Hi Martin,
I have implemented DTLS inside my open source -and closed source- code years ago.
Obviously, not being used by anyone, this code is almost never tested. I can tell that it worked in labs years ago and I don't think it was ever used in production by any one that I know.
To test on a linux:
git clone https://git.savannah.gnu.org/git/osip.git cd osip ./autogen.sh ./configure make sudo make install cd ..
THEN:
git clone https://git.savannah.nongnu.org/git/exosip.git cd exosip ./autogen.sh ./configure make sudo make install
./tools/sip_reg -d -p 3456 -r sip:sip.antisip.com -u sip:xxxx@sip.antisip.com -U xxxxx -P yyyyy -t DTLS
I just fixed a crash upon failure... and pushed the change in git.
Anyway, feel free to test! I have only started the above "sip_reg" test without any proxy listening behind. Use your own kamailio and credentials!
And let me know the results ;) Aymeric

Hi, (repost in plaintext)
I haven't found anything that follows up on that expired draft, except in the sips: rfc5630 section 3.1.4 that appears to explicitly preclude UDP.
My issue is that a draft of BS8521part2 mandates TLS over UDP, and the closest I can see is sip-dtls over UDP but I'm struggling to find a clear declaration from within the sip community.
If I encounter an phone/app supporting it, I shall post it here.
