Abstract:
A system for detecting fraudulent calling card calls placed from an originating international location to a domestic termination, said system comprising:switch device for receiving a calling card call placed from an originating international location and capable of routing said call to a desired domestic termination; a device for automatically comparing a country code associated with said originating location and the desired domestic 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; and, a device for terminating said calling card call when said billing information is not verified, wherein subsequent calling card call attempts from originating international locations will result in default routing of said call to a first level operator for billing account information verification corresponding to said calling card, said calling card call being enabled for processing upon successful verification of billing account information, and terminated otherwise.
