In case you missed it, Google announced a feature in Gmail earlier this year that allowed you to place phone calls. What’s more is that phone calls placed to the US or Canada (from users in the US) were set to be free through the end of this year. With the end of the year coming up, the team over at Google decided that there were not enough free phone calls in the world, and extended their offer through the end of 2011. So open up your Gmail and start making some of those phone calls you’ve been putting off.
