  "abstract": "This specification defines a new Session Description Protocol (SDP) Grouping Framework extension called 'BUNDLE'. The extension can be used with the SDP offer/answer mechanism to negotiate the usage of a single transport (5-tuple) for sending and receiving media described by multiple SDP media descriptions (\"m=\" sections). Such transport is referred to as a \"BUNDLE transport\", and the media is referred to as \"bundled media\". The \"m=\" sections that use the BUNDLE transport form a BUNDLE group.\n\n This specification defines a new RTP Control Protocol (RTCP) Source Description (SDES) item and a new RTP header extension.\n\n This specification updates RFCs 3264, 5888, and 7941.\n\n This specification obsoletes RFC 8843.",
