</div>Like Daniel already mentioned, add the header and msg_apply_changes()<br>
For example:<br>

</div>I decided to not use kamailio itself for sending these OPTIONS but to<br>
use a simple script that queries the database and simply opens a<br>
connection to the local kamailio. Mainly because I needed to monitor<br>
some UAC and alert when it wasn't reachable (even though it is present<br>
in location). In your case select the approriate UACs on Path.<br>
<br>
while($location=mysql_fetch_as<wbr>soc($res))<br>
{<br>
usleep(1000);<br>
$branch=uniqid();<br>
$send[$location['id']]=0;<br>
$dst=preg_replace('/.*@([^;]+)<wbr>;.*/',"$1",$location['path']);<br>
$dst=explode(':',$dst);<br>
if(count($dst)<2)<br>
{<br>
$dst[1]=5060;<br>
}<br>
$str=<<<EOS<br>
