Callback to free user

User A can activate a callback to user B if B does not answer A's call. Since user B is
making another call (gone off-hook and then back on-hook again), user A is called
within 10 s. As soon as A picks up the phone, the system automatically calls user B.

Detailed Description
Tab. 274 Callback to free user
Interface Operating sequence / signalling on the terminal Scope
A Once the function has been executed, A obtains
the acknowledgement tone.
B
The callback is triggered only to user A, who set the callback, regardless of whether
a CFU or CFNR to a user C has been activated at A.
Amount of time a callback to free user remains valid: 45 minutes.
If B has a system phone with display, a text message with a callback prompt will ap-
pear, i. e. the callback is not automatically initiated by the communication server. In
principle callback requests are displayed with maximum priority on the system
phone, i. e. before notifications by the voice mail system and before any text mes-
sages.
