calling 800# in USA

Here is one strategy that I have used successfully. Go to voice.google.com and register a free phone number in the U.S. Then you fire up your VPN. (You do have a VPN, right? Try Atlas or NordVPN. There are also free ones.) Point your browser at the U.S. and at voice.google.com and you can make 800 phone calls.

Is Google Voice still giving out numbers?
I didn't think so?

It appears the answer to your question is yes and no. They are only available when someone gives up their free number. Pooh.

You can purchase a number for a monthly fee.
