9.2. Wi-Fi Internet Phones

One day, someone asked an interesting question: why do I have to leave my broadband phone calling advantages at home? Why can't I take them with me to the coffee shop?

Now you can. Several vendor phones let you dial to your broadband phone account through any public Wi-Fi network. When you reach a hotspot, the Wi-Fi phone connects to the wireless network and reaches your phone provider to initiate your calls.
