Making calls – enhanced functions 43
Callback
If you cannot reach a subscriber, either because there is no response or the line
is busy, you can activate a callback.
If the subscriber has hung up or (if there is no answer) any other activity has
been detected on the subscriber's phone, you will receive a callback advisory
call. If you accept this call, an attempt will be made to reach the party again.
You can enable callbacks for multiple phone numbers at the same time and can
delete all active callbacks. Displaying and deleting individual callbacks is not
possible.
