    abstract =  {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.},
