Abstract:
A privacy screening service in an advanced intelligent network having a service control point and a service switching point in communication with a service node, comprising a first service package application on service control point and a second service package application on the service node, wherein:the first service package application re-directs a telephone call from a caller to a subscriber's telephone number to the service node; the second service package application at the service node sends a data request comprising the subscriber's telephone number to the first service package application at the service control point; the first service package application responds to the data request by retrieving a bypass code corresponding to the subscriber's telephone number, and sending that bypass code to the second service package application; the second service package application compares the bypass code received from the first service package application to a bypass code entered by the caller and, if the two bypass codes match, the second service package application dials a string of digits starting with a customized dialing plan code that triggers a query to the first service package application; and the first service package application returns a response with a lead number for the service node as the charge number, and the call is routed to the subscriber's telephone number.
