Traditionally, a phone conversation is converted to electronic signals that traverse an elaborate network of switches in a dedicated circuit that lasts the duration of a call. In Voice over Internet Protocol, your conversation is converted to packets of data that travel over the internet or private networks, just like emails or web pages, through voice packets that get priority status. The packets get re-assembled and converted to sound on the other end of the call. The quality of the service is nearly identical to, or sometimes better than, traditional phone service. You may use any number of computers on your broadband service while talking on the phone. The system automatically gives priority to your voice traffic to ensure quality of service.
