Hello,<br>
<br>
you can force rtp relaying always, if it is what you want -- just
call rtpproxy_manage() for all INVITE requests and their replies.<br>
<br>
Otherwise you have to tune the nat_uac_test() parameter in order to
match what you want to relay.<br>
<br>
For signaling relaying, be sure you do record_route() for calls.<br>
<br>
Cheers,<br>

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><br>
</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>
