ABSTRACT:
A system routes local toll-free calls dialed to a toll-free number via local switches and network onto interconnecting local providers with local access settlement rates, thereby allowing a local rather than toll cost structure. The system operates with existing a subscriber's existing toll-free service provider. When an originating number is identified as an LCA or intraLATA call, the system routes the local toll-free call from the SCP network to participating local switches that service the subscriber's terminating number. The originating calls are separated between the LCA and the rest of the LATA based upon the NPA-NXXs that are considered local to the subscriber's terminating number. The system also provides for routing local toll free calls and for reporting each local toll free call to the subscriber.
