ABSTRACT:
An approach for processing a call over a telecommunications system is disclosed. A call processor (e.g., a Service Control Point (SCP)) communicates with a switch to provide an alternative route for a call, received by the switch, that is determined to be a local portability number (LNP). A database coupled to the call processor stores the alternative routes associated with the LNP call; at least one of the alternative routes specifies a route that bypasses a local exchange network capable of terminating the call, whereby local access charges are avoided.
