SUBSCRIBERLESS DIFFERENTIATED ROUTING SYSTEM AND METHOD

A differentiated routing system includes a computer-executable system to receive a request from a first network gateway of a native network for establishing a communication service from a calling party terminal to a called party terminal. Upon receipt of the request, the system determines that policy information is not known for the calling party terminal that has originated the request, and therefore append a tag to the request in which the tag indicates that the requested communication service is to be established using one or more generic policies. The generic policies include one or more default policies to be used for establishing the communication service. The system then transmits the request to a routing device, wherein the routing device determines how the communication service is routed through the native network according to the one or more generic policies.
