Installing the deskphone

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.

You can see the extension as you enter the extension, but the password is displayed
as stars (*). The system determines whether the extension is in use.
When this process is complete, you can hear a dial tone when you press the Phone
On-hook/Off-hook button. The dial tone indicates that the IP phone is installed
successfully.
