Abstract
A method and device for preventing fraud in collect calls from a domestic origin point to an international terminating point through a long-distance telecommunications system is described. In the system and method, a Screening for International Calls database is added to the call processing platform. This Screening of International Calls database contains records keyed by country codes, and each record has a blocked collect call field listing destination numbers that are blocked from receiving collect calls. When a domestic-to-international collect call is made, the record corresponding to the country code of the international terminating point of the collect call is retrieved from the Screening for International Calls database. This record is checked to determine if the destination number of the collect call matches any destination numbers listed in the blocked collect call field of the country code database record. If there is a match, the call is blocked.
