Obi 200, working fine since April with google voice, one phone plugged directly into obi200. Recently, phone would ring; after answer no sound either direction. Call out, get dial tone, dial, ring tone, answered, no sound either direction. Dial **9222222222, get error tone, "There is no service available to complete your call".
Echo back also fails after delete the obi200 from dashboard, delete obi number from google voice account, and factory reset with paperclip with all cables removed, got red, green slow blink, green fast blink, release paper clip, red, then solid green after plug network cable in. Dial **9222222222, get no service available message. As if the obi200 is still configured.
Router/cable modem (Motorola MG7550) has obi 200 given static address, so that I should be able to specify dns servers 1.1.1.1 primary and 8.8.8.8 secondary in obi WAN configuration... Port forwarded UDP 10000 to obi static ip.
Reconfigure on google voice using Android Chrome. The terms and conditions show as grey substitute image with frowning one-eyed dog-eared paper document icon. Tapping it gives additional text "support.google.com refused to connect."
Accepting the invisible T&C proceeds to configuration page with 7 digit calling prefix, etc. Finish setup button leads to google choose an account, then
obitalk.com wants to access your Google Account, then Google Voice Account Confirmation, then back to SP config page, which vanishes if you don't tap a button, then device configuration page with SP1 google voice configuring <spinning dots>. This persists for an unknown duration over 10 minutes before red offline status.
