Abstract
The invention concerns a method for establishing a telecommunication connection between a calling subscriber () and a target subscriber (), in which a calling terminal (R) of the calling subscriber () and a target terminal (Z) of the target subscriber () are assigned to a switching unit () and the calling subscriber () enters a callback request (CCBS-REQ, CCNR-REQ) in the switching unit () if the target terminal (Z) is busy or cannot be reached when a first call is made from the calling terminal (R) to the target terminal (Z), in which configuration data regarding the accessibility of the target subscriber () for a callback are entered into the switching unit (). Then the time is set for the switching unit () to make the pending callback (RC) to the calling subscriber () in order to generate a second call to the target subscriber () by processing the configuration data concerning the accessibility of the target subscriber () for a callback, at a time when the target subscriber () is reachable for a callback. Next, the switching unit () makes the pending callback (RC) to the calling subscriber () at the set time.
