VoIP Definition: Voice over Internet Protocol (VoIP) technology refers to a series of transmission capabilities that make communication over the Internet securely. VoIP also known as Internet telephony, converts voice vibrations to compressed digital signals that translate to Internet Protocol (IP) packets. These IP packets are then transmitted and converted to a regular telephone signal if the user has a regular telephone. VoIP allows computer users and businesses to make telephone calls from a desktop computer equipped with a  Yealink VoIP Phone. Internet telephony offers services and benefits unparalleled by traditional phones.
