STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

An Overview of the Conference Station

The Cisco Unified IP Conference Station 7937G is a full-featured teleconference station that provides
voice communication over an Internet Protocol (IP) network. It functions much like a digital business
phone, allowing you to place and receive calls and to access features such as mute, hold, transfer,
speed dial, call forward, and more. In addition, because conference stations are connected to your data
network, they offer enhanced IP telephony features, including access to network information and
services, and customizable features and services. The conference stations also support certain security
features.
The conference station provides a backlit LCD screen, support for up to ten speed dial numbers, and a
variety of other sophisticated functions.
The conference station, like other network devices, must be configured and managed. The conference
stations encode G.711a, G.711u, G.729a, G.729ab, and decode all variants of G.711 and G.729. The
conference stations also support 16-bit/16-kHz wideband audio.

What Features are Supported on the Conference Station?

The conference station functions much like a digital business conference station, allowing you to place
and receive teleconference station calls. In addition to traditional telephony features, the conference
station includes features that enable you to administer and monitor the conference station as a network
device.
This section includes the following topics:
• Feature Overview, page 1-5
• Configuring Telephony Features, page 1-6
• Configuring Network Parameters Using the Conference Station, page 1-6
• Providing Users with Feature Information, page 1-7

Feature Overview
Conference stations provide traditional telephony functionality, such as call forwarding and transferring,
redialing, speed dialing, conference calling, and voice messaging system access. Conference stations
also provide a variety of other features. For an overview of the telephony features that the conference
station supports, see the “Telephony Features Available for the Conference Station” section on page 5-1.
As with other network devices, you must configure conference stations to prepare them to access
Cisco Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer
settings to configure on a conference station, but if your network requires it, you can manually configure
an IP address, TFTP server, and subnet mask. For instructions on configuring the network settings on
the conference station, see Chapter 4, “Configuring Settings on the Conference Station.”

 Chapter 1 An Overview of the Conference Station
What Features are Supported on the Conference Station?

The conference station can interact with other services and devices on your IP network to provide
enhanced functionality. For example, you can use XML to enable users to access information such as
weather, stocks, quote of the day, and other web-based information. For information about configuring
such services, see the “Configuring Corporate and Personal Directories” section on page 5-6 and the
“Setting Up Services” section on page 5-8.
Finally, because the conference station is a network device, you can obtain detailed status information
from it directly. This information can assist you with troubleshooting any problems users might
encounter when using their conference stations. See Chapter 7, “Viewing Model Information, Status, and
Statistics on the Conference Station,” for more information.

Preparing to Install the Conference Station on
Your Network

The Cisco Unified IP Conference Station 7937G enables you to communicate using voice over a data
network. To provide this capability, the conference stations depend upon and interact with several other
key Cisco Internet Protocol (IP) Telephony and network components, including Cisco Unified
Communications Manager 6.0, Domain Name System (DNS) and Dynamic Host Configuration Protocol
(DHCP) servers, Trivial File Transfer Protocol (TFTP) servers, media resources, and so on.
This chapter focuses on the interactions between the conference station and Cisco Unified
Communications Manager, DNS and DHCP servers, TFTP servers, and switches. It also describes
options for powering conference stations.
For related information about voice and IP communications, refer to this URL:
http://www.cisco.com/en/US/partner/products/sw/voicesw/index.html
This chapter provides an overview of the interaction between the conference station and other key
components of a Voice over IP (VoIP) network. It covers these topics:

Understanding How the Conference Station Interacts with Cisco Unified

Communications Manager
Cisco Unified Communications Manager is an open and industry-standard call processing system.
Cisco Unified Communications Manager software sets up and tears down calls between
conference stations, integrating traditional private branch exchange (PBX) functionality with the
corporate IP network. Cisco Unified Communications Manager manages the components of the IP
telephony system—the conference stations, the access gateways, and the resources necessary for such
features as call conferencing and route planning. Cisco Unified Communications Manager also provides:
• Firmware for conference stations
• Authentication and encryption (if configured for the telephony system)
• Configuration file
• Conference station registration
• Call preservation, so that a media session continues if signaling is lost between the primary
Cisco Unified Communications Manager and a conference station
For information about configuring Cisco Unified Communications Manager to work with the IP devices
described in this chapter, refer to Cisco Unified Communications Manager Administration Guide,
Cisco Unified Communications Manager System Guide, and to Cisco Unified Communications Manager
Security Guide.
For an overview of security functionality for the conference station, see the “Understanding Security
Features for Conference Stations” section on page 1-7.

Note If the conference station model that you want to configure does not appear in the Phone Type drop-down
list in Cisco Unified Communications Manager Administration, go to the following URL and install the
latest support patch for your version of Cisco Unified Communications Manager:

Providing Power to the Conference Station

The conference station can be powered with external power or with Power over Ethernet (PoE). External
power is provided through a separate power supply. PoE is provided by a switch through the Ethernet
cable attached to a conference station.

Note When you install a conference station that is powered by an optional external power supply, do the
following:
• Use a power interface cable to attach to the PoE cable and LAN wall port. See the “Installing the
Conference Station” section on page 3-4 for instructions on how to attach the power interface cable.
• Connect the power supply to the conference station and to a power outlet before you connect the
Ethernet cable to the conference station. When you remove a conference station that is powered with
external power, disconnect the Ethernet cable from the conference station before you disconnect the
power supply.

Understanding Conference Station Configuration Files

Configuration files for a conference station are stored on the TFTP server and define parameters for
connecting to Cisco Unified Communications Manager. In general, any time you make a change in
Cisco Unified Communications Manager that requires the conference station to be reset, a change is
made to the conference station’s configuration file automatically.
Configuration files also contain information about which image load the conference station should be
running. If this image load differs from the one currently loaded on a conference station, the conference
station contacts the TFTP server to request the required load files.

 Chapter 2 Preparing to Install the Conference Station on Your Network
Understanding the Conference Station Startup Process

A conference station accesses a default configuration file named XmlDefault.cnf.xml from the TFTP
server when these conditions exist:
• You have enabled auto-registration in Cisco Unified Communications Manager
• The conference station has not been added to the Cisco Unified Communications Manager Database
• The conference station is registering for the first time
If auto registration is not enabled and the conference station has not been added to the
Cisco Unified Communications Manager Database, the conference station registration request will be
rejected. In this case, the conference station will reset and attempt to register repeatedly.
If the conference station has registered before, the conference station will access the configuration file
named SEPmac_address.cnf.xml, where mac_address is the Media Access Control (MAC) address of
the conference station.

Understanding the Conference Station Startup Process

When connecting to the VoIP network, the conference station goes through a standard startup process,
as described in Table 2-4. Depending on your specific network configuration, not all of these process
steps may occur on your conference station.

Table 2-4 Conference Station Startup Process

Adding Conference Stations with Auto-Registration

By enabling auto-registration before you begin installing conference stations, you can:
• Automatically add a conference station to the Cisco Unified Communications Manager database
when you physically connect the conference station to your IP telephony network. During
auto-registration, Cisco Unified Communications Manager assigns the next available sequential
directory number to the conference station.
• Add conference stations without first gathering MAC addresses from the conference stations.

Adding Conference Stations to the Cisco Unified Communications Manager Database

Note You should use auto-registration to add less than 100 conference stations to your network. To add more
than 100 conference stations to your network, use BAT. See the “Adding Conference Stations with BAT”
section on page 2-9.

In some cases, you might not want to use auto-registration: for example, if you want to assign a specific
directory number to the conference station or if you plan to implement authentication or encryption, as
described in Cisco Unified Communications Manager Security Guide.
For information about enabling auto-registration, refer to “Enabling Auto-Registration” in the
Cisco Unified Communications Manager Administration Guide.

Adding Conference Stations with Auto-Registration and TAPS

You can add conference stations with auto-registration and TAPS without first gathering MAC addresses
from conference stations.
TAPS works with BAT to update a batch of conference stations that were already added to the
Cisco Unified Communications Manager database with dummy MAC addresses. You use TAPS to
update MAC addresses and download pre-defined configurations for conference stations.

Note Cisco recommends you use auto-registration and TAPS to add less than 100 conference stations to your
network. To add more than 100 conference stations to your network, use the Bulk Administration Tool
(BAT). See the “Adding Conference Stations with BAT” section on page 2-9.

To implement TAPS, you or the end-user dial a TAPS directory number and follow voice prompts. When
the process is complete, the conference station will have downloaded its directory number and other
settings, and the conference station will be updated in Cisco Unified Communications Manager
Administration with the correct MAC address.
Auto-registration must be enabled in Cisco Unified Communications Manager Administration for TAPS
to function.
Refer to Cisco Unified Communications Manager Bulk Administration Guide for detailed instructions
about BAT and TAPS.

Configuring Corporate and Personal Directories

The Directories button on the conference station gives users access to several directories. These
directories can include:
• Corporate Directory—Allows a user to look up conference station numbers for co-workers.
To support this feature, you must configure corporate directories. For more information, see the
“Configuring Corporate Directories” section on page 5-6.
• Personal Directory—Allows a user to store a set of personal numbers.
To support this feature, you must provide the user with software to configure the personal directory.
For more information, see the “Configuring Personal Directory” section on page 5-7.

Configuring Corporate Directories

Cisco Unified Communications Manager uses a Lightweight Directory Access Protocol (LDAP)
directory to store authentication and authorization information about users of Cisco Unified
Communications Manager applications that interface with Cisco Unified Communications Manager.
Authentication establishes a user’s right to access the system. Authorization identifies the telephony
resources that a user is permitted to use, such as a specific teleconference station extension.

Customizing the Conference Station

This chapter explains how you customize configuration files, Cisco Unified IP Conference
Station 7937G ring sounds, and the idle display at your site. Ring sounds play when the conference
station receives a call. The idle display appears on the LCD screen when the conference station has not
been used for a designated period.
This chapter includes these topics:
• Customizing and Modifying Configuration Files, page 6-1
• Creating Custom Conference Station Rings, page 6-2
• Configuring the Idle Display, page 6-4

Customizing and Modifying Configuration Files

You can modify configuration files (for example, edit the xml files) and add customized files
(for example, custom ring tones and call back tones) to the Trivial File Transfer Protocol (TFTP)
directory. You can modify files and add customized files to the TFTP directory in Cisco IPT Platform
Administration from the TFTP Server File Upload page. Refer to Cisco Unified Communications
Operating System Administration Guide for information about how to upload files to the TFTP folder in

Creating Custom Conference Station Rings

Creating Custom Conference Station Rings

The conference station ships with two default ring types that are implemented in hardware: Chirp1 and
Chirp2. Cisco Unified Communications Manager also provides a default set of additional conference
station ring sounds that are implemented in software as pulse code modulation (PCM) files. The PCM
files, along with an XML file (named Ringlist.xml) that describes the ring list options that are available
at your site, exist in the TFTP directory on each Cisco Unified Communications Manager.
For more information, refer to Cisco Unified Communications Manager System Guide, Release 5.1(1),
“Cisco TFTP” chapter, and Cisco Unified Communications Operating System Administration Guide,
“Software Upgrades” chapter.
The following sections describe how you can customize the conference station rings that are available at
your site by creating PCM files and editing the Ringlist.xml file:
• Ringlist.xml File Format Requirements, page 6-2
• PCM File Requirements for Custom Ring Types, page 6-3
• Configuring a Custom Conference Station Ring, page 6-3

Ringlist.xml File Format Requirements

The Ringlist.xml file defines an XML object that contains a list of conference station ring types. This
file can include up to 50 ring types. Each ring type contains a pointer to the PCM file that is used for that
ring type and the text that will appear on the Ring Type menu on a conference station for that ring. The
Cisco TFTP server for each Cisco Unified Communications Manager contains this file.
The CiscoIPconference stationRingList XML object uses the following simple tag set to describe the
information:
<CiscoIPconference stationRingList>
<Ring>
<DisplayName/>
<FileName/>
</Ring>
</CiscoIPconference stationRingList>

The following characteristics apply to the definition names. You must include the required DisplayName
and FileName for each conference station ring type.
• DisplayName defines the name of the custom ring for the associated PCM file that will display on
the Ring Type menu of the conference station.
• FileName specifies the name of the PCM file for the custom ring to associate with DisplayName.

Note The DisplayName and FileName fields must not exceed 25 characters.

This example shows a Ringlist.xml file that defines two conference station ring types:
<CiscoIPconference stationRingList>
<Ring>
<DisplayName>Analog Synth 1</DisplayName>
<FileName>Analog1.raw</FileName>
</Ring>
<Ring>
<DisplayName>Analog Synth 2</DisplayName>

The PCM files for the ring types must meet the following requirements for proper playback on
conference stations:
• Raw PCM (no header)
• 8000 samples per second
• 8 bits per sample
• uLaw compression
• Maximum ring size is 16080 samples
• Minimum ring size is 240 samples
• Number of samples in the ring is evenly divisible by 240.
• Ring starts and ends at the zero crossing
• To create PCM files for custom conference station rings, you can use any standard audio editing
packages that support these file format requirements

Configuring a Custom Conference Station Ring

To create custom conference station rings for the conference station, follow these steps:

Procedure

Step 1 Create a PCM file for each custom ring (one ring per file). Ensure the PCM files comply with the format
guidelines that are listed in the “PCM File Requirements for Custom Ring Types” section on page 6-3.
Step 2 Upload the new PCM files that you created to the Cisco TFTP server for each
Cisco Unified Communications Manager in your cluster. For more information, refer to
Cisco Unified Communications Operating System Administration Guide, “Software Upgrades” chapter.
Step 3 Use a text editor to edit the Ringlist.xml file. See the “Ringlist.xml File Format Requirements” section
on page 6-2 for information about how to format this file and for a sample Ringlist.xml file.
Step 4 Save your modifications and close the Ringlist.xml file.
Step 5 Cache the new Ringlist.xml file:
a. Log on to Cisco Unified Communications Manager Administration.
b. From the Navigation drop-down list at the top right of the window, select

Resolving Startup Problems

Symptom: The Conference Station Does Not Go Through its Normal Startup
Process
When you connect a conference station into the network port, the conference station should go through
its normal startup process as described in the “Verifying the Conference Station Startup Process” section
on page 3-8, and the LCD screen should display information. If the conference station does not go
through the startup process, the cause may be faulty cables, bad connections, network outages, lack of
power, and so on. Or, the conference station may not be functional.
To determine whether the conference station is functional, follow these suggestions to systematically
eliminate these other potential problems:
1. Verify that the network port is functional:
– Exchange the Ethernet cables with cables that you know are functional.
– Disconnect a functioning conference station from another port and connect it to this network
port to verify the port is active.
– Connect the conference station that will not start up to a different network port that is known to
be good.
– Connect the conference station that will not start up directly to the port on the switch,
eliminating the patch panel connection in the office.
2. Verify that the conference station is receiving power:
– If you are using external power, verify that the electrical outlet is functional.
– If you are using in-line power, use the external power supply instead.
– If you are using the external power supply, switch with a unit that you know to be functional.
3. If the conference station still does not start up properly, perform a factory reset of the conference
station. For instructions, see the “Performing a Factory Reset” section on page 9-12.
If after attempting these solutions, the LCD screen on the conference station does not display any
characters after at least five minutes, contact a Cisco technical support representative for additional
assistance.

Symptom: The Conference Station Does Not Register with Cisco Unified
Communications Manager
To start up properly, the conference station must be connected to the Ethernet network and registered
with a Cisco Unified Communications Manager. If the conference station does not start up properly,
review the following sections:
• Checking Network Connectivity, page 9-4
• Verifying TFTP Server Settings, page 9-4
• Verifying IP Addressing and Routing, page 9-4
• Verifying DNS Settings, page 9-4
• Verifying Cisco Unified Communications Manager Settings, page 9-5

 Chapter 9 Troubleshooting and Maintenance
Resolving Startup Problems

Checking Network Connectivity

If the network is down between the conference station and the TFTP server or
Cisco Unified Communications Manager, the conference station cannot start up properly. Ensure that the
network is currently running.

Verifying TFTP Server Settings

You can determine the IP address of the TFTP server used by the conference station by choosing
Applications > Settings > Network Configuration, and then scrolling to the TFTP Server 1 option.
If you have assigned a static IP address to the conference station, you must manually enter a setting for
the TFTP Server 1 option. See the “Network Configuration Menu” section on page 4-5.
If you are using Dynamic Host Configuration Protocol (DHCP), the conference station obtains the
address for the Trivial File Transfer Protocol (TFTP) server from the DHCP server. A valid TFTP server
must be set in DHCP option 150 or option 66 on the DHCP server.
You can also enable the conference station to use an alternate TFTP server. Such a setting is particularly
useful if the conference station was recently moved from one location to another. See the “Network
Configuration Menu” section on page 4-5 for instructions.

Verifying IP Addressing and Routing

You should verify the Internet Protocol (IP) addressing and routing settings on the conference station. If
you are using DHCP, the DHCP server should provide these values. If you have assigned a static IP
address to the conference station, you must enter these values manually.
On the conference station, choose Applications > Settings > Network Configuration, and look at the
following options:
• DHCP Server—If you have assigned a static IP address to the conference station, you do not need
to enter a value for the DHCP Server option. However, if you are using a DHCP server, this option
must have a value. If it does not, check your IP routing and VLAN configuration. Refer to
Troubleshooting Switch Port Problems, available at this URL:
http://www.cisco.com/warp/customer/473/53.shtml
• IP Address, Subnet Mask, Default Router—If you have assigned a static IP address to the conference
station, you must manually enter settings for these options. See the “Network Configuration Menu”
section on page 4-5 for instructions.
If you are using DHCP, check the IP addresses distributed by your DHCP server. Refer to Understanding
and Troubleshooting DHCP in Catalyst Switch or Enterprise Networks, available at this URL:
http://www.cisco.com/warp/customer/473/100.html#41

Verifying DNS Settings

If you are using DNS to refer to the TFTP server or to Cisco Unified Communications Manager, you
must ensure that you have specified a Domain Name System (DNS) server. Verify this setting by
choosing Applications > Settings > Network Configuration, and scrolling to the DNS Server 1 option.
You should also verify that there is a CNAME entry in the DNS server for the TFTP server and for
Cisco Unified Communications Manager.
You must also ensure that DNS is configured to do reverse look-ups.

 Chapter 9 Troubleshooting and Maintenance
Resolving Startup Problems

Verifying Cisco Unified Communications Manager Settings

On the conference station, choose Applications > Settings > Device Configuration >
CallManager Configuration, and look at the CallManager 1–5 options. The conference station
attempts to open a Transmission Control Protocol (TCP) connection to all the Cisco Unified
Communications Manager servers that are part of the assigned Cisco Unified Communications Manager.
If none of these options contain IP addresses or show Active or Standby, the conference station is not
properly registered with Cisco Unified Communications Manager. See the “Registering the Conference
Station with Cisco Unified Communications Manager” section on page 9-6 for tips on resolving this
problem.

Cisco Unified Communications Manager and TFTP Services Are Not Running
If the Cisco Unified Communications Manager or TFTP services are not running, conference stations
may not be able to start up properly. However, in such a situation, it is likely that you are experiencing
a system-wide failure and that other conference stations and devices are unable to start up properly.
If the Cisco Unified Communications Manager service is not running, all devices on the network that
rely on it to make conference station calls will be affected. If the TFTP service is not running, many
devices will not be able to start up successfully.
To start a service, follow these steps:

Procedure

Step 1 From Cisco Unified Communications Manager Administration, choose Cisco Unified Serviceability
from the Navigation drop-down list that displays in the upper, right corner of the window, and then
click Go.
Step 2 Choose Tools > Control Center - Network Services.
Step 3 Choose the primary Cisco Unified Communications Manager server from the Server drop-down list.
The page displays the service names for the server that you chose, the status of the services, and a service
control panel to stop or start a service.
Step 4 If a service has stopped, click its radio button, and then click Start.

Creating a New Configuration File

If you continue to have problems with a particular conference station that other suggestions in this
chapter do not resolve, the configuration file may be corrupt.
To create a new configuration file, follow these steps:

Procedure

Step 1 In Cisco Unified Communications Manager Administration, choose Device > Phone. Enter search
criteria to locate the conference station experiencing problems, and then click the device name.
Step 2 In the Phone Configuration window, click Delete to remove the conference station from
Cisco Unified Communications Manager.

Cisco Unified IP Conference Station 7937G Administration Guide for Cisco Unified Communications Manager 6.0
OL-11560-01 Rev. B0 9-5
 Chapter 9 Troubleshooting and Maintenance
Resolving Startup Problems

Step 3 Add the conference station back to Cisco Unified Communications Manager. See the
“Adding Conference Stations to the Cisco Unified Communications Manager Database” section on
page 2-7 for details.
Step 4 Power cycle the conference station.

Note When you remove a conference station from the Cisco Unified Communications Manager database, its
configuration file is deleted from the Cisco Unified Communications Manager TFTP server. The
conference station’s directory number remains in the Cisco Unified Communications Manager. It
becomes an “unassigned DN” and can be used by another device. If unassigned DNs are not used by
other devices, delete them from Cisco Unified Communications Manager. You can use the Route Plan
Report to view and delete unassigned reference numbers. Refer to Cisco Unified Communications
Manager Administration Guide for more information.

Registering the Conference Station with Cisco Unified Communications Manager

A conference station can register with a Cisco Unified Communications Manager server only if the
conference station has been added to the server or if auto-registration is enabled. Review the information
and procedures in the “Adding Conference Stations to the Cisco Unified Communications Manager
Database” section on page 2-7 to ensure that the conference station has been added to
Cisco Unified Communications Manager.
To verify that the conference station is in the Cisco Unified Communications Manager database, choose
Device > Phone from Cisco Unified Communications Manager Administration and search for the
conference station based on its MAC Address. For information about determining a MAC address, see
the “Determining the MAC Address of a Conference Station” section on page 2-9.
If the conference station is already in the Cisco Unified Communications Manager database, its
configuration file may be damaged. See the “Creating a New Configuration File” section on page 9-5 for
assistance.

Symptom: Conference Station Unable to Obtain IP Address

If a conference station is unable to obtain an IP address when it starts up, the conference station may not
be on the same network or VLAN as the DHCP server, or the switch port to which the conference station
is connected may be disabled.
Make sure that the network or VLAN to which the conference station is connected has access to the
DHCP server, and make sure that the switch port is enabled.

Conference Station Resets Unexpectedly

Conference Station Resets Unexpectedly

If users report that their conference stations are resetting during calls or while idle on their desk, you
should investigate the cause. If the network connection and Cisco Unified Communications Manager
connection are stable, a conference station should not reset on its own.
Typically, a conference station resets if it has problems connecting to the Ethernet network or to
Cisco Unified Communications Manager. These sections can help you identify the cause of a conference
station resetting in your network:
• Verifying Physical Connection, page 9-7
• Identifying Intermittent Network Outages, page 9-7
• Verifying DHCP Settings, page 9-7
• Checking Static IP Address Settings, page 9-8
• Verifying Voice VLAN Configuration, page 9-8
• Eliminating DNS or Other Connectivity Errors, page 9-8
• Checking Power Connection, page 9-9

Verifying Physical Connection

Verify that the Ethernet connection to which the conference station is connected is up. For example,
check if the particular port or switch to which the conference station is connected is down and that the
switch is not rebooting. Also make sure that there are no cable breaks.

Identifying Intermittent Network Outages

Intermittent network outages affect data and voice traffic differently. Your network might have been
experiencing intermittent outages without detection. If so, data traffic can resend lost packets and verify
that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather
than retransmitting a lost network connection, the conference station resets and attempts to reconnect its
network connection.
If you are experiencing problems with the voice network, you should investigate whether an existing
problem is simply being exposed.

Verifying DHCP Settings

Follow this process to help determine if the conference station has been properly configured to use
DHCP:
1. Verify that you have properly configured the conference station to use DHCP. See the
“Network Configuration Menu” section on page 4-5 for more information.
2. Verify that the DHCP server has been set up properly.
3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.
Conference stations send messages with request type 151 to renew their DHCP address leases. If the
DHCP server expects messages with request type 150, the lease will be denied, forcing the
conference station to restart and request a new IP address from the DHCP server.

Conference Station Resets Unexpectedly

Checking Static IP Address Settings

If the conference station has been assigned a static IP address, verify that you have entered the correct
settings. See the “Network Configuration Menu” section on page 4-5 for more information.

Verifying Voice VLAN Configuration

If the conference station appears to reset during heavy network usage (for example, following extensive
web surfing on a computer connected to the same switch as conference station), it is likely that you do
not have a voice VLAN configured.
Isolating the conference stations on a separate auxiliary VLAN increases the quality of the voice traffic.
See the “Understanding Interactions with Other Cisco Unified IP Communications Products” section on
page 2-1 for details.

Eliminating DNS or Other Connectivity Errors

If the conference station continues to reset, follow these steps to eliminate DNS or other connectivity
errors:

Procedure

Step 1 Use the Erase softkey to reset conference station settings to their default values. See the “Resetting or
Restoring the Conference Station” section on page 9-11 for details.
Step 2 Modify DHCP and IP settings:
a. Disable DHCP.
b. Assign static IP values to the conference station. Use the same default router setting used for other
functioning conference stations.
c. Assign TFTP server. Use the same TFTP server used for other functioning conference stations.
See the “Network Configuration Menu” section on page 4-5 for instructions on modifying the above
three settings.
Step 3 On the Cisco Unified Communications Manager server, verify that the local host files have the correct
Cisco Unified Communications Manager server name mapped to the correct IP address.
Step 4 From Cisco Unified Communications Manager Administration, choose System > Server to locate the
server, and then click the server name. Verify that the server is referred to by its IP address and not by
its DNS name.
Step 5 From Cisco Unified Communications Manager Administration, choose Device > Phone to locate the
conference station, and then click the conference station name. Verify that you have assigned the correct
MAC address to this conference station. For information about determining a MAC address, see the
“Determining the MAC Address of a Conference Station” section on page 2-9.
Step 6 Power cycle the conference station.

General Troubleshooting Tips

Checking Power Connection

In most cases, a conference station will restart if it powers up using external power but loses that
connection and switches to Power over Ethernet (PoE). Similarly, a conference station may restart if it
powers up using PoE and then gets connected to an external power supply.

General Troubleshooting Tips

This section provides troubleshooting information for some common issues that might occur on the
conference station.
Table 9-1 provides general troubleshooting information for the conference station.

Table 9-1 Cisco Unified IP Conference Station 7937G Troubleshooting

Summary Explanation
Changing the conference station By default, the network configuration options are locked to
configuration prevent users from making changes that could impact their
network connectivity. You must unlock the network
configuration options before you can configure them. See the
“Unlocking and Locking Options” section on page 4-3 for
details.
Codec mismatch between the The RxType and the TxType statistics show the codec that is
conference station and another being used for a conversation between this conference station
device and the other device. The values of these statistics should
match. If they do not, verify that the other device can handle the
codec conversation or that a transcoder is in place to handle the
service.
See the “Call Statistics Screen” section on page 7-4 for
information about displaying these statistics.
Dual-Tone Multi-Frequency (DTMF) When you are on a call that requires keypad input, if you press
delay the keys too quickly, some of them might not be recognized.
Gaps in voice calls Check the Avg Jitter and the Max Jitter statistics. A large
variance between these statistics might indicate a problem with
jitter on the network or periodic high rates of network activity.
See the “Call Statistics Screen” section on page 7-4 for
information about displaying these statistics.
Conference station does not ring Check that the ringer setting is not “Ringer Off.” Check the
volume level.
LCD display issues If the LCD screen appears to have rolling scan lines (beat
frequencies) or a wavy pattern, it might be interacting with
certain types of older fluorescent lights in the building. Moving
the conference station away from the lights, or replacing the
lights, should resolve the problem.

Summary Explanation
Loopback condition A loopback condition can occur when the following conditions
are met:
• The conference station receives power from an external
power supply
• The conference station is powered down (the power supply
is disconnected)
In this case, the switch port on the conference station can
become disabled and the following message will appear in the
switch console log:
HALF_DUX_COLLISION_EXCEED_THRESHOLD
To resolve this problem, re-enable the port from the switch.
Moving a network connection from If you are powering your conference station through the
the conference station to a network connection, you must be careful if you decide to
workstation unplug the conference station’s network connection and plug
the cable into a desktop computer.

Caution The computer’s network card cannot receive power

through the network connection; if power comes
through the connection, the network card can be
destroyed. To protect a network card, wait 10
seconds or longer after unplugging the cable from
the conference station before plugging it into a
computer. This delay gives the switch enough time to
recognize that there is no longer a conference station
on the line and to stop providing power to the cable.

No dial tone Check that all connections are secure and in place. Make sure
all connections are correct.
No LCD screen display Check to make sure that the conference station has power.
Make sure that the power supply unit is plugged in.
One-way audio When at least one person in a call does not receive audio, IP
connectivity between conference stations is not established.
Check the configurations in routers and switches to ensure that
IP connectivity is properly configures.

Resetting or Restoring the Conference Station

There are two methods for resetting or restoring the conference station:
• Performing a Basic Reset, page 9-11
• Performing a Factory Reset, page 9-12

Performing a Basic Reset

Performing a basic reset of a conference station provides a way to recover if the conference station
experiences an error. A basic reset resets or restores various configuration and security settings.
Table 9-2 describes the ways to perform a basic reset. You can reset a conference station with any of
these operations any time after the conference station has started up. Choose the operation that is
appropriate for your situation.

Using the Quality Report Tool

Using the Quality Report Tool

The Quality Report Tool (QRT) is a voice quality and general problem-reporting tool for the conference
station. The QRT feature is installed as part of Cisco Unified Communications Manager.
You can configure users’ conference stations with QRT. When you do so, users can report problems with
conference station calls by pressing the QRT softkey. This softkey is available only when the conference
station is in the Connected, Connected Conference, Connected Transfer, and/or OnHook states.
When a user presses the QRT softkey, a list of problem categories appears. The user selects the
appropriate problem category and this feedback is logged in an XML file. Actual information logged
depends on the user selection and whether the destination device is a conference station.
For more information about using QRT, refer to Cisco Unified Communications Manager Features and
Services Guide.

Monitoring the Voice Quality of Calls

To measure the voice quality of calls that are sent and received within the network, conference stations
use these statistical metrics that are based on concealment events. The DSP plays concealment frames
to mask frame loss in the voice packet stream.
• Concealment Ratio metrics—Show the ratio of concealment frames over total speech frames. An
interval conceal ratio is calculated every 3 seconds.
• Concealed Second metrics—Show the number of seconds in which the DSP plays concealment
frames due to lost frames. A severely “concealed second” is a second in which the DSP plays more
than five percent concealment frames.
• MOS-LQK metrics—Use a numeric score to estimate the relative voice listening quality. The
conference station calculates the mean opinion score (MOS) for listening quality (LQK) based
audible concealment events due to frame loss in the preceding 8 seconds, and includes perceptual
weighting factors such as codec type and frame size.
MOS LQK scores are produced by a Cisco proprietary algorithm that is an implementation of
P.VTQ, an ITU provisional standard.

Note Concealment ratio and concealment seconds are primary measurements based on frame loss while
MOS LQK scores project a “human-weighted” version of the same information on a scale from
5 (excellent) to 1 (bad) for measuring listening quality.

Listening quality scores (MOS LQK) relate to the clarity or sound of the received voice signal.
Conversational quality scores (MOS CQ such as G.107) include impairment factors, such as delay, that
degrade the natural flow of conversation.
For information about configuring voice quality metrics for conference stations, refer to Cisco Unified
Communications Manager System Guide, “Cisco Unified IP Phones” chapter, “Phone Features” section.
You can access voice quality metrics from the conference station by using the Call Statistics screen
(see the “Call Statistics Screen” section on page 7-4) or remotely by using Streaming Statistics
(see Chapter 8, “Monitoring the Conference Station Remotely”).
To use the metrics for monitoring voice quality, note the typical scores under normal conditions of zero
packet loss, and use the metrics as a baseline for comparison.

Cisco Unified IP Conference Station 7937G Administration Guide for Cisco Unified Communications Manager 6.0
OL-11560-01 Rev. B0 9-13
 Chapter 9 Troubleshooting and Maintenance
Resolving Conference Call Reception Problems

It is important to distinguish significant changes from random changes in metrics. Significant changes
are scores that change about 0.2 MOS or greater and persist in calls that last longer than 30 seconds.
Conceal Ratio changes should indicate greater than 3 percent frame loss.
MOS LQK scores can vary based on the codec that the conference station uses. The following codecs
provide these maximum MOS LQK scores under normal conditions with zero frame loss:
• G.711 codec gives 4.5 score
• G.719A/ AB gives 3.7 score
A Conceal Ratio of zero indicates that the IP network is delivering frames and packets on time with no
loss.
When you observe significant and persistent changes to metrics, use Table 9-3 for general
troubleshooting information.

Table 9-3 Changes to Voice Quality Metrics

Metric Change Condition

MOS LQK scores decrease Network impairment from packet loss or high jitter:
significantly • Average MOS LQK decreases could indicate widespread and
uniform impairment.
• Individual MOS LQK decreases indicate bursty impairment.
Cross-check with Conceal Ratio and Conceal Seconds for
evidence of packet loss and jitter.
MOS LQK scores decrease • Check to see if the conference station is using a different
significantly codec than expected (RxType and TxType).
• Check to see if the MOS LQK version changed after a
firmware upgrade.
Conceal Ratio and Conceal • Network impairment from packet loss or high jitter.
Seconds increase significantly
Conceal Ratio is near or at zero, • Noise or distortion in the audio channel such as echo or audio
but the voice quality is poor levels.
• Tandem calls that undergo multiple encode/decode such as
calls to a cellular network or calling card network.
Check packet transmit (TxCnt) and packet receive (RxCnt)
counters to verify that voice packets are flowing.

Note Voice quality metrics do not account for noise or distortion, only frame loss.

Resolving Conference Call Reception Problems

To ensure optimum performance with the conference station and the external microphones, see
“Guidelines for Best Performance” section on page 3-9 and the “Conference Room Setup Examples”
section on page 3-10.
