I’m sure many of you already know and love Gmail very much. It’s free, there’s tons of storage, and excellent customization. But did you also know that you can use Gmail to make free phone calls (if you live in the U.S. or Canada) to ANY phone number also within the U.S. or Canada? Here’s just a short list of cool things you can use with this free feature:

1. Easily wait on hold when calling customer service numbers without using up valuable cell minutes.

2. Call your buddies more quickly without having to even pick up your phone.

3. When you want to call someone without them knowing your phone number (because Gmail just dials out as a random number).

If you’re interested, here’s what you need to do to enable this functionality. First, make sure your computer has speakers and a microphone. Next, make sure you’ve got a Gmail account. If you don’t have one, you can sign up for one here. Next, you’ll need to install this plug-in from Google. The plug-in is compatible with Windows XP+, Mac OS X 10.4+, and Linux, so everyone is covered!

After you install the plug-in, hit the call phone button within the Chat and SMS window.  You should then see a dialer in the bottom right-hand corner of your browser within Gmail. From there, dial any number just like you would with a normal phone. If you use Google Contacts on your Google Account, you can also search for your friends’ names, and their numbers will be automatically dialed out of your address book. That’s it! Have fun calling for free from your computer!
