Three ways to obtain the MAC address of a phone:
You can ask your supplier for the shipping information sheet which includes MAC
addresses according to the corresponding PO (Purchase Order).
You can find the MAC address on the label of the carton box.

phone.
Why cant I get a dial tone?
Check for any loose connections and that the phone has been installed properly.
