VOIP is Voice Over internet Protocol. It is a technique for converting an analog telephone connection to digital, sending it over a computer network, and converting it back to analog at the other end. The typical bandwidth required for a telephone conversation is 56kbps. In fact, this is how the telephone companies work. What we call VOIP is an extension of that technology to allow use within a business, or to allow telephone calls over the Internet. In a business application, the network architecture usually supports a QOS (Quality of Service) parameter that gives precedence to VOIP traffic over data traffic. Often, with Internet telephone support, the QOS is not set nor supported, making the conversation subject to breaking up. Just like some cellphones.
