My obi 100 service was cut off and I was told I had to buy a 200, which I did, but now read that is not true? So, my service was cut out before Christmas (gee thanks) and I have an emergency I need to call with no service. Got my new 200, with no replacement instructions on how to keep my google voice number, or set up. Called an emailed several times with no call backs or help of any kind. Will be returning product, can't use without setup instructions.
