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 (104, 128), the dialed digits of the terminating number is verified against the terminating number screening database (108, 118). If the sequence of dialed digits is found in the terminating number screening database, the call is denied (112, 122). 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 (124). If the sequence of dialed digits is not found in the terminating number screening database, the call is allowed to process without interruption (110, 120). 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.
L'invention porte sur le filtrage des num~ros de destination pour empÚcher les moyens portatifs de paiement d'obtenir des communications avec des num~ros de destination domestiques ou internationaux r~put~s frauduleux. Lorsque la communication ~ ~tablir doit Útre factur~e ~ un moyen portatif de paiement (104, 128), le num~ro de destination est compar~ aux num~ros de destination de la base de donn~es de filtrage (108, 118). Si le num~ro appel~ se trouve dans ladite base de donn~es, la communication est refus~e (112, 122); on informe alors l'appelant de l'impossibilit~ d'~tablir une communication avec la destination appel~e et on lui demande s'il souhaite appeler un autre num~ro. Si le num~ro appel~ ne se trouve pas dans la base de donn~es de filtrage de num~ros de destination, la communication passe sans interruption (110, 120). Le but de cette fonction est de prot~ger le r~seau du service t~l~phonique contre des appels frauduleux r~p~t~s ~ destination de num~ros individuels de lignes domestiques ou internationales.
