We are currently facing an overwhelming technological revolution. A long time ago, communicating through conventional telephones was a quest. But now, establishing communication with others, regardless of distance, no longer has to be a problem. To update you a little, we invite you to know what VoIP is and what is it for in today’s world?
Before talking in detail about VoIP, it is necessary to explain what IP telephony consists of; since both terms go hand in hand. It is not possible to separate them. We count 1,2,3, and in five minutes, you will understand the concept of VoIP.
What is IP telephony?
We understand the term as all technological resources available for telephony and the internet united by the concept of VoIP. IP telephony is the protocol that allows the voice to be digitized and sent through the internet. Thus, giving rise to telephony being compatible with the world’s largest data network.
IP telephony is the tool most used today by different companies. It helps them update communication processes and allows them to be more effective. The system achieves this by replacing traditional calls that are often not optimal.
Who benefits from this type of telephony?
All those users who need a PBX are any telephone exchange directly connected to a public telephone network. So, they use trunk lines to call another telephone exchange. It is a device that belongs to the company that installs it, not the telephone company.
The attention of calls within a company, whether large or small, is streamlined by configuring a group of extensions.
Also, the administration of incoming calls can be automated, using call queues, interactive response memes, or IVR. The most important and practical of all is that databases are created on the information of each call, facilitating configuration changes. And they were visually monitoring each of them in real-time or when listening to the recorded calls.
What is VoIP?
VoIP is voice calls over the internet protocol. Those we make through WhatsApp, Telegram, Skype applications, among others, calls made directly over the internet network.
They have come as a new alternative to conventional calls that we have made for many years through telephone networks and antennas. Instead of depending on a nearby antenna, we rely on internet coverage, mobile data, or a Wi-Fi network.
How does VoIP telephony work?
The internet carries out this type of call through this procedure:
The mobile picks up our voice with the microphone to convert it into digital data. The network transfers them to the other device, where it interprets and converts them back into voice in both directions. Its operation is very similar to that carried out with videoconferences. It creates two scenarios within the calls, one for the voice you are sending and another for the voice on the receiving side. These calls must use the applications that have them.
This procedure has the advantage that it is not necessary to pay for a telephone rate. These rates can be costly depending on the country’s policies where you make the call. Each application has its protocol to work. It is impossible to call WhatsApp to Telegram or Telegram to Skype. This protocol is the opposite of traditional calls. It does not matter which operator you use to communicate with another person.
But, you must be clear that VoIP over IP systems is not exclusive to mobile devices. It is also possible to use them with the landline. For this, you can consider the following options:
- An IP voice router.
- An adapter for the phone.
- A telephone with IP voice.
They represent different solutions for the same goal, connecting the landline phone to the router and thus channeling calls through the internet network. But, it is necessary to pay for the device and operator that offers the service because it allows you to call everywhere in the world. You can do this without having to depend on the other person having the same application as us to talk to them.
How to make calls through VoIP?
So that you can make VoIP calls, it would help if you had specific software for the task. And this is where SIP (Session Initiation Protocol) phones come into play.
SIP is a specific protocol for telephony used to start, change or end calls over VoIP. Something like the HTTP protocol that we use on the internet. But for this case, it is a unique protocol for telephony.
It is necessary to have a SIP or VoIP phone to make these types of calls, among which you can find the ones mentioned below.
-
Hardware-based SIPs
These telephones are under the same aesthetics as traditional telephones. Still, they have hardware that allows you to make and receive calls through the Internet by VoIP. So it is not required that you buy a new telephone.
The only thing you need to do is use the fixed telephone with an ATA adapter. It is a device used to connect several analog model telephones to a digital system.
This connection is made using a unique key attached to a router with an RJ11 cable to make the IP call. It is a hardware adapter that allows making SIP calls with an analog telephone possible.
-
Software-based SIPs
In this case, you can use a smartphone, tablet, or computer with SIP software that gives us the possibility of making VoIP calls. The procedure is as simple as installing software or an application on any device that supports it. That software becomes compatible with IP calls.

Grandstream IP Phone Model GRP2601
One of the most recommended phones, and the most purchased, is the IP Essential. It is a two-line model designed for mass deployment and more practical management.
It has superior technology that reduces noise and excellent protection to be used at a business level. It is a Grandstream IP phone, which provides a centralized interface to manage and track Grandstream devices.
Conclusion
If you can update and walk hand in hand with the great advances in technology brings with it many advantages. One of which is that it reduces telephone rates by up to 80%. The integration of data and voice has greater precision. The best VoIP communication service to use is Inline.
