ABSTRACT:
To facilitate the processing of an incoming telephone call associated with a respective telecommunications network service an initial address message identifying the incoming call is intercepted before the message is presented to an associated toll switch that will process the call. The intercepted message is then examined in order to identify the toll switch service logic that will process the call. The resulting identity is then appended to the message and that result is then passed to the toll switch so that the identified service logic may be invoked to process the call in accord with the requested service.
