What is VoIP?

Voice over Internet Protocol, or VoIP, is a type of communication technology (comprising both hardware and software) that allows you to make phone calls using an internet connection rather than a traditional analog phone line that uses wires or optical fibers to make a connection. VoIP is also known as internet calling or IP telephony.
 

VoIP is transmitted through various methods, including traditional phones, smartphone apps, computer software and specific VoIP-enabled phones.
