    abstract =  {This document describes an end-to-end Session Identifier for use in IP-based Multimedia Communication systems that enables endpoints, intermediate 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. This document also describes a backwards compatibility mechanism for an existing "in the wild" implementation that is both sufficiently different than the standard solution and whose implementation will likely not be updated ever by some vendors.},
