I currently have no phone number; I can make outgoing calls via the widget in gmail, but I cannot receive calls (as far as I know). I know that you can set up a google voice number to forward to Google chat, and this is exactly what I want. The problem is, I can't get a Google voice number in the first place, because it first requires that I have an existing phone number, even if I wouldn't use it.
So, it is possible to skip providing an existing phone number, and just get a google voice number that forwards to Google chat?
Alternatively, is there any free phone service that can be used without a phone and lets you receive calls from any number?
