Voice over IP (VOIP) is an emerging technology allowing access to free or cheaper phone calls. VoIP services offer an alternative to regular fixed line phone services that may provide benefits to consumers.
VoIP calls don’t use the phone network. They route calls via the internet. To send voice across the internet, the voice information is coded into a digital format and transmitted in packets of information in the form of data. The data packets are then sent across the internet and reassembled into sound at the other end for the receiver to hear.
