you can check if it IS setup. Once it's set up, on the setup page, it should have all the info about your device etc., otherwise, you might need to do it again.
I had Obi setup couple of years ago, never had problem, until recently. So my guess is the system had somehow changed, so it affected the settings we did before. When I clicked the setup button, it asked me to do couple of things, including going to google voice page to confirm it. (Obviously I had done it before, otherwise I wouldn't have the whole thing working for couple of years ...)
