Abstract:
A method and system for rating a packet based telephone call determines a source, and optionally a destination location of an Internet Protocol (IP) telephone call based on information contained within a call detail record. The locations are used to rate the call into any of a number of categories including local and long distance. In the case of hybrid calls which are packet based in part but which also traverse the Public Switched Telephone Network (PSTN), the method and system can identify the call as a gateway based call and rate the call appropriately.
