 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
