<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
in a quick look at the trace and the code, the assignment with empty value seems to be the issue, likely to be:<br>
<br>
<span style="color:#1F497D">$rU = $dbr(ra=>[0,1]);</span><br>
<br>
I remember that a similar issue was fixed long time ago, but not sure before your version (3.2.x) which is very old right now. If you have time, you can simulate the same situation using a more recent version such as 4.2 or 4.3.<br>
<br>
Being traveling, I can't do much testing and analysis of the commit logs to see what and when was fixed.<br>
<br>
For the moment, you can try to catch the situation in the config:<br>
<br>
<span style="color:#1F497D">if($dbr(ra=>[0,1])!="") $rU = $dbr(ra=>[0,1]);</span><span style="font-size:12.0pt;mso-fareast-language:EN-ZA"><o:p></o:p></span></p>

<p class="MsoNormal">Cheers,<br>
Daniel<br>

according to the log, you got a coredump:<o:p></o:p></p>

Send the output of 'bt full' taken with gdb from the core file -- the core file is either in / or in the working dir of kamailio.<br>
<br>
Also, mention the version of kamailio that you are using (kamailio -V).<br>
