Patent ID: 8401166

Claim:
A computing device for mitigating phantom call traffic in a communications system, the computing device coupled to a communications exchange and comprising: a processor; a memory; and a call routing application maintained in the memory and executed by the processor to mitigate phantom call traffic, the call routing application including computer-executable instructions for: importing a local calling area database into the computing device; receiving a call via an ingress trunk group in connection with the communications exchange, the call originating from an originating carrier and having corresponding ingress signaling information including a charge number, a calling number and a called number; determining a jurisdiction of the call in real-time based on the charge number, the called number and the local calling area database, the jurisdiction being one of local, intra-LATA or inter-LATA; determining an egress trunk group, the egress trunk group being one of a local egress trunk group or an access egress trunk group; determining egress signaling information based on the jurisdiction of the call; delivering the call and the egress signaling information from the communications exchange to a local exchange via the egress trunk group; and providing at least a portion of the egress signaling information for inclusion in a call detail record.
