Without a doubt, applications and the Internet are leaving behind all the communication channels of the past. So much so that technological advances have already taken with them the much-needed SMS, these being replaced by messaging services such as WhatsApp, Telegram and others. But it is not the only thing, it also seeks to collect another victim, the telephone calls.
IP telephony could be considered 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.
To learn more about it and not leave you wanting to know how it works we have prepared this article for you, where we will detail everything you need to know.
What is telephony over Internet protocol and how does this technology work?
Voice over Internet Protocol telephony, better known as VoIP, originates from the English Voice Over Internet Protocol, and is not 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 we no longer have a telephone attached to the wall or tied to a table as it was in the past, but rather we have a mobile phone that works through the Internet, this is what we call VoIP. Namely, It is the one that enables the use of networks as a means 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 before, 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 away 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 fiber optics and satellites, using exclusive circuits to carry out a conversation, which translates into greater expense.
Contrary 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 many services where we can mention, call waiting services, call up to 3 lines, caller identification, among others.
As if that were not enough, it is beneficial for any operator, it reduces the cost and improves scalability by using standard data network components, makes it possible to develop a converged network for all types of communication, offers high telephone quality and much more.
What requirements must my mobile meet to make IP calls?
The necessary requirements that a mobile must have in order to make IP calls are practically non-existent.
Basically having a smart mobile phone is enough, since at least the equipment must have the Android 2.2 operating system.
Now if we talk about general requirements, in theory we should have a virtual or physical line, and an account in an operator with Voip services.
Which operators include Internet voice 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.
- monem 9.50 Euros per month.
- IP World 7.50 Euros per month.
- vozelia 19.00 Euros per month.
- telsome 4.13 Euros per month.
- netlip 9.95 Euros per month.
- Voice 8.90 Euros per month.
- Norvoz 4.9 cents per minute.
- Servitux 5.00 Euros per month.
- sarenet 5.00 Euros per month.
What alternative methods to VoIP exist to make free calls?
Next, We will see some of the best existing alternatives for VoIP calls:
Wi-Fi Calling
This technology is not very common, but it is by far one of the most promising in the future At least for users.
Since it provides the user with a mobile phone with this function, the ability to make and receive calls from remote locations with only a Wi-Fi connection, either to a home router or to a larger scale.
The most interesting thing about this is that the other person receiving the call does so as if it were a normal person. The same thing happens when a user calls you with a regular 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 oldest 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 and IP calls.
VoLTE
This alternative presents a great improvement to the technologies already seen before, by the fact that the quality of calls increases exponentially.
It is based on 4G network technology, so it is much faster and the 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. Nevertheless, 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.
Also, there is the fact that the connection can drop because the 4G network is not yet established in many places and its operation is different from the previous networks.
Skype
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 remains a very good technology for Internet calls.
WhatsApp
This application is positioned at the top as the best in terms of instant messaging. But also since 2015 it began to gradually distribute its call service using Internet Protocol voice technology.
By the time the service was complete it was a complete success that then it got better with video calls.
Telegram
It is one of the most famous free VoIP and instant messaging 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.
