I recently ported my home land line number to Google voice (Verizon FIOS to Consumer Cellular (AT&T wireless) then to Google voice). Now when a land line caller (Verizon) attempts to call they get a message "The number you are trying to call is not in service". However, when a call is made to the number from a cell phone (AT&T) the call is completed without incident. I have deleted the Obi 200 and reinstalled it. The situation remains the same. Where do I go from here?
