<p class=MsoNormal style='margin-bottom:12.0pt'>These are replies to INVITE
requests, but if you see them, the INVITE passed through the server as well.<br>
<br>
If you are not aware of a firewall, then perhaps you don't have one unless is a
default installation with it enabled or one on the network.<br>
<br>
I suggest you do sip tracing on the client machine to see if the invite
requests leave to the proper IP.<br>
<br>
Ultimately can be also a problem caused by a NAT router with ALG, if the client
is behind such device.<br>
<br>

<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>
