Abstract
A method is disclosed for monitoring call setup communications between a communications station and a telecommunications network. A plurality of so-called "result codes," each consisting of a numeric prefix and an associated textual message, are transmitted from the telecommunications network in response to an attempted call setup. These result codes are screened at the communications station by matching numeric prefixes against a predetermined list of selected numeric prefixes and to eliminate irrelevant and/or redundant messages. Next, an alphanumeric display is utilized at the communications station to display in a user discernible manner all those messages indicative of the status of call setup information.
