Google Voice users in the US and Canada know that they can make free calls to others through either Voice or Gmail over the internet. It’s been a wonderful service that’s been completely free, surprisingly. It was only supposed to last until 2010, but every year they’ve extended the deadline. This year is no different, with Google announcing that the service will be free for another year, so all you Voice users can enjoy it for another year. Do any of you call others through Google Voice?
