ABSTRACT:
An advanced intelligent network telephone system for terminating calls to subscribers to a privacy screening service, when the calling party has a private telephone number. Privacy screening services allow a subscriber to manage and monitor incoming telephone calls, such that unwanted calls are not terminated to the subscriber. When a calling party dials the telephone number of a subscriber to a privacy screening service, the system manages the call according to whether the calling party number is known and public, known and private, or unknown. If the calling party number is known and public, the call is routed to the subscriber. If the calling party is known and private, the call is routed to a service node, which plays an announcement to the calling party, asking the calling party for permission to override his or her privacy. If the calling party agrees, the service node dials a customized dialing plan (CDP) code that triggers an info analyzed query from the service node's service switching point (SSP) to a service control point (SCP). If the calling party is unknown, the service node asks the calling party to record his or her name. If the calling party records his or her name, the service node dials a CDP code, that triggers an info analyzed query to the SCP.
