Hello Daniel, We have working prototype phone app for various mobile platforms (e.g. Android, iPhone, etc). We're likely going to release sometime this summer, but would be interested in betas, etc. fyi, we should work fine with a Kamailio + Asterisk configuration, but we haven't tested that configuration yet.
Our DTLS code leverages our TLS code. There shouldn't be much of a performance delta for crypto algo line rate, since both protocols (1.2) at that point are essentially the same. i.e. Both use an explicit IV, etc. We have some real world TLS performance metrics for a low-end PowerQuicc III processor on our website; http://www.mocana.com/benchmarks.html. I would imagine DTLS would be faster due to less memory copies per packet, than TLS over TCP/IP (more complex header, RTT, etc). Do you have a link to the Kamailio & SER meeting? It might be something we would be interested in participating in.

At the latest Kamailio & SER developer meeting, DTLS was put on the agenda for next major release (for the current release we added asynchronous TLS support), but the interest decreased as we couldn't find client DTLS implementations. Btw, as you aready did some work with DTLS, have you compared somehow DTLS vs TLS performances? Thanks, Daniel > TLS and DTLS implementations support 1.2 and lower, plus ~60 cipher > suites.
