So much so that technological advances have already taken the much-needed SMS with them, these being replaced by messengers such as WhatsApp, Telegram and others. But it is not the only thing, it also seeks to claim another victim, the telephone calls.

IP telephony could be seen as the future, one that aims to change the way you think about calls. If you have never heard this term, it may seem strange to you, but we anticipate that With this you could save a lot on your monthly bill.

What is Internet Protocol Telephony and how does this technology work?


Voice over Internet Protocol telephony, better known as VoIP, originates from the English Voice Over Internet Protocol, and this does not it is more than a communication technology where the signal travels through an IP protocol. Not like others work through a cable.

To explain a little better, this works differently, because you no longer have a telephone attached to the wall or tied to a table as it was in the past, but we have a mobile that works through the Internet, this is what we call VoIP. That is to say, It is one that enables the use of networks as a medium for voice transmission.

What are the main advantages of using VoIP technology?

Without a doubt this offers great advantages, the most outstanding of all is that it is very economical. As we mentioned earlier, you save a lot of money with it.

Well, the main difference between traditional telephony and VoIP is that the former is based on distance and time of use, so the further it is and the longer it lasts, the more expensive it will be. On the other hand, the second is based solely on the exchange of data via the Internet.

This taking into account that a normal call requires several switchboards connected to each other through an optical fiber and satellites, using exclusive circuits to carry out a conversation, which translates into greater expense.

In contrast to VoIP, where we are compressing the voice signal and using a packet network when necessary. Packets of different calls that can travel through the same network at the same time without any type of interference and at a lower cost.

Another benefit is that this allows you to turn make calls from anywhere, of course as long as there is a connection to the broadband network.

It also offers numerous services where we can mention, call waiting services, calls of up to 3 lines, caller identification, among others.

As if that weren’t enough, it is beneficial for any operator, reduces cost and improves scalability by using standard data network components. makes it possible to develop a convergent network for all types of communication, offers high quality phone calls and much more.

What requirements must my mobile meet to make IP calls?

Mobile voIP

The necessary requirements that a mobile must have to be able to make IP calls are practically non-existent.

Basically having a smart mobile phone is enough, Since at least the computer must have the Android 2.2 operating system.

Now if we talk about general requirements, in theory we must have a line either virtual or physical, and an account with an operator with Voip services.

What operators include voice over Internet service in their rates?

Now we will see a list of the operators that present a better service in terms of VoIP with their respective rates:

  • Telefacil 6.05 Euros per month.
  • Monema 9.50 Euros per month.

What alternative methods to VoIP are there to make free calls?

WiFi Calling

Wifi calling

This technology is not very common, but it is by far one of the most promising for the future at least for users.

Since it equips the user to have a mobile with this function, of the ability to call and receive calls while in remote places and that only have a WiFi connection, either to a home router or a larger scale.

The most interesting thing about this is that the other person who receives the call does it as if it were a normal person. The same happens when a user calls you with a common call, but If we are with WiFi Calling, the other user will not even notice it.

It should be noted that most of the latest generation mobile phones already have this option integrated into their system. The older ones can only acquire it through a software update, this is because it is a function that is integrated and not as an app that can be downloaded.

WiFI Calling is an excellent alternative for normal calls and IPs.



This alternative presents a great improvement to the technologies already seen before, due to the fact that the quality of calls increases exponentially.

It is based on 4G network technology, so it is much faster and calls have better functions such as sharing files, videos, photos, among other things.

In theory it is much lighter than the others since it has higher data compression speeds. However, it has some limitations that are worth knowing, and it is that calls of this type can only be made with devices that have the same data operators.

Further, there is the fact that the connection can fall because the 4G network is not yet established in many places and its operation is different from previous networks.



This is the Internet voice technology designed by the great Microsoft company, from its beginnings to the present day it has always been characterized by an excellent service only surpassed in users by the newest messaging managers.

But still it is still a very good technology for internet calls.



This application ranks at the top as the best in terms of instant messaging. But also since 2015 it began to gradually distribute its call service using voice technology with internet protocol.

By the time the service was complete it was a complete success that later it got better with video calls.



It is one of the Most popular free instant messaging and VoIP services that exist after WhatsApp.

It is a service that fits perfectly on any device, It can be mobile, tablet or computer, in any of these it works perfectly as long as we have a good connection to the network.
