</div>I don't know why you insisit on it. Having symmetrics NAT is not a<br>
problem at all if you use RtpProxy, please don't insist more on it<br>
since this is not your problem.<br>
The only problem that symmetric NAT produces it the fact that<br>
symmetric NAT doesn't allow the usage of STUN (which is not your<br>
case), just it.<br>
<br>
Maybe your router has SIP ALG enabled?:<br>
