Since June 12, Google Voice has failed to connect for my account with a "Connect Failed: 403 Forbidden" error.
I also have Google Voice with no number, used for outgoing calls only.
I've factory reset, remove the Obi200 from OBItalk portal, removed Google Voice TM from
myaccount.google.com/connections, and removed the Obi200 from
voice.google.com/settings.
On reprovisioning, Google Voice TM does get added to
myaccount.google.com, but the Obi200 does not get added to
voice.google.com. The 403 error is unchanged.
As a Canadian I can't (easily) get a number added to Google Voice.
Oh well, it was good while it lasted...
