摘要： A system and method are provided for blocking a telephone call from a calling party to a called party, the calling party associated with a calling party directory number, including a local-designated trunk group over which the incoming telephone call from the calling party is received. A service switching point is coupled with the local-designated trunk group, the service switching point receiving the telephone call, generating a query message including the calling party directory number, and sending the query message to a service control point. The service control point is coupled with the service switching point, receives the query message, and determines if the calling party is inter Local Access and Transport Area (interLATA) with respect to the service switching point. Where the calling party is determined to be interLATA, the service control point determines a screening indicator value, and generates a response message to the service switching point to block the telephone call received via the local-designated trunk group where the screening indicator value indicates that the telephone call is public telecommunications network provided.
