Patent

CA 2071023

The present invention can provide an automatic busy message sending system for use in telephone communication to inform the calling subscriber, when the called subscriber's line is busy, of the duration of the busy status by voice. As the calling subscriber can receive, when the called subscriber's line is busy, a busy status message corresponding to the duration of the called subscriber's busy status instead of a busy tone, the calling subscriber can more accurately anticipate the ending time of the called subscriber's communication, and thereby minimize the repetition of the call initiating procedure. Since this service can be realized without having to add any particular extra equipment to the electronic switching system currently in operation, it can be offered free of additional charge and therefore expected to readily find extensive use.
