    abstract =  {This document expands and clarifies the behavior of the Real-Time Transport Protocol (RTP) endpoints when they are sending multiple media streams in a single RTP session. In particular, issues involving Real-Time Transport Control Protocol (RTCP) messages are described. This document updates RFC 3550 in regards to handling of multiple SSRCs per endpoint in RTP sessions.},
