RFC 6465 Mixer-to-Client Audio Level Indication December 2011 extension. RFC 3550 [] only allows RTP packets to carry a maximum of 15 CSRC IDs.Given that audio levels directly refer to CSRC IDs, implementations MUST NOT include more than 15 audio level values. The maximum value allowed in the len field is therefore 14 for the one-byte header format and 15 for the two …
