Duplicate a SIP session
Paulo Loureiro, Pierre Imai, Bernd Lamparter · 2007
Session duplication copies media of an ongoing communication session from one device to another. After duplication the two devices have independent control over this media. This is in particular useful for one-way media like broadcast IPTV or Video-on-Demand. This document describes the general methods and specifies the signaling and media flows for providing this service using the Session Initiation Protocol (SIP).
