The RTP Control Protocol (RTCP) Canonical Name (CNAME) field is intended to provide a stable endpoint identifier for participants in an RTP session. The definition of the CNAME field in 3550 is known to be problematic in the presence of NAT devices, and there are privacy concerns around the use long-term persistent identifiers as RTCP CNAMES. This draft proposes updates to 3550 to address both concerns.
