I really want to do a review of Google Voice on my site, but I haven’t received my invite yet.

Does Google Voice allow you to set up GV numbers that correspond to phone numbers you don’t own? For example, let’s say I have 4 family members scattered across the US. I want to be able to call them from my home phone with no fuss, and not pay for long distance.

So I set them up with these numbers:
(319) 555-0001 (speed dial 1 on phone)
(319) 555-0002 (speed dial 2)
(319) 555-0003 (speed dial 3)
(319) 555-0004 (speed dial 4)

Would this work? Or does Google call your target phone number in order to authorize a GV number forwarding to the target number?
