I am having trouble setting this new device up. I have tried several different FW versions (even though I see where somebody says this won't matter). I tried resetting the device, changing the DNS to 4.2.2.2, checking and unchecking Google Voice setup, and it still won't add the device. I can get the echo test and I see in the network settings where it recognizes when I pick up the phone.
There are 2 green lights on the device and the hardware appears to be working properly.
Are there any further troubleshooting steps I can take before I return this thing?
