Abstract
In a communication system comprising multiple networks, a system is provided for notifying a caller that a call destination who was initially unavailable is now available, involving subscribers of possibly different networks. The system, when installed in a network, can support destination availability notifications following failed call attempts in which at least one user is a user of the network, regardless to which network the other user subscribes.
