Integrated Services Digital Network User Part to Session Initiation Protocol Mapping
RFC 3398, “Integrated Services Digital Network User Part to Session Initiation Protocol Mapping”, is a Proposed Standard document published in December 2002 by G. Camarillo, A. B. Roach, J. Peterson, L. Ong. The canonical text is published by the RFC Editor.
Abstract
This document describes a way to perform the mapping between two signaling protocols: the Session Initiation Protocol (SIP) and the ISDN User Part (ISUP) of SS7. 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).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
