Callback to free Subscriber
Subscriber A can activate a callback to subscriber B, if B does not answer A's call.
After subscriber B has made another call (gone off-hook and then back on-hook
again), subscriber A is called within 10 s. As soon as A picks up the phone, the
system automatically calls subscriber B.

Detailed Description

Inter- Operating sequence / signalling on the terminal Scope
face
A Once the callback procedure has been exe-
cuted, A obtains the acknowledgement tone.
B
The callback is triggered only to subscriber A, who set the callback, regardless of
whether a call diversion or call forwarding to a subscriber C has been activated at
A.
Amount of time a callback to free subscriber remains valid: 45 minutes.
If B has a system terminal with display, a text message with a callback prompt will
appear, i. e. the callback is not automatically initiated by the PBX. In principle call-
back requests are displayed with maximum priority on the terminal, i. e. before
notifications by the Voice Mail System and before any text messages.
