Phone Security; Listing Registered Phones - Avaya IP Office 3.2 Installation Manual

Phone Security

There are a number of methods by which additional security can be implemented to ensure that an 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 Address 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 IP phone 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
• 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 H.323 IP phones. For example:
Extn2602,2602,192.168.42.2,1720
ains600,2600,192.168.42.10,1026
Extn2601,2601,192.168.42.4,1720
New,2702,192.168.42.200,1720
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
where:
• xxx.xxx.xxx.xxx is the IP address of the IP Office unit.
• yyyyyyy.txt is the name of a text file that does not already exist in that directory.
The TFTP command will confirm when the file has been successfully transferred.
4. To close the command line interpreter window, type exit.
5. 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
registered 41
The System | Print trace filter option must be selected to see these messages.
