The transmission of voice calls over the telephone is Voice over Internet Protocol (VOIP). In this, optical packets are coated with audio signals and distributed over the internet. They turn back to the audio signals that the receiver processes after reaching their destination. VoIP Phone System has multiple features that keep it ahead of PSTN in terms of business communications and helps to increase productivity. Although relatively young in comparison to PSTN, VoIP has made remarkable progress in a short duration.
Although PSTN utilizes a network with a circuit switch; VoIP Technology uses a network with a packet switch. A dedicated route between the source and the destination occurs in a circuit-switched network or connection-oriented networks. Audio signals (for VoIP) are converted into packets in a packet-switched network or connection-oriented network, and these packets are separately routed from the source to the destination.
The traditional form of telephony where direct lines connect the caller and the receiver is the Public Switched Telephone Network or PSTN. A secure means of contact has been this conventional circuit-switched phone network. Even so, their success also nosedived in recent months. That was because of the dynamic circumstances and VoIP's rising popularity.
Why was the PSTN Declining?
The decrease in PSTN is directly related to the rise in VoIP usage globally. In the meantime, the consistency of the VoIP phone system was the key problem. However, the number of VoIP users is increasing steadily with the advent of higher internet speeds and technological improvements.
The number of fixed-line subscribers for both VoIP and PSTN has begun to decrease since hitting the high of 1.29 billion in 2008. While the PSTN decreased at a rate of 4 percent per year during this period, mobile VoIP users increased at a rate of 18 percent, accelerating the PSTN decline.
VoIP is an integral part of the field of telecommunication today. For individuals as well as associations, businesses, multinational businesses, and more; it has advantages. This is due largely to its characteristics. The features of VoIP reflect technological development, ranging from dirt-cheap voice calls to recent real-time video calls and conferencing, from instant messaging to file sharing.
In parallel to this, these user-oriented and user-friendly features are continually changing, with new modifications and enhancements continually being introduced. Because of all these advantages, VoIP is the go-to application for all contact styles in today's world.
Communication needs to be good for an organization to be successful. And all of that and more is supported by the VoIP phone system. What makes VoIP the most common alternative is a quicker, safe way of communication along with the feature of mobility.
Advantages of a Business VoIP Phone System
1- Scalability & Mobility
PSTN has to restart the entire installation phase to add an additional phone line. This restricts the right to add sections without extra costs being incurred. VoIP is coming to the defense here. VoIP Technology's scalability factor allows companies to increase and decrease without additional costs as needed.
2- Integration Into Other Systems
Businesses use a wide variety of other programs and technology to increase operating efficiencies. A number of existing business systems can be easily implemented by VoIP technology. Thus, without any alteration of existing software or IT infrastructure, companies can provide all the advantages of a VoIP system. VoIP integration with the cloud provides another range of advantages. This information is safely stored in a virtual service that can be accessed over the internet.
3- Cost
Cost is one of the key driving factors that has played a major role in promoting VoIP. In contrast to PSTN call costs, the cost of a VoIP call is negligible. In parallel to this, one might also make VoIP calls for free with a certain collection of variables, which for PSTN is not possible. In addition, the cost of installing, configuring, and maintaining VoIP phone systems is much lower than that of the PSTN system. There is no need for any heavy infrastructure, as the VoIP phone system is software-based. This saves the risk of more repairs.
4- Real-Time Audio & Video Call & Conferencing For More Efficient Contact
The VoIP Phone System provides different means of communication such as calls, conferences, messages, cloud storage, real-time interactions, and more. As well as they need a more powerful model of communication for companies to operate efficiently. A quicker VoIP communication method enables organizations to handle and work smoothly. Conferencing functionality is a big benefit for multinational corporations. This saves both time and money spent on planning the meeting. After that, interested individuals will attend the conference from their place and speak in real-time.
5- Other System Benefits
Although the word acronym stands for Voice over Internet Protocol, the VoIP Phone System is far more than just an Internet voice call. Apps such as caller ID, virtual numbers, phone numbers, voicemail, etc. are easier ways to boost operational performance by incorporating them. According to their specifications, companies may add or remove features. Although VoIP Service Providers typically include a common collection of features in a bundle, customization options are also available.
