Any help would be greatly appreciate, I have about 20 pcs of Obi200 and none of them seem to work, says NO LINE, usually working model does not say no line, phone cords are fine, inside does not seem to have any visible burnt out chips or anything, the most of them have only power and ethernet indicators working, some do have phone led also working but still says NO LINE, any idea what could be wrong with them? if anyone knows is it common issue with those models? I can login into IP of the device, and I did firmware update but did not help.
