<div dir="ltr"><div><div id=":ud" class="" tabindex="0"><br></div>Dear Mr. Newton<br></div><div>Thank you for your response. I red the wiki and sip.conf sample file and I know about directmedia option. Actually these options are for times that you know about your connected networks (you know which clients are behind NAT and which are not). But my configuration is different. I have an A2Billing server + Asterisk (these two share a database using ARA); I also wrote a web service that allows users to automatically register and get a username and password. After registration users can connect to Asterisk to call other users. Here I want Asterisk to automatically detect when two users are behind the same NAT and redirect their traffic inside that NAT; this way the load of RTP traffic on Asterisk server will be reduced.<br>

</div>It is worth nothing that the official Asterisk wiki is at<br>
<a href="http://wiki.asterisk.org" target="_blank">http://wiki.asterisk.org</a>. If there is something missing from there,<br>
feel free to let me or someone in #asterisk-dev know and we'll make<br>
sure things get updated. One thing I do have on my to-do list is a NAT<br>
guide.<br>
