Abstract
A method and device for preventing fraud in international calls in a long-distance telecommunications system, where selected customers can avoid fraud control blocks and greater granularity is achieved in blocking international destinations. In the method and device, an override flag is created in the records of the Billing Number Screening (BNS) database. When a call is made using a billing number whose corresponding record has the override flag set, the call is not stopped by fraud control blocks on certain international destinations. In addition, international destinations can be blocked with greater specificity because a Country Set Logic (CSET) field is added to the International City Code Database. The addition of CSET to this database allows particular international city destinations to be blocked from certain origin points.
