I have a OBi200 which has worked flawlessly for the last year. I am on the latest firmware (5757). I tried dialing my Google voice number by hitting **2 then the 10 digit number but only get a busy signal.
I then tried ***1 to get the OBi200 IP number and also got a busy signal. In fact dialing any star codes gets a busy signal.
This used to work up to this past summer.
I wonder if the master digitmap has changed recently.
