Abstract

   This document describes a way to map Integrated Services Digital
   Network User Part (ISUP) overlap signalling to Session Initiation
   Protocol (SIP).  This mechanism might be implemented when using SIP
   in an environment where part of the call involves interworking with
   the Public Switched Telephone Network (PSTN).
