ABSTRACT:
A method and apparatus for improving call connection to one of a plurality of destination numbers on a calling list is disclosed. The method involves monitoring the inband signals between an interrogating mobile switching center and a remote node during call setup procedures. An inband monitoring device looks for terminating signals indicating that call setup to the remote nodes will not be completed. Upon detection of such a termination signal, the call setup procedure is immediately discontinued without waiting for expiration of a call answer timeout period.
