<div>Hi,</div>
<div>&nbsp;</div>
<div>I am using .nat_uac_test to detect if the UA is from behind a NAT and if so use rtpproxy.&nbsp; However, if both UA are behind the &quot;same&quot; NAT, is there anyway to tell?&nbsp; If both UAs are from the same LAN then I don&#39;t need to apply rtpproxy.&nbsp; </div>


<div>&nbsp;</div>
<div>What would be a good way to do that?</div>
<div>&nbsp;</div>
<div>Any suggestion will be greatly appreciated.</div>
<div>&nbsp;</div>
<div>Regards,</div>
<div>Pete</div>
