Abstract

PURPOSE: To eliminate the necessity of useless time for both of a caller and a responder and to remove the troublesome and complicated events by setting up call originating ID in each event, registering plural incoming terminals correspondingly to the ID and allowing a call to come into the terminals in the order specified by the caller. CONSTITUTION: A call originating terminal sets up a call originating ID in each event through an ID-sorted group registering processing part 111 in an electronic exchange 100 and registers plural incoming terminals correspondingly to the ID. When an ID dialing specific number and the call originating ID are dialed from the call originating terminal at the time of dialing, an ID-sorted incoming processing part 112 in the exchange 100 executes call originating processing to the terminals registered correspondingly to the ID. An ID-sorted incoming processing part 114 executes incoming processing to a 1st order terminal registered correspondingly to the ID, and when the arrival of a call at the terminal is impossible, incoming processing to the succeeing order terminal is executed. Since incoming system sevice provided from the exchange 100 is stopped by an incoming service regulating processing part 113, the call is allowed to reach only the specified terminal.
