UEMCLIP (mU-law EMbedded Coder for Low-delay IP communication) is μ-law-based voice codec. This codec is base of G.711.1 [1].
The RTP payload format document describes the data packets and chapter 4 explains the transcoding possibility between G.711 and UEMCLIP. It is mentioned here that sub layer index 0 is standard G.711 data, but this sub layer block might or might not follow immediately the headers (so the sub layer headers must be parsed).
