I'm sorry if this is the wrong place to post this, but I couldn't find a more suitable website in the stackexchange network.

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?

I realize I'm kind of asking for free candy, but, if it's out there, I'd be a fool
