This document describes a Real-time Transport Protocol (RTP) payload
format for transporting comfort noise (CN).  The CN payload type is
primarily for use with audio codecs that do not support comfort noise
as part of the codec itself such as ITU-T Recommendations G.711,
G.726, G.727, G.728, and G.722.
