Step 4: Telephone and the Call Server

The call server referred to in this step is the Avaya Media Server.

In this step, the telephone might prompt the user for an extension and password. The telephone uses that information to exchange a series of messages with the call server. For a new installation and for full service, the user can enter the telephone extension and the call server password. For a restart of an existing installation, this information is already stored on the telephone, but the user might have to confirm the information. The telephone and the call server exchange more messaging. The expected result is that the telephone is appropriately registered and call server data such as feature button assignments are downloaded.

The 9600 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 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.

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 Table 7.
