Error Conditions
Issue 5 April 2010 19
The 1600 Series IP Telephones support a feature called Unnamed Registration. Unnamed
Registration allows a telephone to register with the Avaya Media Server without an extension,
assuming the Avaya Media Server also supports this feature. To invoke Unnamed Registration,
take no action. Allow the Extension... prompt to display for 60 seconds without making an
entry. The telephone automatically attempts to register by means of Unnamed Registration. A
telephone registered with Unnamed Registration has the following characteristics:
●only one call appearance,
●no administrable features,
●can make only outgoing calls, subject to call server Class of Restriction/Class of Service
limitations, and
●can be converted to normal “named” registration by the user entering a valid extension and
password (that is, logging in).
Note:
Note: Unnamed Registration requires administration on the Avaya Aura
Communication Manager system.
You can also administer the telephone to avoid unnamed registration and remain unregistered if
no extension and password are provided. For more information, see UNNAMEDSTAT in
Table8.
For more information about the installation process, see the Avaya 1600 Series IP Deskphones
Installation and Maintenance Guide.
