What is VoIP?

VoIP stands for “Voice over Internet Protocol” (in Spanish, Voice over Internet Protocol or Voice over IP) and is a technology that allows anyone to make telephone calls over the Internet that began to be used more widely towards the end from the 90s.

In fact, when talking about what VoIP is, it is normal that the term IP or IP address sounds familiar to you, since it is the way that computers, mobile phones and practically any device connected to the network have to communicate on the Internet. What’s more, today with the increase in broadband, VoIP has become the definitive choice for telephone service, not only for large companies but even for SMEs and consumers.

Are WhatsApp calls VoIP?

Yes, in addition to the phones and proprietary systems dedicated to VoIP that we will talk about below, we can say that today most of the apps we use to communicate allow VoIP. Some of the easiest examples are WhatsApp and Telegram that allow you to make calls over the Internet from one phone to another with VoIP.

How does VoIP work?

If we think about what normal phone calls are like (with lifelong phones) we find that when calling, our conversations are transformed and exchanged through small data packets through the global telephone network. Well, the only thing VoIP does is convert analog telephone signals into digital signals that can be sent over the Internet. It’s that simple!

In four easy steps, this is how VoIP works.

  • Your phone connects to the router of your local area network (LAN).
  • When you dial a phone number, your IP phone tells your VoIP service provider to call the other party.
  • Your VoIP service establishes the call and exchanges data packets from your IP phone.
  • The VoIP phone converts these digital signals into sound that you can hear.

This system allows incoming calls to automatically connect to the VOIP phone as long as it is connected to the Internet. Do you need to go on a trip abroad? Or do you want to set up your own office anywhere? Take your VOIP phone on the road, and wherever you connect it to the Internet, you can receive your calls. In this way, you do not need to have coverage and wherever you have a broadband Internet connection, you can use VoIP. As data, before we have explained one of the ways in which VoIP works, specifically the one that uses the IP address, but there are others such as ATA or direct connection between terminals.
