Google's Call Phone plugin allows you to make cheap or free phone calls from your computer.
Google's Gtalk chat protocol allows you to exchange instant messages or audio/video links with anyone who has a free Google Account. Google has also created an optional plugin that allows you to call a phone number from your computer. Calling any number in the U.S. or Canada is free; numbers in other countries carry small fees. To add the Call Phone feature to Gtalk, you'll have to install the plugin on your computer.
Instructions
1. Open your favorite Web browser and navigate to Google's Call Phone page at google.com/chat/voice.
2. Click the "Install voice and video chat" button and follow the on-screen instructions to install the small plugin on your computer.
3. Go to your Gmail page by pointing your browser to gmail.com and entering your username and password if you're not already logged in. The "Call Phone" option will now appear in the left panel, just above your Gtalk contacts.
