratchy. Leave it off
unless you really need it.

The "Echo Supp Enable" switches on automatic gain controls. This means the Sipura will
be constantly turning up and down the volume of the call for you and the remote party to

TRIXBOX-2 Without Tears Page 206 of 224

 try and keep the sound levels at a "good" level. Sipura's definition of good may not suit
your situation. The constant variation of the volume annoys me so I recommend leaving it
"off".

13. Test call. Talk loud, talk soft. Is your conversation clear at both ends? Should be a lot
better. If echo re-appears, at a later date, remember to try power cycling the SPA before
you tweak with anything. It may also be at the other end of the call.

In the end it basically boils down to this –

If you are hearing the echo, the real problem is at the *other* end of the connection. In a
normal phone conversation, the latency is so low that you don't notice it. Your brain
automatically tunes out to its own voice when you’re talking (as long as the delay between
talking and hearing isn't to long). When you insert the SPA, the delay is increased and
sometimes the echo can become noticeable.

The only way you can counter this is to reduce the latency (jitter buffer) and/or reduce the
gains so the echo volume is reduced below the level that it is noticed. At this point, the
SPA-3000 echo canceller should be able to kill off the rest.

E.4 Immediate Answer of PSTN Calls

By default, calls will be answered after about 3 rings thus allowing time for Asterisk to
detect the CID. Some users may want the PSTN calls to be answered by Asterisk
immediately especially if there is a common phone connected in parallel and to avoid
someone answering the call using the parallel phone.

To do this you need to change one setting in the zapata.conf file. By default the setting is
set to:

Immediate = no

To force Asterisk to answer immediately, change the line to read:

Immediate = yes

If you are not using Fax, it is also a good idea to disable fax extension in your General
setting.

This may or may not work satisfactorily as Asterisk needs a couple of rings to detect CID.

E.5 Rebuild Zaptel Driver (Users’ Suggestions)

E.5.1 As experienced by marner – a Whirlpool Forum participant.

On his Dell box, marner had to do the following to rebuild the driver and for it to work.

Log in as root and issue the following command:

cd /usr/src/kernels/2.6.9-34.EL-smp-i 686/include/linux
wget http://nerdvittles.com/aah27/spinlock.h

The rest of the procedure is as per earlier chapter Rebuilding Zaptel Driver

E.5.2 As suggested by Rob Thomas (the FreePBX guru)

Rob’s suggestion is to edit the file

TRIXBOX-2 Without Tears Page 207 of 224

 /usr/src/kernels/2.6.9-34.EL-i686/include/linux/spinlock.h
and change 'rw_lock_t' on line 407 to 'rwlock_t'

Once that is done, do the following:

rebuild-zaptel

That seems to be a lot easier.

 E.7 RAID1, LVM (logical volumes) – how to
(Submitted by a user: Rehan)

Introduction

According to Digium recommendations Asterisk boxes should be IDE based. This is

counter to what one would expect. However if you are using Zaptel drivers then a fast
hard disk or hardware RAID might ‘steal’ interrupts from the Zaptel drivers. Additionally
many hardware RAID solutions set themselves up on the PCI bus with timings that can
delay voice traffic to your voice cards.

(See note 3 at the end if you want to use scsi or sata drives)

For this particular application (A PBX) we are not too concerned about disk performance.
Much of the software will run in memory on a 300Mb Ram machine (Trixbox default install
consumes no more than 200Mb including the file cache). Fast hard discs improve
performance in systems that are heavily dependant on a swap file. Linux will keep
everything in memory + a reasonable file cache as much as possible. CPU performance
and making sure you have sufficient memory to run the PBX are the key performance
indicators of a healthy PBX.

We wouldn’t want to put an Asterisk box in production without some kind of resiliency to
survive continuous use over perhaps many years. To use an IDE disk based system we
can use software RAID to provide some protection and to make sure the PBX stays up
and running. The Raid subsystem can also email you if a drive fails.

The following procedure describes setting up a software RAID during installation on all
partitions of a Trixbox. This applies to a vanilla install from the Distribution CDROM.

We will be using RAID and also Logical Volume Management. Logical Volume
Management gives us the ability to dynamically resize drives and dynamically add disk
space on a live system without having to delete or create new partitions. So if your
requirements change in the future you can easily accommodate them.

The issues:

1. Implementing RAID and logical volumes post-install is complicated, dangerous and not
recommended.

2. RAID (hardware or software) and LVM are desirable features. IDE is still the cheapest
storage platform. This is especially true of Asterisk installs as many PBX's use low-end
hardware.

3. The default install of Trixbox does not allow any options to install RAID or LVM

4. The text mode Anaconda install does not allow manual configuration of Logical
volumes however a kickstart file does.

5. A kickstart install of RAID will always (!!!!) produce file system corruption if the software
RAID is not allowed to complete its first sync before the first reboot.

6. High end hardware RAID is still relatively expensive. Linux drivers are not always
available or if available, not always stable.

Point 5 will many times dissuade people from using software RAID and LVM. As long as
we can accommodate the first sync then we will have no problems.

Ok, lets get started:

TRIXBOX-2 Without Tears Page 210 of 224

 1) We’ll need to set-up the drives in a particular order:

Hardware configuration:

HD 1 connected to primary IDE as master.

HD 2 connected to secondary IDE as master.
CDROM connected to secondary IDE as slave.

The hard disks don't need to be exactly the same size. Actually using this method the
disks don't need to be the same size at all. I would recommend that the smallest disk be
at least 5Gigs. The Raid will configure itself to the smallest disk and the larger disk will
match up to the smaller disk’s partitions with any extra space left unused.

Although I worked this for IDE drives it can be used on any type of disk subsystem -
SCSI, sata etc with some modification for the drive labels.

2) Extract/Edit the CDROM:

Windows:

I used UltraISO on windows to modify the CDROM. Open the ISO with UltraISO and copy
the ks.cfg file somewhere. Remove the read only flag so you can edit it. It is very
important you edit the file with an editor that knows how to do Linux linefeeds. I
discovered and used Editpad pro for this. The lite (demo) version will suit the needs we
have. If your editor is not 100% compatible with Linux linefeeds after you reboot you will
get errors which have directory names with strange characters (/var/Trixbox_load^M/ or
/var/Trixbox_load/R where the /rR is actually in the directory name of load not a separate
directory)

Linux: (incomplete)

Extract the CDROM to a temporary Directory. Make the file ks.cfg as non-read only. Edit
and create the files as below. Use the following command to rebuild the ISO.

mkisofs -o modified-Trixbox.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -

boot-load-size 4 -boot-info-table

3) Get the Installation configuration file as follows:

We need to create a file that will tell the install program what to do. A copy of the existing
file is located in the root of the CDROM. It is called ks.cfg. Make a copy of this file and call
it ksRAIDlvm.cfg

4) Edit the ksRAIDlvm.cfg as follows

Delete the line where it says reboot. We don’t want it to automatically reboot at the end. !
This is a critical step!

Where it says:

#Partition clearing information

clearpart --all –initlabel
part /boot --fstype ext3 --size=100
part / --fstype ext3 --size=1024 –grow
part swap --size=256 --grow --maxsize=768

Replace with

TRIXBOX-2 Without Tears Page 211 of 224

 #Partition clearing information
clearpart --all –initlabel
part raid.01 --size=100 --ondisk=hda –asprimary
part raid.02 --size=100 --ondisk=hdc –asprimary
part swap --size=256 --ondisk=hda
part swap --size=256 --ondisk=hdc
part raid.11 --size=1 --grow --ondisk=hda
part raid.12 --size=1 --grow --ondisk=hdc
raid /boot --level=1 --device=md0 raid.01 raid.02
raid pv.01 --level=1 --device=md1 raid.11 raid.12
volgroup vg01 pv.01
logvol / --vgname=vg01 --size=10000 --name=root

Very important: the –asprimary switch must only appear on the raid.01 and raid.02
lines.

This will give you a 100MB RAID 1 /boot partition, two 256Mb swap partitions (change the
256 to a desirable size or replace with --recommended) and the rest of the disk will be a
logical volume (over laying a RAID1 ) containing the / (or root) filesystem. All partitions will
be formatted as Ext3 as normal. If you want to create other partitions to support other
uses you can change the raid.11 and raid.12 lines to read --size=xxxx (in megabytes) and
remove the –grow option. This will fix the size of the partition you create. After the
installation completes you can then go ahead and create more RAID1 partitions and
Logical volumes.

Where it says (in the section starting - %post)

mount /dev/hda /mnt/source

change to

mount /dev/md1 /mnt/source

Add the following lines to the end of the %post% section. This will update the boot
information to make both drives bootable. Remember to update the hdx numbers to
match your drive configuration.

/sbin/grub --batch <<EOT 1>/dev/null 2>/dev/null

root (hd0,0)
setup (hd0)
root (hd1,0)
setup (hd1)
quit
EOT

Save the file.

Add it to the root directory of the ISO and save the ISO under a different name.

Burn the new ISO to a CD. Boot your soon to be asterisk machine from this CD and use
the following command to start the install.

linux ks=cdrom:/ksRAID1lvm.cfg

The install process will continue as before however it will create the RAID as we have set-
up.

Begin the install. Let it run through to the end. When you see the REBOOT screen STOP.
Don't do anything here. We need to wait for the RAIDs to complete their first sync. For
IDE disks the only way I have found of reliably checking this is to wait for the drive light to

TRIXBOX-2 Without Tears Page 212 of 224

 go out. This can take some time depending on the speed of the disks and their size. Go
and have a coffee. If you have no other indication here just wait about half an hour/45
mins to be sure.

Once you are sure the disks are in sync. Reboot.

You are done!

Checking and maintaining:

Login as root using the password set-up during the earlier phase.

You can check the state of the RAID by using the following command:

cat /proc/mdstat

You should have two raids called md0 and md1. In square brackets for each it should say
[2/2]. Your disks are ready and Trixbox is installed. The block sizes may be different if you
are not using identical disks.

If it doesn't say [2/2] but the machine has restarted ok and it says [2/1] then one or both
your raids have not synced properly or your disk is faulty (bad blocks). To manually sync
the raids type some commands (for simplicity all the commands are included below. If a
partition is already in a Synced RAID the command will fail with an error (in this case the
error means success!). This you can ignore and move onto the next command):

mdadm -a /dev/md0 /dev/hda1

mdadm -a /dev/md0 /dev/hdc1
mdadm -a /dev/md1 /dev/hda3
mdadm -a /dev/md1 /dev/hdc3

use

watch cat /proc/mdstat

to monitor the raid re-build. Once it is complete you can issue the

reboot

command and restart the machine. Check your raids again with

cat /proc/mdstat

They should be ok now.

If the machine has not started ok (errors on the startup screen) then the chances are the
RAID was not completely built before the restart. The best idea here is to re-install this
time waiting longer before rebooting. It is difficult to know which files are not complete.

Notes:

1) In a VMWARE machine everything works fine. (To test this you need to create a
second hard drive when creating the virtual machine then do the install booting either off
the new CDROM or the new ISO).

2) For anyone who wants to revert (or vert) an existing drive to Raid, here is a good link:

http://linux-sxs.org/hardware/raid_for_idiots.html

Just ignore the last bit and use grub instead (Lilo is too old!!!!).

TRIXBOX-2 Without Tears Page 213 of 224

 The following commands achieve the same ends:

grub (enter)

root (hdx0,0)
setup (hdx0)
root (hdx1,0)
setup (hdx1)

(ctrl-z to exit)

3) This procedure will work for SCSI and SATA drives as well. Bearing in mind the
caveats Digium have about using IDE many people have successfully installed RAID 1 on
SCSI and SATA drives. To accomplish this replace the HDx with a suitable replacement
(usually hd0 is replaced with sd0 and hd1 with sd1).

If you have any issues booting from the RAID they can usually be fixed by booting from
the Trixbox CD and starting the Rescue Environment and running some commands:

Boot from the Trixbox CD. At the prompt type:

Linux rescue

Issue:

grub (enter)

root (hdx0,0)
setup (hdx0)
root (hdx1,0)
setup (hdx1)

(ctrl-z to exit)

reboot

We continue to use the textmode install because it reduces the chances of the install
failing. For example if you have a Rage XL video card then using a graphical install, the
format of the drives will fail (RAID or no RAID). In textmode logical volumes can only be
created in the kickstart file.

If your disk controller needs to have special drivers then the install must be started using
the following command:

Linux ks=cdrom:/ksRAIDlvm.cfg dd

At some point it will ask you for a driver disk. This can usually be obtained from the
manufacturers website.

Delete Call Records from CDR

There will be time when you need to delete the CDR records from your call details record.
One example is, those calls you made white testing will need to be deleted before going
live where you will need clean record.

• These records are being kept in the SQL database and to delete them, do the
following:
• From Tools Menu
• select phpmyadmin
• In the Database dropdown field, (top left), select the asteriskcdrdb.
Select the 'cdr' table in the tick box
• At the bottom of the list of table you will find a dropdown field “With Selected”,
select EMPTY
• You will be asks to 'confirm truncate table cdr',
• If you click Yes at this point the content of the table will be erased.

MySQL Manager – “tbm-phpmyadmin.noarch” must be installed. This can be done

through Packages. It is not installed by default. Without this you will not be able to
use phpadmin from the GUI.

Alternatively, you can do it manually;

Login to the shell (SSH) as root. You can do this using Putty.

Enter these commands manually, each on a new line.

mysql –p
Enter password: passw0rd
use asteriskcdrdb;
delete from cdr;
exit;

Your CDR will now be empty.

 Extension Numbers to avoid using
Unless you are prepared to edit and change some codes, its best to avoid the following
extension numbers:

200 - Park Notify

300-399 - Reserved for speed dial
666 - Reserved for FAX testing
70-79 - Reserved for calls on hold
700-799 - Reserved for calls on hold
7777 - Reserved extension for incoming calls simulation

sip_nat.conf
To those who use this configuration (not all do), I have an issue with externip = <DNS
name>. I wasn’t able to accept incoming calls although SIP was registered. Changing to
externip=<my fixed external IP> if you have a fixed IP or externhost=<DNS name> if
you don’t have a fixed IP and use Dynamic DNS service, solved the issue or do the
alternative as I have outlined below.

This issue may not be apparent at first as Asterisk will show that it is registered and you
will still be able to make a call out (except calls to another Asterisk that have this property
set). Another telltale sign is, you may not hear the ring tone when you are calling a party
or you may have audio problem.

This is caused by my /etc/hosts file where I have an entry (in red)

127.0.0.1 localhost
127.0.0.1 pcnovation.homelinux.org asterisk1.local

SipBroker will resolve pcnovation.homelinux.org as 127.0.0.1 which is what it is suppose

to be as it is being defined as such by the offending line. In actual fact
pcnovation.homelinux.org should be resolved to the external IP address. However I need
that entry for my VoiceMail e-mail notification since most email server will not accept
email from unknown source – grief time.

Taking my DNS name out solved the issue, but I cannot send e-mail notification of my
voicemail. To fix this problem (a kludge) I substituted pcnovation.homelinux.org with
another valid domain name different to my DynDNS domain name such as yahoo.com
thus:

127.0.0.1 yahoo.com asterisk1.local

and problem solved… for now until something else pops up ☺

Is the X100P installed?

At the command line, run lspci and amongst others, you should see the following;

00:0f.0 Communication controller: Motorola Wildcard X100P

Determine if there is any conflict with other PCI hardware. If there is, you probably will
need to replace or use another motherboard. If there is no conflict, make sure you have
the kernel sources installed and rebuild the zaptel component.

rebuild_zaptel

 genzaptelconf
ztcfg

Once done, run zttool on the command line to ensure the the card is functioning.

To confirm that zaptel is actually running, after reboot, log in to Asterisk and at the
command prompt issue the following command to configure zaptel.

genzaptelconf

After that restart amportal.

Amportal restart.

Using your browser on another PC, connect to TRIXBOX and using the Asterisk Info
option, check to see if zaptel is loaded.

Chances are, Zaptel will be found.

BUGS REPORTS
Software is not software if it is release without any bug. It just goes against nature’s logic,
not to mention our Mr. Murphy ☺

Asterisk re-load issue

After making changes to Trunks, IVR or DISA etc, the changes do not translate to the
system. This is due to an inherent bug in the Asterisk binary in Trixbox 1.2.

If this happens, run the following at the command prompt to force the reload:

asterisk -rx restart now

If the problem is related to Asterisk, this should get you going otherwise, it may be some
other gremlin that has gotten into the system.

Are you still having problem?

If you are still having problem installing Trixbox 1.2, it probably is time for you to do some
manual configuration as described in Rob Thomas’ blog.

Here is the link and as I have personally done it this way, I can assure you that it will
solve your problem – I hope ☺

Hangs on shutdown
Using X100P card caused Trixbox to hang on shutdown in Trixbox 2.0beta2. This
happened to me on 2 different make X100P. This does not happen with TDM400 card.

To avoid this hanging anomaly amportal stop must be executed before a reboot or
shutdown.

The following is the hack to stop the panic from occurring:

Log in as root:

Go to the /etc/rc.d directory.

cd /etc/rc.d

Rename all of the K92zaptel files to K95zaptel so that they are invoked after the
K94asterisk scripts:

mv rc0.d/K92zaptel rc0.d/K95zaptel
mv rc1.d/K92zaptel rc1.d/K95zaptel
mv rc2.d/K92zaptel rc2.d/K95zaptel
mv rc4.d/K92zaptel rc4.d/K95zaptel
mv rc6.d/K92zaptel rc6.d/K95zaptel

shutdown -r now

The system will now shutdown or reboot without a panic.

CHEAT SHEET
To restart Trixbox after configuration change without
amportal restart rebooting. However certain changes will need
rebooting.
asterisk -rvvvv To get to asterisk CLI
This works in custom context e.g.
• Voicemail(s2000@default) - will not play
default message
Disable default voicemail
• Voicemail(su2000@default) - will not play
message
default message and instead play your
unavailable custom message.

Enable Call waiting by default Edit ENABLECW=yes in amportal.conf

grep "AUTO FXO" /var/log/messages Tells you what mode your TDM400 is running on.
rpm -qa | grep asterisk Tells you what version of Aterisk is installed.
rpm -qa | grep zaptel-modules Tells you what Zaptel modules you have installed
To restart asterisk if required when something goes
service asterisk restart
wrong
To restart network service if connection goes down and
service network restart did not come up again even though internet has been
restored.
To reload SIP. This command is to be run from
sip reload
Asterisk CLI

EXPLOIT ALERTS
According to Computerworld, a vulnerability in the Asterisk PBX server that enables an
attacker to gain complete control of a PBX system has been discovered by an Australian
and New Zealand security outfit.

This was also highlighted by Ward Mundy of Nerd Vittle who said that he exploit allows an
attacker to spoof caller-IDs, sniff voice calls on the network and take complete control of
the system. This vulnerability has been identified in all versions of Asterisk included in
the Trixbox and Asterisk@Home releases except the new Asterisk 1.4 (currently still
under development).

An attacker who can connect to the Asterisk server SCCP “Skinny” port (by default
2000/tcp) can attack the vulnerable function prior to registering as a configured Skinny
phone, permitting pre-authentication remote compromise and remote code execution as
the root user.

To overcome this, simply block port 2000 tcp traffic through your firewall. Otherwise, if
your server is in the DMZ or connected to the Internet directly, then you should disable
the chan_skinny module. To do this, edit /etc/asterisk/modules.conf and add the following
line in the [modules] context.

noload => chan_skinny.so

Then restart Asterisk.

amportal restart

Note: This module is primarily used to talk to Cisco phones in their native language, i.e. non-SIP.
