After successfully integrating Voice and Video Chat in Gmail Google has taken another step forward and is now offering free calls to and from Gmail itself. Integrating Google Voice into Gmail users will now be able to send and receive free calls to the U.S. and Canada with calls to other countries at very low rates right from their web-browser without installing anything (Apart from Google Voice and Video Chat Plugin).

The feature is being rolled out to U.S. based Gmail users over the next few days, and can be used via “Call Phones” option which will show up in their chat-list once enabled(you will need to install Google voice and video plug-in if you haven’t already).
