WG,

Here is my individual review of the draft.

1. The Abstract must not contain citations, see 3.1.B of the
ID-checklist: https://www.ietf.org/id-info/checklist.html Instead use
title or abbreveitaded title to make clear what is referred to.

2. Section 3 and 3.1:

I believe that this section would be clearer if it was presented as:


3.  Updates to RFC 3551

   The following text of [RFC3551] is hereby updated as set forth below
   in Section 3.1:

   Audio applications operating under this profile SHOULD, at a minimum,
   be able to send and/or receive payload types 0 (PCMU) and 5 (DVI4).
   This allows interoperability without format negotiation and ensures
   successful negotiation with a conference control protocol.


3.1.  Updates to Section 6

   In the final paragraph of Section 6, replace, "payload types 0 (PCMU)
   and 5 (DVI4)," with "payload type 0 (PCMU)."  Also, add a final
   sentence to this paragraph that states, "Some environments MAY make
   support for PCMU mandatory." Resulting in the following paragraph:

   Audio applications operating under this profile SHOULD, at a minimum,
   be able to send and/or receive payload type 0 (PCMU). This allows
   interoperability without format negotiation and ensures successful
   negotiation with a conference control protocol. Some environments
   MAY make support for PCMU mandatory.

---- end of suggested text ----

Note, this does not take the other comments or mailing list discussion
into account.


Cheers

Magnus
