<p>Dear OpenSIPS-users,</p>
<p><br>
</p>
<p>I'm studying about NAT traversal with OpenSIPS, since last week. I also have found the documentation about the software MediaProxy (in
<a href="http://mediaproxy.ag-projects.com/">http://mediaproxy.ag-projects.com/</a>).</p>
<p><br>
</p>
<p>As long as I'm still getting 'kind of first steps' knowledge base about NAT traversal, I'm not interested, at least for a while, in MediaProxy software functionalities.</p>
<p>By the way, as a first contact with the NAT traversal mechanism, I just would like to let the INVITE from a caller reaches the callee, with caller behind a NAT. For this purpose I have 2 questions:</p>
<p><br>
</p>
<p>a) Am I free of using a kind of mediaproxy software, whether I want to build a prototype schema that will just creates and sends an simple INVITE, from caller behind a NAT, to a callee? That is, if I want just to run a simple test of NAT traversal, I don't
have to worry about mediaproxies, have I?</p>
<p><br>
</p>
<p>b) How could be an example of a simplest script code for that, considering that there is only one proxy for all peers and all of it is registered in such proxy using the same domain?</p>
<p><br>
</p>
<p>Any hint will be very helpful!!</p>
<p>Thanks a lot. <br>
</p>
