Understanding Unnamed Registration; Pa System - Avaya B189 Installing And Maintaining

Understanding unnamed registration

In an IP phone, when you register with a call server, and receive limited service, without requiring an
extension and password entry, this functionality is called as Unnamed registration. Unnamed
registration is useful in the following environments:
• "Hot-desking" environments where a time gap exists between one user logging out and another
user logging in on the same deskphone.
• Road warrior mode of use where a traveller can run the telephony features and functionality by
taking over the office deskphone extension.
In both examples, the user unregisters the deskphone by logging off or by taking the office
deskphone extension over to another deskphone. Without unnamed registration, the deskphone in
the first example will wait for an extension and password entry and the deskphone in the second
example will continue attempting to register at regular intervals. The disadvantage of a unregistered
deskphone is that no one can use the deskphone, for example, to report a building emergency like a
fire.
In Unnamed registration, the deskphone registers 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.
• The user cannot reach extension-based information, such as the Contacts data of a given user
or Option settings.
• 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 deskphone cannot receive any outside calls.
Unless otherwise disabled, the deskphone automatically attempts to register unnamed if no action is
taken on the deskphone Extension entry screen within 60 seconds. To disable and prevent
unnamed registration, enter an ID or password. The system ignores unnamed registration after any
dialpad entry.
