Francois pointed out this draft was wrong to me a long time ago -
Nagendra and I agree with him. We just had not got around to fixing it.

VIA already supports SCTP, TLS-SCTP. And the draft provides the
references to RFC 4168 that defines it.
We've had this conversation before.
That is all well and fine for Vias (responses), but what
about requests triggered by a R-URI?
DTLS is defined in
http://tools.ietf.org/wg/sip/draft-jennings-sip-dtls-03.txt.
dtls-03 says that a SIP URI to be sent over DTLS should look
like the following:
sip:[EMAIL PROTECTED];transport=dtls-udp
Two questions:
1/ should it not be "sips" scheme here?
2/ If we are endorsing "transport=dtls-udp" in a SIP URI, then
saying that you should not put "transport=tls" in a SIP URI
seems silly. (Note that I personally do not like how
implementations have continued to use "transport=tls"
despite rfc3261 deprecating this. But questions will arise
in the future that why are we allowing "transport=dtls-udp"
and not "transport=tls"?)
Thanks,
