I've found what was causing cdr to stop working. It's the mediator process failing to recognize call_type field.(Error inserting cdrs : Data truncated for column 'call_type' at row (sometimes 1 or 2 or 6))<br>
for calls originating from the asterisk server (prepended with fax- prefix for the moment). The mediator process dies instantly upon receiving such a record in kamailio table. I need to originate some calls from asterisk and i have used the fax server configuration logic for that. I see i will need to make a proper route for my calls from asterisk.<br>
<br>As for the nat detection i will make a trace calls and see what's going on.<br><br><br>Vladimir<br><br><br><br><div class="gmail_quote">On Mon, Jun 18, 2012 at 5:14 PM, Andreas Granig <span dir="ltr"><<a href="mailto:agranig@sipwise.com" target="_blank">agranig@sipwise.com</a>></span> wrote:<br>

Please ALWAYS reply to the list as well for others to see it (unless<br>
it's log messages we're requesting for in-depth trouble shooting).<br>

</div>Then rsyslog is not running on your machine, or there is some issue with<br>
your storage. Also make sure to use "zgrep" instead of "grep" when<br>
searching in /var/log/ngcp/old/, because the log files there are gzipped.<br>

</div>NAT detection is done based on the comparison of the source ip the<br>
request is coming from with the IP addresses in various header fields<br>
(e.g. Via and Contact). Do a tcpdump or ngrep to see the content of the<br>
SIP messages.<br>
