Abstract
A number of gateway objects interconnect circuit switched and packet switched networks, such as the telephone network and the Internet, for example to enable telephony communication across the combined networks. A directory object coupled to the packet network provides address translation capability, and the directory object polls or communicates with the gateways to provide an intelligent selection of one of the gateway objects, typically for egress to the telephone network. The system also includes an authorization control object. After gateway selection, a calling terminal attempts communication through the gateway object. The gateway object then queries the authorization control object, which instructs the gateway object to proceed only if the requested communication between the calling terminal and the destination terminal is authorized.
