Hi, For a few days already I am trying to activate the TLS feature in PJSIP. My server is FreeSwitch and was compiled to support the TLS and SRTP. When I using closed source soft phones, the server does support it. However, when I try to use the pjsua (./pjproject/pjsip-apps/bin/pjsua-i686-pc-linux-gnu) i am observing a weird behavior. I am sniffing with wireshark and sees the the TLSv1 packets (Client Hello, Client Key Exchange, etc.) when the client logs in. However, when I try to make a call to another party, I see that the INVITE is sent as clear text, i.e. plain simple SIP.
