I use an Obihai (202 model) with Google Voice, too. I also have a 'real' IP phone that connects directly to the Internet. The other boxes, called ATAs, allow the connecting of a traditional phone to the Internet. Each have their advantage and both are cheaper than a landline.You might want to give this option a try. It only cost you the price of the device. I have been using it for years now. Google ended support for this device but they are now "officially supported" by google. Anyway: after your initial setup you have no recurring cost. I posted a detailed thread about it here http://www.tractorbynet.com/forums/related-topics/285488-great-voip-telephone-service-update.html
I detailed what you need to do to port your existing phone #, although it is a bit easier if you use a random google number.
Good luck, Dave
