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,
Robert
