Call Appearance Keys
Normally, the first page of the main call handling screen contains three keys set as 'call appearance'
keys. These are allocated to you by your system administrator and are indicated as a=, b= and c=. An
underscored call appearance key (e.g. a=) indicates that the line is active.
Your system administrator can allocate a call appearance key with:

A Bridged Appearance
A bridged appearance key matches the status and operation of the call appearance key on a pre-
defined colleague
’
s phone. Hence, you can pick-up, make and receive calls on behalf of your
colleague.

A Line Appearance
An IP Office exchange line (but not IP lines) can be allocated to you such that the status of that
line is displayed and you can use the line appearance key to make and receive calls.

Call Coverage Appearance
A call coverage appearance key alerts you when a pre-defined colleague is receiving a call. The
covered user does not need to be using call appearance keys. Hence, you can pick-up calls on
behalf of your colleague.
For details of Bridged, Line and Call Coverage Appearance keys set-up and their operation, refer the IP
Office Key and Lamp Operation manual.
Having more than two call appearance keys is very useful. When holding a call, you can answer or make
another call and then switch between calls, transfer or conference. If you are set to receive call waiting
indication, the waiting call is shown against the next call appearance key.
Caution

Although the system administrator can replace the call appearance keys with Bridged, Line and
Call Coverage Appearance keys, this would severely restrict the use of features such as
conference and transfer.
It is for this reason that it is strongly recommended that all call appearance keys remain at
their default settings.
