Systems and methods of mitigating phantom call traffic

摘要

Systems and methods for mitigating phantom call traffic in a communication system are disclosed. A call may be received at a communications exchange. A jurisdiction of the call may be determined in real-time, and egress signaling information and a route of the call to a terminating local exchange may be determined based on the jurisdiction. At least a portion of the egress signaling information may be provided to the terminating exchange in call signaling and/or in call detail billing records so that the terminating exchange is enabled to correctly charge for call termination.

主权项

1. A computing device for routing a call 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, the call routing application including computer-executable instructions for:
receiving a call via an ingress trunk group in connection with the communications exchange, the call originating from an originating carrier and having respective ingress signaling information including a charge number;determining a jurisdiction of the call in real-time based on the charge number and a local calling area database accessible to the computing device, the jurisdiction of the call corresponding to a relationship between the originating carrier and a carrier of a terminating end of the call;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; anddelivering the call and the egress signaling information from the communications exchange via the egress trunk group.
