VoIP is not a commonly understood term, and people often get confused when they hear it. So, what is VoIP? VoIP stands for Voice over Internet Protocol.

It is making phone calls using an internet connection rather than a mobile or landline network.

Since VoIP is more efficient than regular telephony, it consumes lesser resources and thus costs less. VoIP is useful in making long distance calls and for high-quality video conferences as well.

With adequate internet data and high-speed connections, you can make audio/video calls using VoIP without paying in terms of the distance or call durations.

Not just for the big guys

One of the many misconceptions around VoIP is that it is suitable only for big businesses or tech giants. Absolutely NOT.

VoIP offers huge benefits for any level of business, but before we discuss them, let’s understand what VoIP is in detail.

There are three different ways to make VoIP calls. Each has different resource requirements:

1. With a landline phone and VoIP adapter

You need special adapters that fit into your landline phones or routers for making the VoIP calls.

2. With a computer, Wi-Fi and VoIP app

You need a PC connected with Wi-Fi along with an app for making the VoIP calls. There are several popular apps that provide a good call experience:

  • Skype
  • Google Voice
  • Facebook Messenger

Making calls from the app to another person on the app is free, but making calls from a web app to a phone number might incur a fee.

3. With a smartphone, Wi-Fi and VoIP app

You need a smartphone, Wi-Fi and an installed app on the phone to make the VoIP calls. Again, there are several apps — WhatsApp, Skype, Apple FaceTime — that make voice calling easier to another person on the same app.

If you are facing some issues with VoIP call quality, a slow connection might not always be the reason. The more number of employees you have on a call, the higher the bandwidth needs to be to handle VoIP calls.

There is a lot of confusion over the usage of VoIP in India, whether it is legal or not. As per the “Recommendations on Regulatory framework for Internet Telephony” released by Telecom Regulatory Authority of India (TRAI) on October 24, 2017, it is legal to use VoIP communications through apps on your PC or smartphone or through VoIP-adapted phones.

For businesses in India, it is completely legal to use VoIP communication services.

What you cannot do in India is set up VoIP gateways that convert the VoIP call to a plain old telephone service (POTS) or a regular phone call.
