Automatic callback method for a packet-oriented network

摘要

In cases when a called participant (Tln-B) is not registered on a packet orientated network (IP-N), a call-back request made by a calling subscriber (Tln-A) is transmitted automatically to a substitutional device (ST-B) which is disposed in a network (IP-N) and assigned to the called subscriber (Tln-B). Preferably, the call-back request is stored in a separate data base (DB-B). As soon as the called subscriber (Tln-B) is registered in the network (IP-N), the call-back request is transmitted to the called subscriber (Tln-B) who carries out said request.
