The draft-ietf-mmusic-sdp-g723-g729-04.txt related minutes of IETF84 is
given below for your reference:

"draft-muthu-mmusic-offer-answer-g723-g729-00.txt - Parthasarathi Ravindran

Hadriel had clarifying questions on the proposed solution.

Christer asked why this isn’t addressed by change to the document that
defined this payload (RFC 4856), to include the o/a considerations. IOW do a
bis of that document. Cullen said this should either be an update or a bis
to the original doc – it should not be a BCP.

Jonathan agreed with doing a bis. Roni said that when discussed in PAYLOAD
WG (with many of same people) they suggested bringing it to MMUSIC and doing
as BCP. Robert said BCP is almost certainly wrong. 

Chairs noted that nobody disagrees there is an issue. Chairs will discuss
with PAYLOAD WG chairs and ADs about what the proper process should be for
resolving and documenting it."

The related link is
http://www.ietf.org/proceedings/84/minutes/minutes-84-mmusic. The draft is
submitted as "Standards track" as per WG chairs & AD instructions after the
meeting and the relevant link is
http://www.ietf.org/mail-archive/web/mmusic/current/msg09590.html. 

Your other comments are related to RFC 4856 and I have initiated in the mail
thread to discuss those comments separately.

Thanks
Partha
