Vijay,
A very thorough review. I have one comment on it, below.
Thanks,
Paul

Hi:
The following is a review of draft-ietf-speechsc-mrcpv2-15 with
emphasis on S1-S5, S12 and S14. There are a few general comments
first; the rest of the comments follow in linear fashion with respect
to the sections enumerated above.

4. In SIP, when a server responds with an affirmative response,
it always adds a tag parameter to the From header.
Don't you mean To: header?
The initial INVITE should have a From-tag and the response should
contain that and a To-tag. All subsequent requests and responses in the
dialog should have both.
In the call
flow on page 16, the From header of the 200 OK does not contain
a tag parameter, it must. Interestingly enough, the subsequent
ACK request contains the tag in the From parameter (as indeed it
should.) Please add a tag parameter to the From header in the
200 OK, and ensure that it matches the one in the ACK request.
The tags are maintained for the duration of the lifetime of that
dialog.
Thus, in the re-INV that starts at the bottom of page 16, the
From tag must be maintained.
