Abstract:
1. A privacy management system that permits a subscriber to screen calls made to the subscriber, comprising: a first service switching point connected to a subscriber telephone that receives a telephone call from a calling party that is intended for the subscriber and in response to the call initiates a query to determine whether the call is from a public telephone number, a private telephone number, or an unknown telephone number; a second service switching point connected to a service node and the first service switching point; and a service control point in communication with the first and second service switching points that receives the query and responds to the query; wherein when the telephone call is from a public number, the telephone call is forwarded directly to the subscriber, and optionally when the telephone call is from a private number or unknown number, the telephone call is directed to the service node through the second service switching point, wherein a presentation indicator is first toggled and afterwards the service node requests from the calling party whether calling party information may be forwarded to the subscriber before forwarding the telephone call to the subscriber, and if authorized provides that information from the service control point, wherein the system is configured for preserving and delivering the calling party number from a private calling party to the subscriber.
