Abstract
A method and apparatus using information stored in a communications switch to trace a specific communication in a network, including an in-progress communication. A search request with a set of search criteria is sent to a communications switch that routes communications in the network. Information stored in the communications switch, such as a communications switch call record, is searched to locate information matching the set of search criteria in the search request. The results of the search are reported out of the communications switch allowing the specific communication to be traced.
