Hello,<br>
<br>
do you have rtpproxy or rtpengine for relaying rtp packets? Kamailio
is routing only sip packets, you need the rtp relay application to
help with media streams.<br>
<br>
Cheers,<br>

<div>Hello</div>

</div>
<div>I need a small guidance on creating a light weight proxy
which only forwards the msgs to my sip server and also does
supports symmetrical nated clients.</div>
<div><br>
</div>
<div>The way I have created the configuration is a slight
modification of :</div>

<div><br>
</div>
<div>Problem is unless the sip clients use STUN media packets are
not routed. And sometimes even the signalling does not pass
through.</div>
<div><br>
</div>
<div>Should i not use fix_nated_register and switch to fix _
nated_contact always ?</div>
<div><br>
</div>
<div>Because in all those cases where signalling does not pass
through, I see RTO. My best guess is kamailio trying to
communicate with private ip.</div>
<div><br>
</div>
<div>Anything which I can try that you could suggest from the top
of yourmind woyld be muc appreciated. </div>
