What is VOIP?

What is VOIP & How it Works

VoIP stands for Voice over Internet Protocol. It refers to making phone calls that are made through the Internet, rather than through a regular landline or a mobile network. A VoIP system works by taking your analogue voice signals, converting them into digital signals, then sending them as data over your broadband line.

It’s a very useful way of making calls – for a start, once it’s set up it’s a lot cheaper than using normal phone lines. It means that, depending on your setup, you may not have to pay for your phone calls based on distance, which country you’re calling, or how much time you spend chatting.


Some broadband and home phone providers offer VoIP as part of their services so that they may do things a little differently. It’s the standard form of the phone line from a number of FTTP (fibre-to-the-premises) providers, for example, and VoIP is available as part of almost any business broadband or phone package. Either way, your provider will give you all the info you need.

Voice over IP, or VoIP, is short for Voice over Internet Protocol and refers to the transmission of voice traffic over an internet connection. Traditional telephony, known as the Public Switched Telephone Network or PSTN for short, works through physical phone lines, cable systems and networks and allows users to make landline and cellular telephone calls. IP telephony, however, is much more versatile and enables voice, data, and video to be transmitted to a variety of devices including smartphones, laptops, tablets and IP phones at a much lower cost.

There are a variety of applications and software communications systems that utilize Voice over IP to offer full-featured business communications solutions as well as internet telephony for personal use. Examples of such products include 3CX, which offers a company communications system integrating voice, video, chat and more. Most modern device manufacturers, like Apple, have integrated native IP apps into there smartphones, such as Apple FaceTime which provides call and video functionality.
