IP Office IP Phone Installation Manual

Phone Security

There are a number of methods by which additional security can be implemented to ensure that on IP
phone does not adopt the identity of another.
• Disable Auto-Create Extension
Following installation, disabling Auto-Create Extn Enabled in the IP Office Manager System |
Gatekeeper tab stops new IP devices from assigning themselves as new extensions.
• Restrict the IP or MAC Address
Entering either of these values in the Extension's VoIP tab will restrict usage to that address or
device. The MAC address of an Avaya IP Telephone is printed on a label on the base of the
phone.
• Set a User Login Code
If a user Login Code is set, then any other IP device trying to log on as that extension must also
enter the correct login code. Note that if a login code is set, the user can use hot desk to log off
and log on elsewhere.

Listing Registered Phones

Using TFTP, a list can be obtained from the IP Office system of all the registered RAS users which
includes IP phones. For example:
1. In Windows select Start | Run and enter cmd for the Windows command line interpreter.
2. If necessary use cd commands to select the directory into which you want the list placed as the
current directory.
3. Enter
tftp -i xxx.xxx.xxx.xxx get nasystem/h323_ras_list yyyyyyyy.txt
•
xxx.xxx.xxx.xxx
•
yyyyyyy.txt is the name of a text file that doesn't already exist in that directory..
4. The TFTP command will confirm when the file has been successfully transferred.
5. Type exit to close the command line interpreter window.
6. Open the text file using Wordpad or a similar tool.
The IP Office Monitor application (Sysmon) can also show how many phones have registered and how
many are currently waiting to register. This appears as lines of the form:
792ms PRN: GRQ from c0a82c15 --- RAS reaches the maximum capacity of 10; Endpoints reistered 41
The System | Print trace filter option must be selected to see these and other IP phone registration
messages.
