<p>Hello,</p>
<p>that error should appear when request_route {} block is not
found. It can be due to the fact that some #!ifdef are not
properly closed with #!endif, can you double check? If still not
fixed, set in your kamailio.cfg:</p>
<p>verbose_startup=1<br>
</p>
<p> debug=3</p>
<p>and then send the debug messages when kamailio is started.<br>
</p>
Cheers,<br>
Daniel<br>
