I'm trying to register with TLS connection . I changed the transport type to TLS but failed to register . I have read about TLS handshake but I have no idea how to set it with liblinphone.
I tried to get a server certificate with command
openssl s_client -connect xxxxx.com:443 |tee logfile
and add it to rootca file in linphone project but it's not working . The free sip server that i tried is sip2sip.info
