[slide37] Here's an example of one by BitCall a company in China, and it basically gave you a USB interface, a telephone line, and a telephony line interface, had a CODEC in it, you plugged it into your computer, and voilà, yes, you had Voice over IP service. Very cool, quite a simple little device.

So, I think at this point we'll take a 15-minute break, if that's okay, and then we'll continue and we'll talk further about Voice over IP gateways.
