<p>I&#39;ll find the command line to do a more detailed packet dump that can be loaded into wireshark for further analysis. The main thing I&#39;m wondering is if Nat is doing something funny with rewriting the rtp and rtcp port numbers.</p>


<p>What type of NAT do you have? You can use WinStun or another basic stun client to find out. </p><div class="elided-text">

<div>...I&#39;m not sure if that will tell much. Where it says bdfoster-Precision-WorkStation-490, that is the FS server (192.168.1.79), the ATA is on 192.168.1.80 (Grandstream HT286) This problem has also occurred using a SPA921 and another HT286, all on the same LAN connected to the same server, etc.</div>

If the (ADSL) router has a (for lack of a better term cause I can&#39;t<br>
remember) &quot;SIP helper&quot; app, try disabling it. Similar to the Cisco &quot;SMTP<br>
Fixup&quot; functionality which does an excellent job at the opposite.<br>
