ABSTRACT:
Local/toll dynamic routing integration is achieved within a telecommunications network (14) that includes at least one dynamic routing local switching system (24-1) for receiving incoming call and a plurality of toll switching systems (27-1 through 27-7) at least one of which is associated with each local switching system. For each incoming call, the local switching system (24-1) derives a set of Class-Of-Service (COS) parameters indicative of the class-of service associated with the call. In accordance with the COS parameters, the local switching system (24-1) determines whether each incoming call is a featured call, requiring routing to the toll switching system associated therewith, or a non-featured call. Featured calls are routed to the toll switching system associated with the local switching system for feature processing, whereas non-featured calls are routed by the local switching system itself in accordance with the COS parameters, thus relieving the load on the associated toll switching system.
