Multi-business communication system and method thereof

PURPOSE: A multi-business communication system and a method thereof are provided to extend the script to interact with PSTN and IP telephones within the context of the same services, and share same service logic for both PSTN and IP media. CONSTITUTION: The scalable PSTN gateway(104,113,123,125) is a gateway that connects calls from a PC-based H.323 client application(102,115) to the regular PSTN telephone system(105,112,122,126). Inbound calls originating from the PSTN are connected through an IP connection(103,114,124) to a PC client application(102,115). Outbound calls originating from a PC client application are sent through the gateway to the PSTN destination. In addition, as illustrated, Voice Over Data(VOD) may provide an optional RISC-based solution for routing PSTN calls over a data network, allowing three types of voice connections PC-to-phone(100); phone-to-PC(110); and/or 3 phone-to-phone(120).
