I just recently purchased Obi 200 from Amazon. Just realized the Obi # located at the bottom of the device (which is the same on the box) is different from the Obi # in Obi system when I log into Obi 200. On Obi Talk website, the Obi # is the same as in Obi system. Is this normal or I should ask Amazon for a replacement? I'm able to add the device to my Obi account and activated Google voice.
