Hi Muthu

I have following comments
1. RFC 4856 defines "annexa" and "annexb" as optional parameters. So I agree there could be misinpterpretations.
2. The proposed draft should make these parameters as mandatory, otherwise the implementations would continue to ignore the parameters.
3. Update RFC 4856 moving "annexa" and "annexb" parameters from "optional" to "required".

Regards
Ranjit

A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Multiparty Multimedia Session Control Working Group of the IETF.

	Title           : Offer/Answer Considerations for G723 Annex A and G729 Annex B
	Author(s)       : Muthu Arul Mozhi Perumal
                          Parthasarathi Ravindran
	Filename        : draft-ietf-mmusic-sdp-g723-g729-04.txt
	Pages           : 8
	Date            : 2013-07-14

Abstract:
   RFC4856 describes the annexa parameter for G723 and the annexb
   parameter for G729, G729D and G729E. However, the specification does
   not describe the offerer and answerer behavior when the value of the
   annexa or annexb parameter does not match in the Session Description
   protocol(SDP) offer and answer.  This document provides the offer/
   answer considerations for these parameters and updates RFC4856.
