No doubt that Phone calls are one of the most beneficial communication channels in our times. But did you know that you can make or receive phone calls without the service of your local phone company? Enter VoIP.


What Is VoIP?


VoIP is an acronym for Voice Over Internet Protocol. Imagine you are using a normal phone but using the Internet instead of your local phone company. You can make and receive calls like an ordinary phone. On top of that VoIP can offer a ton of different features that your traditional telephone service may not have.


How does VoIP work?


The traditional telephone uses analog lines while VoIP needs no hardware at all. Local telephone companies always support the use of Analog phones or landlines. This is not true when it comes to VoIP. It is so simple that it does not use any other hardware.

VoIP providers send information through a high-speed internet connection. Your phone calls get converted into data and it will get sent through your Internet.

VoIP service has several advantages over traditional phone service. We will discuss that later in this article. 

One of the core principles of VoIP is that it converts your audio signals into digital signals. In this way, users can make Phone Calls while bypassing the telephone company. 

VoIP is a great upgrade from an analog phone system, which can be pretty old school, if you ask me.

A VoIP system doesn’t rely on traditional phone lines. Instead, VoIP transmits data over the internet and sends and receives voice calls when in use. Since VoIP can’t reach any phone on its own, a cloud-based phone provider needs to complete the call. 

Using the Wi-Fi, users gain the following features:

Two types of VoIP telephones


  • Hardware-based VoIP phones 

This kind of VoIP phone looks like a traditional hard-wired or cordless telephone. It includes similar features, such as a speaker or microphone, a touchpad, and a caller ID display. This VoIP phone can also provide voicemail, call conferencing, and call transfer features.


  • Software-based VoIP phones 

Software-based VoIP phones are also known as softphones. They are software installed on a computer or mobile device. 

The softphone user interface often looks like a telephone handset. This handset comes with a touchpad and caller ID display. 

A headset equipped with a microphone connects to the computer or mobile device to make calls. Users can also make calls via their computer or mobile device. This is possible if they have a built-in microphone and speaker.
