Hi!
I've just read the pjsip news - there is now also TLS support. You can use the included command line client for testing:
Merry Christmas and happy new year for all. I just checked in experimental TLS support in pjsip, just in case anyone is interested.
pjsua manual also has been updated: http://www.pjsip.org/pjsua.htm
I've also updated the getting started page with the instructions on how to enable TLS support during build. You can find it here: http://www.pjsip.org/using.htm
cheers, -benny
