You are likely already very familiar with Voice over Internet Protocol (VoIP) and just don’t know it yet.
This technology has been gaining popularity in recent years due to its cost-effectiveness, flexibility, and advanced features. It is what has given us Skype, Zoom, WhatsApp and many other communication tools that are part of our day-to-day lives.
VoIP allows users to make voice calls over the internet rather than traditional phone lines. It offers numerous benefits to companies and individuals alike, including improved productivity and increased mobility. During the COVID-19 pandemic, VoIP became even more present in our work routines.
This article will explore what VoIP is, how it works, and how businesses of all sizes can leverage this technology to improve their services.
What is VoIP?
VoIP, or Voice over Internet Protocol is a technology that allows voice calls to be transmitted over the internet instead of traditional telephone lines. It converts analog audio signals, which are the sound waves that we produce when we speak, into digital data that can be transmitted over the internet.
To use VoIP, all you need is an internet connection, a microphone, and a speaker or headset. You can make calls through an app on a computer or mobile device.
There are several different types of VoIP services available, including free and paid services. The most commonly used are free ones like Skype, Google Voice, and WhatsApp. However, paid VoIP services offer more advanced features.
What is the difference between VoIP and traditional phone systems?
The main difference between VoIP and traditional phone services is the way in which they transmit calls.
Traditional phone services use circuit-switched networks to transmit calls. This means that a dedicated, physical circuit is established between two callers for the duration of the call. Phone companies usually provide these communication services, which can be expensive, especially for long-distance and international calls.
VoIP, on the other hand, uses packet-switched networks to transmit calls. Data is transmitted over the internet, and since the internet is a shared network, multiple packets from different calls can be sent over the same physical infrastructure simultaneously. As a result, long-distance and international calls are cheaper.
Another key difference between VoIP and traditional phone services is the features they offer. While VoIP offers a wide range of advanced features included in the base price of the service, traditional phone services usually charge extra.
VoIP also offers more flexibility to users. It is possible to make and receive calls from anywhere with an internet connection. Traditional phone services require physical hardware and infrastructure.
How does VoIP work?
As explained, VoIP works by converting analogue voice signals into digital data that can be transmitted over the internet.
Here’s the step-by-step of this process:
1. The caller
The caller speakers into a microphone connected to their device. The analogue voice signals produced by the caller’s voice are then converted into digital data by a software called a “codec”.
2. Digital data
The digital data is then broken down into small data packets that can be sent over the internet.
These packets typically contain a small portion of the voice signal, along with information like the source and destination IP addresses.
3. Data packets
The data packets are then sent over the internet to the recipient’s device. This is done using the Internet Protocol (IP), which is the standard protocol for transmitting data over the internet.
4. Recipient’s device
The recipient’s device receives the data packets and uses a codec to convert the digital data back into analogue voice signals.
5. Recipient
The recipient hears the caller’s voice through a speaker or headset connected to their device.
In order for VoIP to work properly, both the caller and recipient need to have a reliable internet connection. The quality of the call can be affected by factors like network congestion, bandwidth limitations, and latency.
With advances in technology and improvements in internet infrastructure, the quality of VoIP calls has improved significantly in recent years, making it a popular choice for both personal and business communication.
The benefits of using VoIP services
VoIP calls have become more common and widely used. That is because there are numerous benefits to using VoIP for communication.
