IP Office Ports
Most PC firewalls will request the user to allow various exceptions when a newly installed application is first run.
However this may not always be the case, especially if the firewall is located elsewhere than the user's PC .
Adding Firewall Exceptions
The file avayafw.bat can be used to open up the necessary firewall exceptions for IP Office applications. The file can be
downloaded from http://marketingtools.avaya.com/knowledgebase/tools/firewall.
It only works for:
The default Windows XP/Windows 2003 firewall.
The application must be installed for the exception to be created.
The application must be installed in the default location.
Whilst avayafw.bat only works subject to the conditions above, for other firewalls study of this file will indicate the
necessary application files and ports for which exceptions need to be created.
Ports Used
The list below details many of the IP ports used by IP Office control units and IP Office applications. Many of these are
standard ports for different IP traffic protocols.

Ports
IP Office Monitor can be used to display IP packet details including the source and destination Port numbers. As well as
displaying the port numbers (in decimal), IP Office Monitor also displays the names of more commonly used ports
including IP Office specific ports.
For example "src = 23" is interpreted as "src = 23 (Telnet)".
The list below details the ports currently decoded by IP Office Monitor. For a full list of assigned non-IP Office ports see
