I am recent to using OBi with Google Voice. Almost every call I make via a 202 I get the same message, I hangup and hit redial and the call goes thru with no problems. I tend to believe there is more going on with Google as this is too commonplace to be any errors, but that is pure speculation on my part. Be patient, this is the best "FREE" service anywhere. I appreciate being able to have the service, let alone being free. My $0.02 worth
