Also note: if the device gets an IP address, and you can go to that IP address on a web browser (with default user ID and password both "admin"), then look at the Status-->PHONE port status, you should see "on hook", VBAT approximately 58 V (11.8 V), and TipRingVoltage approximately 45 V. If any of those voltage values are off by more than a few volts, then the device's telephone interface chip is dead. Did you have it plugged into the building's telephone wiring? That would be a prime entry point for a lightening surge.
