Look at the sip traffic flowing though server (e.g., with ngrep on
port 5060) and see where the packets are routed.<br>

<div>I used a stateless proxy and was able to
register. Now I am able to make calls as well but
there is an issue.</div>
<div><br>
</div>
<div>I receive multiple ringing but not receiving 200
ok after that. I keep on receiving the ringing
messages. Although the call gets connected and I
hear two way voice as well.</div>
<div><br>
</div>
<div>Also I am call through the sip number, but its
not receiving any calls.</div>
<div><br>
</div>
<div>Any ideas?</div>

</span>If it is the best is up to the experts,
but a way to do is to check wheter the<br>
source is the SBC or not. If the message is
from the SBC just handle it<br>
statefully (t_relay), if it isn't from the SBC
set the requested domain to the<br>
ipaddr of the SBC (10.1.2.3) and process
stateful. You could use the received<br>
port instead if external clients only
communicate on the special port<br>
($Rp!=6334)<br>
<br>
kamailio.cfg:<br>
<br>
#...<br>
port=5060<br>
port=6334<br>
#...<br>
<br>
request_route {<br>
#...<br>
<br>
if($si!="10.1.2.3")<br>
{<br>
$rd="10.1.2.3";<br>
}<br>
<br>
route(RELAY);<br>
