Installing the Deskphone
in the first example will just wait for an extension and password entry and the telephone in the
second example will continue attempting to register at regular intervals. The downside of a
telephone being unregistered is that no one can use the telephone, for example, to report a
building emergency like a fire.
Unnamed registration allows the telephone to register without an extension and password.
Because there is no extension, telephony functionality is limited, specifically:
• The user has only one call appearance, and hence, cannot transfer or conference calls.
• The user has no administered feature buttons, and cannot invoke on-hook dialing.
• Extension-based information, like a given user's Contacts data or Option settings are not
available.
• The user is limited to the calling capability administered for PSA (Personal Station Access)
on the call server, for example, access to an emergency number.
• The telephone cannot receive any outside calls.
Unless otherwise disabled, the telephone automatically attempts to register unnamed if no
action is taken on the telephone Extension entry screen within 60 seconds. Initiating any ID or
password entry disables and prevents unnamed registration from occurring. Unnamed
registration is ignored after any dialpad entry.
Administrators can disable unnamed registration by appropriately administering the system
parameter UNNAMEDSTAT, as indicated in Chapter 7 of the Avaya one-X™ Deskphone H.323
Administrator Guide. Unnamed registration appears to the end user like Communication
Manager TTI Mode, and is similar from an administration perspective. For more information
about TTI, see your Communication Manager documentation.
