Google is extending for another year the free calling feature available to Gmail users in the U.S. and Canada.
The Mountain View, Calif., company launched the "Call phones from Gmail" service in 2010.
"Many of you [use] Call phones from Gmail to easily connect with friends and family. If you're in the U.S. and Canada, you'll continue to be able to make free domestic calls through 2013. Plus, in most countries, you can still call the rest of the world from Gmail at insanely low rates," Google said in a brief blog.
