Abstract:
A method of communicating across a communication system comprising a circuit switched network and a packet switched network connected by a plurality of gateway objects, comprising the steps of:a) receiving in a directory object in said packet switched network a request for a gateway object address to establish a communication path between an identified requesting terminal and an identified destination terminal;b) communicating between said directory object and said gateway objects via interfaces between said directory object and said gateway objects to identify one of said gateway objects such that a communication through the one gateway object is capable of satisfying predetermined criteria;c) transmitting the address of the one gateway object to said requesting terminal;d) establishing a communication from the requesting terminal to the one gateway object at least partially through the packet switched network;e) launching a query from the one gateway object to an authorization object, in response to the communication from the requesting terminal;f) determining if communication between the requesting terminal and the destination terminal is authorized;g) if authorized, transmitting a response to the one gateway object indicating communication between the requesting terminal and the destination terminal is authorized; andh) initiating communication between the requesting terminal and the destination terminal through the one gateway object based on the response.
