Just making this thread in case someone runs into this in the future:
Recent builds of the Ooma firmware have issues with the NAT acceleration in Asus routers. You'll just get the blinking red logo forever, even though the device will be on the Internet just fine. Long story short - tons of troubleshooting, replacing Ooma hardware, etc, etc... all you have to do is turn of NAT acceleration on your Asus router. Tried every other setting you can think of - NAT loopback changes, port forwarding, UPnP, static IP, whatever.
Maybe either party will fix this one day, but for now, that's the fix.
