Sorry to reopen this thread. I have had everything working fine for over a year but I stopped getting incoming calls a week ago. Can make outgoing calls, Anveo reports that my OBIHAI is connected (their service would send me emails when it couldn't make contact with the box), but it doesn't look like incoming calls are being forwarded from google voice to the box.
When I go to Google Voice, legacy settings, I don't see the option to allow forwarding to google chat (see attached screenshot). Any idea what I am doing wrong?
