ABSTRACT:
A communication network element determines a service provider's routing preference for routing communications and routes these communications from an originating connection address to a destination connection address over a network. The communication network element includes a receiver configured to receive a signal, which comprises the originating connection address and the destination connection address. The communication network element also includes a processor that determines the service provider associated with at least one of the originating connection address and the destination connection address of the received signal. The processor also determines the routing preference associated with the service provider using routing data.
