Greetings. I'm unable to setup TLS and SRTP. I have a valid certificate from GlobalSign and my setup is currently the following: My certificate and key (merged with cat keyfile certfile > agent.pem) in /opt/freeswitch/conf/ssl/agent.pem The GlobalSign root certificate is in /opt/freeswitch/conf/ssl/cafile.pem I edited vars.xml as instructed from http://wiki.freeswitch.org/wiki/SIP_TLS#Configuration I tried running with tlsv1 and sslv23 in vars.xml, verified that FS is listening on ports 5061 and 5081 with netstat -nltp | grep freeswitch Also I get TLS listeners with "sofia status" so it should be working. Connecting to ports 5061 and 5081 with openssl s_client connect freeswitch.lan:<port> is successful, but I get a 'Verify return code: 21 (unable to verify the first certificate)'. Running nginx with the agent.pem as a certificate is working without any issues. When I try to connect to Freeswitch via TLS with Bria and Linphone 3.6.1 I get errors 408 or 503 and I don't see any output into the freeswitch console where I enabled sofia siptrace globally. What is the correct way to setup Freeswitch with a commercial certificate in order to enable TLS and SRTP ? Thank you!
