Abstract

In cases when a called participant is not registered on a packet oriented network, a call-back request made by a calling subscriber is transmitted automatically to a substitutional device which is disposed in a network and assigned to the called subscriber. Preferably, the callback request is stored in a separate database. As soon as the called subscriber is registered in the network, the callback request is transmitted to the called subscriber.
