We've come a long way from needing an operator to connect each telephone call by hand. Not only are the telephones in our houses more advanced but we can make a call from nearly anywhere with cell phones. In this episode we take a look at the next phone innovation: VoIP. It stands for Voice Over Internet Protocol and it's the technology used for calling somebody using your Internet connection.
