<p>Hello,</p>
<p><br>
</p>
<p>for Kamailio v4.3 you can print is syslog the $mb as it was
suggested in the other response
(<a class="moz-txt-link-freetext" href="https://lists.kamailio.org/pipermail/sr-users/2018-February/100378.html">https://lists.kamailio.org/pipermail/sr-users/2018-February/100378.html</a>),
you can do that in request_route or onreply_route. In onsend_route
you can print $snd(buf).</p>
<p><br>
</p>
<p>Then there is siptrace module that can work standalone and store
sip traffic in a database table.</p>
<p><br>
</p>
<p>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.</p>
<p><br>
</p>
<p>I also want to highlight that v5.1 has a new module sipdump that
should simplify the capture of sip traffic:</p>

<p><br>
</p>
<p>I added it because I needed to look at tls traffic while
developing/debugging.</p>
<p><br>

<p>Cheers,<br>

<p style="margin-top:0;margin-bottom:0">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: <a
href="http://packetpushers.net/using-wireshark-to-decode-ssltls-packets/"
class="OWAAutoLink" id="LPlnk787507" previewremoved="true"
moz-do-not-send="true">http://packetpushers.net/using-wireshark-to-decode-ssltls-packets/</a> and
using the kamailio self-signed cert as I think that's the cert
being used with no success. I'm getting the
<span style="font-size: 12pt;">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.</span></p>

the kamailio TLS encoded communications so I can troubleshoot
