Abstract

A method and system for handling incoming calls when no destination stations are available. When an incoming call from an originating station is received, it is determined whether a destination station is available. If a destination station is not available, a telephone number of the originating station is stored, Shortly before its current call is concluded, a destination station indicates its approaching availability. Responsive to this indication, an outgoing call is placed to the originating station. If the originating station does not answer the outgoing call within a predetermined time, the outgoing call is terminated and rescheduled. If the originating station answers the call within a predetermined time, the outgoing call is connected to the available destination station.
