too add to this... I have rebooted the OBIs several times as well as the router and the cable modem. When I call one of the Google Voice numbers, it immediately rings on the computer and the cell phone, but not the pots line. If I answer the pots line, I get OBI dialtone.
If I call the google voice number from the POTS OBI line, I do go right into voicemail, so it is the correct Google Voice number assigned to the line, it just wont ring and it is not a matter of the OBI device not powering the ring... the OBI device does not see an incoming call coming in.
