P. Jones: AUTHOR [+3]
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.
