VoIP or Voice over IP, is the future of making and receiving telephone calls. The technology involved is called internet protocol (the ‘IP’ bit of Voice over IP). It turns your voice into data packets and sends them instantly over your existing broadband network to the person you’re calling. The receiver notices nothing different; they still hear your voice as normal. The call quality will be very similar to, or the same as, that of any regular landline service. VoIP calls can be made either via your computer or through a regular phone handset. VoIP calls tend to be cheaper as they use the infrastructure you’ve already got in place to make and receive your calls.
