Everybody’s favourite SIP stack (reSIProcate) now has (preliminary) support for Datagram TLS (DLTS) [paper, draft]. What a coup! Big thanks to Nagendra for his contribution of time, labour and understanding. Nagendra is one of the authors of the IETF internet draft that outlines the DTLS protocol, co-authored with Eric Rescorla, of OpenSSL general fame.
Update: Ekr points out that he’s not really directly involved with OpenSSL, oops.
