VocalTec Pioneers Internet Phone Technology

VocalTec was founded in 1991 by Yoel Zanger, a computer science student at the Hebrew University of Jerusalem.

The company's early success was fueled by the growing demand for internet-based communication solutions.

VocalTec's first product, Internet Phone, was released in 1995 and allowed users to make voice calls over the internet using a dial-up modem.

This innovation paved the way for modern VoIP (Voice over Internet Protocol) technology.

VocalTec released the first ever Internet VoIP application in February 1995, called Internet Phone, which was the world's first VoIP software.

The software was invented by Alon Cohen and Lior Haramaty, the two co-founders of VocalTec Ltd. They based their product on the invention of the "Audio Transceiver", which managed dynamic jitter buffer and achieved adaptive lower possible audio latency.

In 1997, Deltathree launched an Internet-based international low cost calling service using VocalTec's VoIP technology, and VocalTec Internet Phone "PC to Phone" system.

VocalTec's share peaked at a price of $3,363 per share on March 3, 2000, during the Dot-com bubble.

The company completed a business combination with Tdsoft in 2005, refocusing on providing carrier-class multimedia and voice-over-IP systems for communication service providers.

Vocaltec Internet Phone was the first software to permit voice over IP, making communication beyond traditional phone calls possible.

The service was designed by Alon Cohen and Lior Haramaty, founders of the Israeli company Vocaltec in 1989, which was unusual to find such developments outside of Silicon Valley at the time.

Alan Cohen invented the Audio Transceiver, which allowed digitalized voice to be transmitted acceptably, overcoming packet loss and latency present in connections of the era.

The Vocaltec Internet Phone had limitations, including the need for a sound card to emulate traditional calls, with half-duplex sound cards only allowing walkie-talkie style conversations and full-duplex cards required for simultaneous conversations.

The service wasn't "free", with a $70 registration fee for unlimited calls, making solutions like Skype and MSN revolutionary for providing unlimited communication without borders.

The Internet Phone was a game-changer in the world of communication, and it's hard to believe it was first released in 1995 by VocalTec.

VocalTec Internet Phone was the world's first VoIP software, and it was invented by Alon Cohen and Lior Haramaty, the co-founders of VocalTec Ltd. The software was named Internet Phone, but many people simply called it iPhone, which is where the name of the popular smartphone comes from.

The Internet Phone was based on the invention of the "Audio Transceiver", which managed the dynamic jitter buffer that was critical for achieving adaptive lower possible audio latency. This was a crucial feature that allowed the software to handle packet loss, packet re-ordering, and receiver transmitter sample rate adjustments.

In 1995, the Internet Phone was still a relatively new concept, and it required a computer with a sound card to work. The limit was that only half-duplex sound cards were available, which meant that conversations were like walkie-talkies.
