Abstract

A telephone call is made by a calling party. The telephone call is routed through a telephone network to a piece of terminal equipment. The terminal equipment analyzes call information associated with the telephone call. The call information is divided into separate call attributes, such as calling telephone number and called telephone number. One or more number lists, stored in the terminal equipment, are then searched to see if they contain an entry that matches the call attributes. If a match is not found, the call is rejected. If one or more matches is found, the call is routed as specified by the number list entry having the most optimal match. The number lists can be easily user-modified.
