Voice over Internet Protocol (VoIP) is a technology that allows phone calls to be made over the internet rather than through a traditional circuit-switched phone line. VoIP has been in the mainstream for more than a decade; however, only in the past few years has it really taken off in popularity.
Since VoIP works over a high-speed internet connection, as network capabilities improve, adoption of VoIP has grown alongside. The global market share of VoIP is expected to reach $55 billion by 2025. 1 With the recent rise in remote working, VoIP has gone from a nice-to-have to a necessity for businesses.
The foundations of VoIP technology have not changed substantially since its introduction in the late 1990s. It is the evolution of how VoIP is used across multiple calling environments that has revolutionized telephony – especially when softphone technology is implemented on mobile. Softphones provide access to all the benefits of a VoIP deskphone but on a mobile device.
A softphone is not really a phone at all, at least, not in the physical sense. Rather, softphones are applications installed on a mobile device or computer that uses VoIP technology to make calls over the internet. 2 The softphone application requires a SIP connection, that is provided by a VoIP carrier, to work.
VoIP’s compatibility with mobile devices frees people to work from anywhere, seamlessly transitioning from the office to remote without the need to change appliances or phone numbers. In addition, VoIP is appealing to organizations because it is cost effective, provides scalability, and helps to unify communications across the company.
VoIP is a rapidly developing technology. The quality of the call depends on the speed of the internet connection and available bandwidth – either of which can cause a delay, or latency, if overburdened. Tools and technologies exist today to overcome these challenges and provide quality conversations across multiple calling environments.
