IP-based multimedia communication systems, such as Session Initiation Protocol (SIP) [RFC3261] and [H.323], have the concept of a "call identifier" that is globally unique. The identifier is intended to represent an end-to-end communication session from the originating device to the terminating device. Such an identifier is useful for troubleshooting, session tracking, and so forth.

                   End-to-End Session Identification in                IP-Based Multimedia Communication Networks


   This document describes an end-to-end session identifier for use in    IP-based multimedia communication systems that enables endpoints,    intermediary devices, and management systems to identify a session    end-to-end, associate multiple endpoints with a given multipoint    conference, track communication sessions when they are redirected,    and associate one or more media flows with a given communication    session.  While the identifier is intended to work across multiple    protocols, this document describes its usage in the Session    Initiation Protocol (SIP).

   This document also describes a backwards-compatibility mechanism for    an existing session identifier implementation (RFC 7329) that is    sufficiently different from the procedures defined in this document.

   This document obsoletes RFC 7329.
