You already know Gmail integrated with Google Voice for free phone calls (and cheap international calls) from your inbox. But apart from using it to a friend, Gmail’s new phone calling capabilities introduce a lot of cool capabilities to your inbox.

If you’re logged into Gmail, and someone rings up your Google Voice number, you can see who’s calling on your computer without digging your phone out of your pocket.
