The changes in this version are as follows:

- In Section 4.3, clarify reference to draft-ietf-rtcweb-audio and add reference draft-ietf-rtcweb-video for mandatory to implement codec and payload formats. Clarify that other codecs and payload formats MAY be implemented, and that all payload formats MUST be signalled before use.

- In Section 5.2.5, note that the CVO header extension MUST be implemented as described in Section 4 of draft-ietf-rtcweb-video.

- In Section 4.1, note that the RTCP SDES MID item MUST be implemented if the SDP bundle extension is used. In Section 5.2.4, note that the RTP MID header extension MUST be implemented if the SDP bundle extension is used.

- In Sections 5.2.1, 5.2.2, and 5.2.3, clarify that the header extension needs to be negotiated before it can be used.

- In Section 5.2.2, clarify that the RFC 6464 client-to-mixer audio level header extension MUST be implemented, based on discussion in IETF91.

- Update Section 6.2 on FEC to refer to draft-uberti-rtcweb-fec.
