<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Looping usually means, that Kamailio fails to detect that the message is<br>
target to itself. This is often caused by if the SIP domain in the<br>
request URI is not know to Kamailio's aliases.<br>
<br>
If you can not fix it, enable debug=3 and watch how the message is<br>
processed through the script to find out where the message is routed<br>
falsely.<br>
<br>
<br>
