What is VoIP?

As you already know, the full form of VoIP is Voice over Internet Protocol, and it essentially can be understood as a technology, which enables us to make phone calls over the Internet, using some physical devices. It is especially very suitable for businesses, whether small or giant, as it comes out to be a modern and convenient way of communication.

Let’s take an example so that we can better understand the VoIP thing. WhatsApp is used by billions of people, and when you are doing a call on WhatsApp, instead of the traditional type of calling, it is done through the internet, so, we can say that calling on WhatsApp is a VoIP feature.

So, roughly you can consider VoIP being like a fancy name for sending your voice over the internet instead of the traditional communication channels like landline services. This can be a very convenient, and modern approach to calling, even for individuals, and businesses.

A VoIP number is basically like a virtual phone number, and you can use it like your regular number, except that the calls will be done through the internet.

Many phone services are there, which use VoIP to provide powerful telephone services to their customers, instead of giving a heavy physical installation and maintenance of a physical Telephone. Later on, we will try to list out some of the dedicated VoIP services, but right now, I think it’s better to understand more about the technology, but we are not going to go into complete details, and just understand some basic things about it.

How does VoIP work?

You might be already familiar with the kind of traditional calling service, where the the calls must be routed through a local telephone company. But when it comes to VoIP, it uses some broadband connection and routes the call along the most efficient path.

So what happens is that VoIP services convert your voice into a digital signal and that digital signal is made to travel over the internet. Also, if you are calling a regular phone number, the signal is converted to the regular telephone signal before reaching the destination.

So, with VoIP, we can easily call directly through a computer, through a special VoIP system Phone, or even a simple telephone, connected to a special adapter.

So, this simple way we can understand VoIP service. Anyway, we are not going into great detail about how VoIP works, but I think the above explanation helps at least get a rough idea of how VoIP works. If you want to get into more details of it, you can search over the internet and learn more about it.

What is the difference between Traditional calling and VoIP
