This document discusses VoIP (Voice over Internet Protocol) telephone systems and their advantages over traditional phone systems. VoIP converts voice into data packets that can be transmitted over computer networks and the Internet. A VoIP system provides a modern phone system with many features through a single software solution installed on a company's computer network. It allows phone extensions to be added anywhere there is an Internet connection. VoIP systems offer lower costs, flexibility, and integration with other business applications compared to traditional phone systems.
