Unnamed Registration

As of Release 2.4, 4600 Series IP Telephones support unnamed registration. A telephone can register with the call server and receive limited service without requiring an extension and password entry. Unless otherwise disabled, the telephone automatically attempts to register unnamed if no action is taken on the telephone’s Extension entry screen. Administrators can disable unnamed registration by appropriately administering the system parameter UNNAMEDSTAT, as indicated in Table 7:  4600 Series IP Telephone Customizable System Parameters.

A telephone registered without the extension and password has the following characteristics:

• only one call appearance, preventing conferences or call transfers,
• no administrable feature buttons,
• on-hook dialing cannot be invoked,
• limited to the calling capability administered for PSA (Personal Station Access) on the call server, for example, only outgoing calls permitted subject to call server Class of Restriction/Class of Service limitations, and
• can be converted to normal, named registration by a valid extension and password entry.

Alternately, you can administer the telephone to avoid unnamed registration and remain unregistered if no extension and password are provided. For more information, see the UNNAMEDSTAT parameter in Table 7:  4600 Series IP Telephone Customizable System Parameters.
