should come and go to the public IP address of the Adtran box (it does). They can make and receive calls fine with PSTN.<u></u><u></u></p>

<p class="MsoNormal">I understand more data is going to be needed, I will be glad to provide anything requested. I will actually be on site at the Mitel PBX customer’s location tomorrow morning, I plan on capturing some traffic on their network and inspecting
closely to see if it can be determined where some issues are happening with them. Probably unrelated to anything I’m doing, some IP phones on their mitel system are unable to make outbound calls, we see the call then immediately a cancel comes from them,
a couple IP phones and no digital phones on that system show that problem.<span><font color="#888888"><u></u><u></u></font></span></p><span><font color="#888888">
