Google Voice Canada loophole and Google Hangouts Dialer

Google Voice has been available for several years, but it's U.S.-only. It gives you a free U.S. phone number that can forward calls for free to any other U.S. number, and includes SMS, voicemail and optional automatic voicemail-to-text-email transcription. You can pay for international long distance, but GV itself is free and always has been. You can sign up for GV using any existing Google account and a VPN. Just go to https://voice.google.com. But there's a catch: GV has no web phone app, it must link to an existing valid phone number, and that phone must be a U.S. number. Google makes a verification call to that number and you must answer and enter the 2-digit verification code they give you online. They will not accept a non-U.S. phone number, and you cannot create the GV account in the first place without an initial U.S. home number. You can use a VoIP account with a U.S. phone number, but a loophole that existed early on was that Google accepted 403 as a U.S. area code.
