If you are calling another VoIP phone you will get a much higher quality call in full business quality HD VoIP. In any event, the call quality will be superior to what you are used to in both cases. That’s exactly why we don’t tie our customers into a contract, we don’t need to – we know they will love the quality, product and service at a fraction of the cost of a regular analogue service.

VoIP or “Voice over Internet Protocol” is a technology that uses the Internet to make telephone calls, instead of traditional analogue phone lines. That basically means if you have WiFi or a good quality 3/4G connection you can make and receive calls using data. Its a modern way of making a phone call if you like and the quality is far superior to your regular analogue phone line, although most people can’t tell the difference. A lot of people stereotype VoIP with consumer type VoIP services; there is no comparison. We operate our own carrier grade network that delivers calls to you, using business quality HD VoIP technology. The call quality is the best available from old and new technology.
