Google announced today that they are rolling out free domestic phone calls from within the Gmail application. Just to emphasis that again, you can now call any landline or mobile number in the United States and Canada for free using just a web browser, speakers, and microphone. In order to get the call button working from within Gmail, you will have to install the free voice and video chat plugin found here,  http://www.google.com/chat/voice/

Don’t worry if the Call Button doesn’t show up immediately within Gmail. A Google spokesman has stated that the roll out is still on-going and that most Gmail users in the US and Canada will be voice-capable within a few days.
