“VoIP”, or Voice over Internet Protocol, is a communication technology that uses the Internet instead of traditional analogue telephone lines for the purpose of making telephone calls. You can make and receive calls using data if you have WiFi or a decent 3/4G connection. A modern way of making a phone call if you will, and its quality is far superior to that of a traditional analogue line, although most people cannot tell the difference. Many people associate VoIP with consumer-type VoIP services; however, this cannot be compared. Utilizing business quality HD VoIP technology, we operate a carrier grade network to make calls to you. Our call quality is among the best available.
