Hi all. I'm using csipsimple with MY_USE_TLS=1 I installed an asterisk server and I configured it to allow TLS signaling and SRTP. I have also generated on Asterisk and copied on the client the three files (ca, .crt and .key) that are required in the settings. I can call the internal number "600" that is the "echo". I see tls of sip packets and I see UDP instead of the RTP packets. The problem is with one client calling another client (both of them correctly registered and able to make a secure call to 600). On asterisk I see the following error: == Problem setting up ssl connection: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure and there is no call between the clients. Any idea? Thank-you
