Well...Google has added another interesting feature to Gmail. It is the Call Phone feature. You may have seen a message pop up yesterday (Aug. 27th) about this option. It then actually appears over in the Chat area and simply says "Call Phone". If you are first time user, you may have to install the Voice and Video Chat download first.
Unfortunately the PC I was on at home does not have a built in microphone, so I hooked up my external Mic. Then...I gave it a try. I went ahead and called Noah on his dad's phone. Worked beautifully! Gotta love Google, as they are expected to be innovative and continue to make improvements to their tools.
