SIP, with certain extensions, facilitates the exchange of signaling information between an Originating MGC and a Terminating MGC to complete calls. This document describes the best current practice for using SIP to perform this function. Where possible this draft references necessary documents, and details the concepts and methods of encapsulating PSTN signaling information in SIP messages.}, }
