ABSTRACT:
A system is described for providing a single telephone number for geographically dispersed telephony service subscribers. The system includes an automatic call distributor (ACD) coupled to receive incoming calls from a public switched telephone network (PSTN) and a plurality of gateways coupled between the ACD and the Internet. Each one of the gateways is assigned to service a defined group of subscribers. The ACD selectively interconnects an incoming telephone call from the PSTN to an appropriate one of the gateways based on at least a portion of a setup message field identifying a telephone number forwarding the incoming telephone call.
