Doug has been using Magic Jack for his business. Leo says that's a good choice for smaller use, but it's important to remember that VOIP is always dependent on the quality and bandwidth of the internet connection. Also, there's latency as the packets often come out of order and must be reassembled. Leo uses a business solution, RingCentral. But for a sole proprietor, Magic Jack should work fine.
Doug also wants to know why he can't plug a USB key into his camera and download images directly. Leo says that the challenge is that USB is not a peer to peer system. There's a hierarchy, and that's why a USB drive can't connect to another USB port without a computer in between.
