Abstract:
A system for detecting fraudulent calling card calls, said system comprising:a switch device for receiving a calling card call placed from an originating international location and capable of routing said calling card call to an international termination; a device for automatically comparing a country code associated with said originating location and the international termination number against a database comprising combinations of country codes and termination numbers predefined as being high fraud risk; a device for routing the calling card call to a first level operator if a match against said database is found, said first level operator for verifying billing account information corresponding to said calling card; a device for terminating said calling card call when said billing information is not verified, wherein a subsequent calling card call from the originating international location will result in default routing of said subsequent calling card call to the first level operator, said calling card call being enabled for processing upon successful verification of billing account information, and terminated otherwise; and means for limiting the subsequent calling card call from the originating international location to a domestic location upon failure of verification of billing account information, said system further including device for routing said calling card call to a second level operator for verifying identity of the caller after a pre-determined number of calling card call attempts.
