Phone Features
Call Select
The Select softkey allows a user to select a call for feature activation, or to lock
the call from other devices that share the same line appearance. Pressing the
Select softkey on a selected call deselects the call.
When the call gets selected by a device, it gets put in the Remote-In-Use state on
all other devices that share the line appearance. No call in the Remote-In-Use state
can be selected. In other words, selecting a call instance will lock it from other
devices that share the same line appearance.
Selected calls are identified by a special display symbol.
Call Waiting
Call waiting lets users receive a second incoming call on the same line without
disconnecting the first call. When the second call arrives, the user receives a brief
call waiting indicator tone, which is configured with the Ring Setting (Phone
Active) in the Directory Number Configuration window.
Configure call waiting in the Directory Number Configuration window in
Cisco CallManager Administration by setting the busy trigger (greater than 2) and
maximum number of calls.
To configure call waiting for phones with no display (such as the
Tip
Cisco IP Phone Model 30 VIP) set the busy trigger to 2 and the maximum number
of calls to 2.
Conference List
The conference list feature provides a list of participant directory numbers that are
in an ad hoc conference. The name of the participant displays if it is configured
in Cisco CallManager Administration.
Any participant can invoke the conference list feature on the phone and can view
the participants. The conference controller can invoke the conference list feature
and can view and remove any participant in the conference by using the Remove
softkey.
