How Does VoIP Work?

Questions You Should Ask Before Choosing A VoIP Provider

There are few different ways VoIP technology works, the first is through what is known as an ATA or analogue telephone adaptor. The ATA allows you to connect your regular phone to your computer or internet connection so you can use VoIP. This adaptor allows users with phones dating as far back as the 80’s to connect to the internet and use VoIP and this means you can do away with large phone bills for good.

The second method is to purchase an IP phone which connects to a computer through an Ethernet connector on one end and allows you to make calls. There are also what are known as Wi-Fi phones which are basically the VoIP equivalent of a cordless telephone. If you are employed by a company where your job entails making lots of calls whilst sitting in front of a computer screen you are probably using an IP phone already.


The third method is computer-to-computer. Anyone who has used Vonage or Skype will have made a computer-to-computer call. All you need is an in-built microphone and speakers and you can download the software and start making free calls over the internet. All three methods essentially digitise your voice and covert it into data and send it over your internet connection where it is reconverted back into audio on the receiver’s end.

What are the advantages of VoIP?

As we have mentioned time and time again, the main benefit of VoIP is it lowers your monthly phone bill. Computer-to-computer calls are free of cost. Computer to landline calls are significantly lower than traditional phone calls. All you need to do is pay your internet bill on time. Traditional telecoms companies used to be limited by the number of lines they could add. With VoIP there is no such concern and an infinite number of lines can be added. The only limitation is bandwidth. These days VoIP call quality is even better than what you get from a traditional telephone.

How to get VoIP

You can sign up to a service like Vonage which will offers a variety of packages for a monthly fee. Alternatively, you can use free services such as Skype or Google Voice. There are tons of service providers out there who will add features and personalise your plan especially if you are going to be making plenty of calls every month so do shop around.
