VocalTec Communications pioneers Voice over Internet Protocol (VoIP) technology, renowned for releasing the world's first commercial VoIP software, "Internet Phone," in 1995. The company's core offering allowed real-time voice communication over the internet, utilizing standard personal computers equipped with modems, sound cards, and microphones. VocalTec developed significant audio processing innovations, including a patented Audio Transceiver technology designed to manage jitter buffering, packet loss, and sample rate adjustments, ensuring low-latency voice transmission across packet-switched networks.
Founded in 1989 by Alon Cohen and Lior Haramaty, VocalTec emerged from their experience in the Israeli Defense Forces (IDF) telecommunications unit, where they honed expertise in packetized voice transmission for secure communications. This insight fueled their exploration into digital audio technologies. Cohen, with his electrical engineering background, served as the primary architect of core VoIP concepts, while Haramaty's software engineering acumen translated these ideas into practical implementations.
Initially, VocalTec's products served individuals seeking affordable international calls directly from their computers, effectively bypassing traditional telephone infrastructure. The company's long-term vision centered on revolutionizing global telecommunications by democratizing voice communication through the internet. VocalTec established the foundational principles for internet telephony, aiming to connect people worldwide with accessible and efficient digital voice services, fundamentally altering the landscape of communication.
