Abstract
Terminating number screening to block portable billing products from terminating to a designated high fraud domestic or international terminating numbers. When a call is placed and it is billed to a portable billing product, the dialed digits of the terminating number is verified against the terminating number screening database. If the sequence of dialed digits is found in the terminating number screening database, the call is denied. The caller is then informed that they cannot place a call to this destination and asked if there is another terminating number they wish to call. If the sequence of dialed digits is not found in the terminating number screening database, the call is allowed to process without interruption. The purpose of this functionality is to protect the Operator Service network from repeated fraudulent calling to individual telephone line numbers either international or domestic. The unique characteristic of this function is the ability to select a single terminating number for blocking, based on product type, such as a calling card, Credit card, and other billing options.
