I have a Vtech phone connected to my Obi100, and wish to use it for calls coming in to my Google Voice number. When I attempt to add that phone as a new phone to Google Voice using my Obi phone number, however, Google indicates that "country of the forwarding phone does not match your country", and it will not add the phone. So, that Vtech phone obviously never rings. Can anyone tell me what I'm doing wrong? Thanks!!
