We have a working Obi202 device and Google Voice. It will run for days or weeks, no issues. Then we will try to make an outgoing call and will get a "device is not configured" error. Resetting the Obi will bring it back to life. Internet service is Comcast and reliable, never had an outage. The Obi has the latest firmware running (3.0.1 (Build: 4041)). How to fix?
