conference between the participants. When any participant leaves the call, the remaining participants may
experience a brief interruption as the system sets up a point-to-point call.
If one participant presses the call divert softkey/button during the barged call, the system plays the outgoing
greeting for the participant that pressed the softkey/button, and all participants can hear the greeting.
Call Back
Call back provides users with an audio and visual alert on the phone when a busy or unavailable party becomes
available. Call back works only with extensions that are in the dial plan. To receive call-back notification, the
user must press the call back softkey/button while receiving a busy, ringback, or reorder tone on the phone.
Call back is available automatically with Cisco Business Edition 3000, so you do not need to perform any
configuration tasks to use it.
Note
Call back only supports spaces and digits 0 through 9 for the name or number of the calling or called party.
To work with call back, the name or number of the calling or called party cannot contain # or * (pound sign
or asterisk).
If the phone of the calling party (User A) gets reset after call back has been enabled by the user, then call back
gets automatically cancelled. User A does not receive an audio alert, and the call back notification does not
display on the phone. If the phone of the called party (User B) gets reset, call back does not get cancelled.
User A will receive an audio alert, and the call back notification displays after User B becomes available.
When a Cisco Extension Mobility user logs in or logs out of a Cisco Extension Mobility-enabled phone, any
active call completion that is associated with call back automatically gets canceled.
If the user forwards all calls to voicemail, the user cannot use call back.
Example: User A calls User B, who is not available
User A calls User B. Because User B is busy or does not reply, User A activates the Call Back feature by
using the call back softkey or button. After User B becomes available (phone becomes on hook after busy or
completes an off-hook and on-hook cycle from idle), User A receives an audio alert, and call back notification
displays on the phone. User A goes off hook and dials the extension of User B. User B answers the call. Users
A and B go on hook.
Example: User A activates the Call Back feature for User B but is busy when User B becomes available
User A calls User B. User B does not answer. User A activates the Call Back feature by using the call back
softkey or button. User C then calls User A, and users A and C go on hook in an active call. User B becomes
available (phone becomes on hook after busy or completes an off-hook and on-hook cycle from idle) while
User A is still on an active call. User A receives an audio alert, callback notification displays on the phone.
User A can interrupt the active call to contact User B in either of the following ways:
• Dial from the call back notification screen. The active call automatically gets put on hold while User A
calls User B.
• Exit the call back notification screen and then park (or otherwise handle) the active call. After the active
call is handled, User A can press the CallBack softkey and select Dial to call User B).
Example: User A calls User B, who configured Call Forward No Answer to User C before call-back
activation occurs
