  • Patent number: 6044143
    Abstract: A method for transmitting calls between interconnected PBX systems within a private telephone network is disclosed. An initial call connection request is generated at an originating PBX system to a destination PBX system. The call connection request includes an indication of a specific destination number which may answer a call to the exclusion of any other destination number. If the specific destination number may not answer the call, the originating PBX system is notified of the call connection failure and the originating PBX accesses a pre-generated listing of alternate call destinations. Call connection then proceeds to one of the alternate destinations.
