Communication was much costlier at the start of the 21st century. Internet connectivity was limited to typing texts and sending emails. With the evolution of technology, communication became more real-time, though it was still finite to talking over text messages. The Internet revolution in the later years completely transformed the way how we connect with people around the world. The internet has become so advanced that it’s now possible for people to interact online by using their voice. This technology in simple terms is called VoIP.

 

Less than two decades old, voice over internet protocol or simply VoIP has seen tremendous growth in the past few years. It is a technique that allows users to make phone calls through their computer or phone by using the Internet as the medium. VoIP uses a series of hardware and software combinations which enables users to send voice as packets of data online using IP, and not by traditional circuit transmission of PSTN. 

 

So after reading this, the first question that strikes our mind is How do VoIP works?

 

VoIP technology uses codecs to convert audio into packets of data. These data packets are then transmitted over the internet by using suitable hardware devices. At the receiving end, the original audio signal is then recovered from these data packets, producing crystal clear voice quality. Codecs help in compressing the data for faster transmission; as a result, the voice quality is improved. These codecs encode the analog audio signals into digital, which after transmission are again decoded to original analog form.

 

Why is VoIP cheaper than traditional phone calls?

 

One of the most important advantages of using Voice over Internet Protocol (VoIP) is that it is way cheaper than traditional telephone systems. No matter how many times you call, or to which country you call, VoIP calls will always be low-priced. But have you ever wondered why VoIP is cheap? Well, there are many reasons for the cheap VoIP costs. This is mainly because VoIP telephonic systems are based on adaptive routing, in simple words, the data travels between routers all over the world. Due to this reason, all calls are charged on a domestic basis, no matter which part of the world you want to connect to. This way you can make unlimited calls to your loved ones all over the world, without having to pay hefty money.

 

 

With VoIP, the service provider manages the software and hardware infrastructure, giving you more time to concentrate on things that matter you the most. Hence it saves IT support bills as well. VoIP offers fixed charges, no matter what time of the day you want to make a call, you pay the same amount.

The VoIP telephone system is easy to set up and configure, moreover, there’s no need to pay for expensive hardware and software equipment, all you need is a reliable broadband connection and you are ready to make a low-cost internet call.

VoIP also reduces cabling costs as there are no extra cables required to set up a VoIP connection, unlike the traditional phone systems. As a result you can easily move your VoIP phone at no extra cost. VoIP users can send voice and data such as files, photos, videos using the same connection. Hence, reducing network costs by a considerable amount. VoIP is flexible; as a result, it is possible to carry out multimedia conferencing across the globe.

 

In conclusion, VoIP is the cheapest and the best possible alternative to traditional phone calls as they do not need more expensive technology to carry out. Switching to VoIP is an ideal way of cutting down the burden on your pockets. Also, improving technology is making it easier to use, more user-friendly and reliable. Though being born a less than two decades ago, VoIP systems have revolutionized how we communicate with our businesses and loved ones all around the world.
