Hi guys,
There is no double NAT on my network. I have one mikrotik router doing NAT for the whole network. No customers are using their own routers, I supply some customers a router, but it does not NAT, it just routes.

PUBLIC IP <-> NAT <->BRIDGED WIRELSS NETWORK <-> VOIPo ATA

I guess I'm not sure whether the problems I am having are due to using the HT286s or my NAT/routing. I'm going to set up a couple boxes tonight to test over the weekend.

I'll install an HT286 with a real public IP. Then I'll also install your supplied RT31P2 on a private IP through NAT. We'll see which one works the best.

On my HT286 boxes should I be using STUN? When I tried once to enable that and point it at sip.viopwelcome.com it detected the right public IP but the call only had audio one way.

When I have any more failed calls, I'll make a note of the call ID. How should I best relay that information to the right person at VOIPo?
