Who Invented VoIP?

Overview of VoIP

VoIP (Voice over Internet Protocol) refers to a technology that transmits voice signals over the internet rather than using traditional phone lines. It has transformed communication worldwide, allowing individuals and businesses to communicate more efficiently and at a lower cost. By shifting the mode of transmission from circuit-switched networks to packet-switched networks, VoIP has enabled the integration of voice, data, and video on a single network.

History of VoIP

The concept of transmitting voice messages over a data network was first explored by researchers working on ARPANET in the early 1970s. However, it was not until 1995 that the world's first commercial VoIP service was launched by VocalTec, an Israeli company. This offering allowed users to use their personal computers equipped with a microphone and speaker to make calls over the public internet.

For many years, the adoption of VoIP was limited due to technical issues such as poor sound quality, dropped calls, and slow data transmission speeds. These issues slowed down the momentum of VoIP, and it was not until the early 2000s that VoIP began to gain mainstream popularity.

Early Innovators of VoIP

The founding members of VocalTec, Alon Cohen and Lior Haramaty, were the early innovators of VoIP. Cohen was inspired to develop the technology when he encountered the high cost of international phone calls while studying in the United States. He realized that by shifting the transmission of voice signals from circuit switches to packet switches, he could create a more efficient and cost-effective system for voice communication.

Cohen and Haramaty developed the first-ever VoIP software, which permitted users to make voice calls over the internet using a computer and a microphone. This breakthrough made VocalTec the pioneer of VoIP technology, and the company continued to innovate and improve on the technology with subsequent releases of their software.

Today, VocalTec has evolved into a global provider of VoIP equipment and services, and its technology has become the basis of many modern cloud-based communications platforms. The invention of VoIP by Alon Cohen and Lior Haramaty has changed the way people communicate and has paved the way for the development of new technologies that have revolutionized the telecommunications industry.

Who Invented VoIP?

Voice over Internet Protocol, or VoIP, has become an essential tool for communication in the modern digital age. But who invented VoIP technology? Contrary to popular belief, it wasn't one single individual who can be credited with the invention of VoIP. Rather, it was the cumulative efforts of many innovative minds over several years that led to the development of this revolutionary technology.

The Early Years of VoIP

The concept of transmitting voice over the internet was first explored in the 1970s, but it wasn't until the early 1990s that VoIP technology started to take shape. VocalTec Communications, an Israeli telecommunications company, released the first commercial VoIP software in 1995. This software allowed users to make low-quality calls over the internet using a microphone and speakers connected to their computer.

However, it wasn't until 1998 when the first successful internet phone call was made. This call marked a significant milestone in the development of VoIP technology and opened the doors for further innovation in the field.

The Contributions of Cisco Systems

One of the companies that played a significant role in advancing VoIP technology is Cisco Systems. In 1997, Cisco acquired a company called Selsius Systems, which had developed a VoIP phone system. Cisco then continued to build upon this technology, releasing its own VoIP phone system in 1999.

Cisco's VoIP technology was initially aimed at business use, but it quickly gained popularity among consumers as well. The company's VoIP products, such as the Cisco ATA 186 and the Cisco 7900 Series IP Phones, helped to accelerate the adoption of VoIP technology in the early 2000s.

The Contributions of Skype

Another significant contributor to the development of VoIP technology is Skype. Launched in 2003, Skype was the brainchild of Niklas Zennström and Janus Friis, two entrepreneurs from Sweden and Denmark, respectively.

Skype's early success can be largely attributed to its simplicity and ease of use. The software allowed users to make free voice and video calls over the internet using a computer and an internet connection. Skype quickly gained popularity among consumers and paved the way for future VoIP apps and services.

Further Developments in VoIP Technology

Improvements in Voice Quality

One of the most significant developments in VoIP technology has been the improvement in voice quality. Early adopters of VoIP technology often experienced poor quality when using the service, but this has improved significantly over the years thanks to advances in network infrastructure.

VoIP and Mobile Devices

The proliferation of smartphones and other mobile devices has also contributed to the growth of VoIP technology. There are now numerous apps that allow users to make voice and video calls over the internet for free or at very low cost, which has disrupted the traditional telecommunications industry.

The Future of VoIP

Experts predict that VoIP technology will continue to evolve and become more integrated with other communication platforms such as instant messaging and social media. The rise of 5G technology is also expected to boost the growth of VoIP technology, enabling even faster and more reliable communication worldwide.


While VoIP technology does not have a single inventor, it is clear that the contributions of many individuals and companies have led to the development of this revolutionary communication tool. With the ongoing improvements and advancements in VoIP technology, it is exciting to consider the possibilities of what the future may hold for this innovative field.
