Abstract
A remote access call forwarding method and system adapted for an Advanced Intelligent Network to forward a call incoming to a subscriber's telephone number in response to a routing destination number if the routing destination number does not correspond to a blocked destination identifier retrieved from a database. Further, a search to a subscriber profile unique to each subscriber is provided, the subscriber profile containing valid routing destination numbers previously validated to which the calls incoming to the subscriber have previously been forwarded. Thus, calls are forwarded in response to the routing destination number when the routing destination number matches a valid destination number found in the subscriber profile.
