<p class=MsoNormal style='margin-bottom:12.0pt'>Hello,<br>
<br>
OPTIONS is not the request for initiating the calls, that is INVITE. You would
need to know SIP a bit in order to be able to understand and configure
Kamailio.<br>
<br>
If you don't see any INVITE on kamailo server via ngrep when you call, then the
issue is on client side or there is a firewall dropping it.<br>
<br>
Cheers,<br>
