ABSTRACT:
The present invention provides a method and apparatus for selectively restricting only forwarded calls. Upon realizing that an incoming call was incorrectly forwarded, the terminal receiving the incoming call transmits to a telecommunications exchange an indication requesting activation of a subscriber feature that will restrict only forwarded calls from the terminal forwarding the call. The directory number for the terminal forwarding the call is retrieved from a register. That retrieved directory number is correlated with the directory number representing the terminal incorrectly receiving the forwarded call and the correlated data is stored at a database. Upon the receipt of the next incoming call, the telecommunications exchange determines that the call is forwarded. Then, the directory number associated with the forwarding party is compared against the data previously correlated and stored in the database. If the directory number associated with the forwarding party matches the directory number stored in the database, the call is rejected.
