The invention includes an originating switch for completing a call between the originating switch and a destination switch, the originating switch including structure for storing a ported number list or routing cache, structure for searching the ported number list or routing cache, and structure for routing a call to the destination switch. The invention also includes an adjunct processor for completing a call between the originating switch and a destination switch, the adjunct processor including structure for storing a ported number list or routing cache, structure for searching the ported number list or routing cache, and structure for providing the originating switch with a route for routing a call to the destination switch.
