<p>Dear OpenSIPS-Users,</p>
<p><br>
</p>
<p>I'm working in a project that needs to use OpensSIPS, SIP over TCP, softphones behind NAT, and video transmission between the sip proxy and the softphones as direct media.</p>
<p><br>
</p>
<p>As I'm completely new to NAT traversing and direct media, I wonder what is the first module to study?</p>
<p><br>
</p>
<p>Nat Traversal, or Media Proxy, or Nathelper?</p>
<p><br>
</p>
<p>What of these 3 modules will be really necessary, to provide direct media, when using SIP over IP and peers behind NATs?</p>
<p><br>
</p>
<p>Any hint will be very helpful!<br>
</p>
<p><br>
</p>
Regards.
