Avaya 1603 Guida Utente

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:

Unnamed Registration requires administration on the Avaya 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 

 in 

For more information about the installation process, see the Avaya one-X™ Deskphone Value 
Edition 1600 IP Telephone Installation and Maintenance Guide.

Assuming proper administration, most of the problems reported by telephone users are likely to 
be LAN-based. Quality of Service, server administration, and other issues can impact user 
perception of IP telephone performance.
