Hi Linda,

Thank You for the review!

I think Gunnar has already answered your question. I have nothing to add, but I send this reply to indicate that I have ready your review :)

Regards,

Christer

Subject: Genart last call review of draft-ietf-mmusic-t140-usage-data-channel-11

Reviewer: Linda Dunbar
Review result: Ready with Nits

I am the assigned Gen-ART reviewer for this draft. The General Area
Review Team (Gen-ART) reviews all IETF documents being processed
by the IESG for the IETF Chair.  Please treat these comments just
like any other last call comments.

For more information, please see the FAQ at

Document: draft-ietf-mmusic-t140-usage-data-channel-11
Reviewer: Linda Dunbar
Review Date: 2020-02-14
IETF LC End Date: 2020-02-06
IESG Telechat date: Not scheduled for a telechat

Summary:
 This document specifies how a WebRTC data channel can be used as a transport
 mechanism for T.140.  The document  ties several other documents together,
 like xxx can be used, yyy must  be followed, etc..  So it is not easy to
 validate the mechanism described by the document unless you are familiar with
 all the reference documents.
But in general, the document is very clear.

Just one question:
ITU-T T.140 uses RTP as transport, whereas this document describes using WebRTC
for transport.  WebRTC uses SRTP.

Does it mean this document proposes a different transport mechanism as the
ITU-T T140?  Why?

Major issues: None

Minor issues: None
