The callback function allows you to leave a callback request for another subscriber. These callback requests are stored in the list "My Callback Requests" in the call journal.

In the list of callback requests you can use the standard functions of the call journal (10.7.2 Functions in the Call journal).

If another subscriber has left you a callback request, this is indicated in the caller list and/or under "Missed Calls". You will find further information concerning callback requests in 10.17 Callback request.
