This document describes the RTP payload format of a mU-law Embedded
Coder for Low-delay IP communication (UEMCLIP), an enhanced speech codec
of ITU-T G.711. The bitstream has a scalable structure with an embedded
u-law bitstream, also known as PCMU, thus providing a handy transcoding
operation between narrowband and wideband speech.
Working Group Summary
This is a reasonably standard RTP payload format. The document has been
reviewed by the AVT working group and all open issues were addressed
Media type review was conducted starting 26 February 2008, with no
objections raised. There is at least one implementation.
Roni Even is the document shepherd.
The responsible area director is Cullen Jennings.

Followings are additional guidelines for establishing a session using
an offer-answer model.
The following is a detailed list on the semantics of using
the UEMCLIP payload format in an offer-answer exchange:
In S1, second paragraph:
switched using SDP exchange.

In S2, first paragraph:
shift to the wideband.
shift to using wideband communication.
