+1 for the GV/Obihai setup

The Obihai 100 box has been rock solid after 2 years of use. We have 2 GV accounts associated with the device. It worked great when we lived in Denver and it works great here in London.

I've been tempted to buy the 202 because of the additional features, T38 fax and bluetooth/wifi adapters, but don't need the fax capability bad enough to justify it.
