Fig. 222 Callback to free user
Detailed Description
Tab. 274 Callback to free user
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.
