Hello,
for Kamailio v4.3 you can print is syslog the $mb as it was suggested in the other response (https://lists.kamailio.org/pipermail/sr-users/2018-February/100378.html), you can do that in request_route or onreply_route. In onsend_route you can print $snd(buf).
Then there is siptrace module that can work standalone and store sip traffic in a database table.
If you have a production system with lot of traffic, Homer Sipcapture project might be something to consider -- kamailio has the modules siptrace and sipcapture.
I also want to highlight that v5.1 has a new module sipdump that should simplify the capture of sip traffic:
* https://www.kamailio.org/docs/modules/stable/modules/sipdump.html
I added it because I needed to look at tls traffic while developing/debugging.
Cheers,
Daniel
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-to-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?
Thank you in advance,
