Abstract

Subscriber calls in a communications network (10) are handled in accordance with the subscriber's routing plan for either originating and/or terminating calls irrespective of the manner in which such calls originate and terminate. Upon receipt of a call, a query is launched to a database (36) to obtain a called party routing number for the call destination in accordance with the subscriber's routing plan. Once the called party's routing number is obtained in response to the query, the called party's routing number is mapped a to physical port in the network when the routing number corresponds to a circuit-switched call destination or to an IP address when the called party's routing number corresponds to a packet-based call destination. The call is routed to the call destination in accordance with the mapping.
