Hello!
I'm working on setting up our kamailio instance to use TLS for inter-phone communication and so far I've been able to configure the GUI and get it to work which is great. However, I'm trying to grab a packet capture and decode the TLS session to get the SIP ladder (so I can troubleshoot issues) and so far I've been unable to. I've been following the article at: http://packetpushers.net/using-wireshark-t o-decode-ssltls-packets/ and using the kamailio self-signed cert as I think that's the cert being used with no success. I'm getting the Cipher Suite: TLS_RSA_WITH_AES_256_CBC_SHA (0x0035) which doesn't use perfect forward secrecy so it should be able to be decoded.
Is there a way to decode the kamailio TLS encoded communications so I can troubleshoot issues that may come up?
Robert,
You could dump the pseudo-var $mb using the corex module in the event_route[network:msg] hook. https://kamailio.org/docs/modules/4.3.x/modules/corex.html
