The Revolution of Voice Over Internet Protocol- Benefits, Disadvantages and How to Setup
Voice over Internet Protocol (VoIP), also known as Internet telephony, is a product that is rapidly transforming the telecom business and how people communicate.

The advent of VoIP services signals the end of the old telephone industry. VoIP is a new technology that makes phone calls over the Internet rather than the old public switched telephone network (PSTN), which has been in use for more than a century. VoIP allows users to make free phone calls over a high-speed Internet connection, undermining the current telephony pricing scheme.

The use of packet-switched internet protocol (IP) networks to relay a voice communication is referred to as VoIP. VoIP has both advantages and disadvantages in terms of security.

What is needed to make a VoIP?
Voice-over Internet Protocol systems come in a variety of shapes and sizes. Virtually any computer is capable of supporting VoIP services.

Benefits of VoIP for business individuals
Low cost of operation
When compared to other ways of communication, it is inexpensive.
Because it consolidates all of an institution's electronic traffic, Voice over Internet Protocol is inexpensive. For each sort of traffic, an institution does not need to purchase separate private branch exchange tile lines.
Even if the VoIP system is costly to install, a firm can save a lot of money by operating a single network.
The cost of operating a telecommunications system is not borne by an institution. Furthermore, the system administrator's job becomes less demanding. Instead of managing many networks, the administrator only has to deal with one.
A corporation doesn't need to hire separate employees to manage voice and data networks.

High speed and quality of phone calls
When compared to the old public switched telephone network, Voice over Internet Protocol can save bandwidth and improve communication quality.

Conference calling
Conferencing is much simplified without the use of dedicated phone lines. Conferencing is possible with traditional phone systems, but a company will have to pay for an additional service and host several callers each time they need to conference.
These functionalities are often native to a converged data network, and the cost is integrated into the already low price of the VoIP service the business is already paying for.

Video calling
During phone or video calls, VoIP may transmit multiple media types like photographs, videos, and text, greatly improving the capacity to conduct presentations and resolve issues as they arise.

Fax via VoIP
Most VoIP companies feature Fax over IP as part of their service, which is one of the additional advantages of VoIP. Fax over IP almost reduces the high costs of long-distance facsimile while also improving equipment compatibility and service reliability.
To transmit or receive a fax, VoIP does not even require the use of a fax machine.

Effective mode of communication
Keeping employees within reach is crucial when they are working from different locations within the office, from home, or all across the world. One of the more intriguing features of VoIP is that a single call can be routed to your desk phone for the first few rings, then to your mobile phone, tablet, or laptop if the call stays unanswered. As a result, more essential calls are addressed and less time is spent checking voicemail or communicating via other platforms.

Disadvantages of VoIP
VoIP has some disadvantages as well, but most of the time it is not a major one. Some of them are as follows,
Network bandwidth
The internet connection determines the quality of these service. If the network bandwidth is insufficient, the service will decline.

VoIP does not consume nearly as much bandwidth as one may think. VoIP devices on the customer's network must have low latency. Each device should have a minimum upload speed of 100 kbps. Ping and jitter, which evaluate the latency and stability of your internet connection, should be less than 70ms on a good connection.

The amount of bandwidth required for commercial purposes is determined by the number of concurrent calls that will be made. Running a bandwidth test on the present network is the best approach to find out.

Latency and jittering
When interacting online, each message is broken down into "data packets," which are small bits of data. The original message is then reconstructed from these packets at their intended destination.

Latency and jitter occur when data packets experience delays in transmission or are reassembled incorrectly.

It's possible that the problem isn't with one’s network; large internet backbones alter data routes to ensure that traffic is delivered consistently and on the shortest way to its destination. These modifications happen on their own, with no input from customers.

Location tracking during emergency situations
Third parties have a hard time determining where a call originated because of VoIP's portability and accessibility.
There is no way to track the calls because they originate from an IP address with no GPS data or cell tower information. While 99 percent of callers do not require this information, it can pose a problem for emergency services such as ambulances, police, and firefighting.
VoIP requirements for business and office
The process of installation in business is easy. The company should keep in mind that this is an investment that will last for years to come so it is preferred that the company invest a good amount of money in setting up b

They should definitely have a very good stable Internet connection.

When it comes down to hardware required, even with a hosted solution, the firm will require IP handsets or adapters in order to use their existing phones with the VoIP service. Most companies choose to utilize a mix of clients, such as adapters for a few phones, IP handsets for senior executives, and softphones installed on most PCs and laptops.

Many businesses now employ mobile VoIP clients as a result of the growing popularity of mobile devices.

While it may appear that there is a lot of gear, purchasing and maintaining it is not extremely expensive.


VoIP requirements for remote workers and homes
This is essential in work from home kind of business and for general communication needs of a house.
It requires a very good stable internet connection. The optic fibre network is the preferred solution
As a backup in case of an outage, it is recommended to have a cellular connection as well.
Generally, there need not be any additional requirements for using VoIP. Everything a consumer needs is a computer system that supports VoIP.

Conclusion
In conclusion, even with its flaws, VoIP is an excellent solution for communication for all. The pros weigh more than cons when it comes to VoIP.
