SIP/SDP Over XMPP (SoX)
Peter Saint-Andre, Joe Hildebrand, Cullen Jennings · 2013
This specification defines an XMPP protocol extension for communicating Session Description Protocol (SDP) data, along with relevant Session Initiation Protocol (SIP) headers. The SoX protocol is designed for use by XMPP-only endpoints that need to communicate raw SDP information (e.g., in WebRTC scenarios), not as a general-purpose replacement for the XMPP Jingle extensions.
