Obi 100 working OK, but for this annoying detail. We use my wife's google account for our Obi GV. I had listed two mobile numbers on our GV settings page for possible call forwarding when we wanted it, but they were inactive. Even so, when my wife tried to call our Obi-GV home number GV would invariably ask her to enter her PIN to access her account and would not connect whether she did or not. The only way to bypass this and allow her to call home was to delete her mobile number from GV.
