Overview

VocalTec Communications Inc. was an Israeli telecommunications technology company associated with the early development and commercialization of voice over Internet Protocol. Founded in 1985 by Alon Cohen and Lior Haramaty, the company began by creating audio hardware and speech technologies for personal computers. Its early work included the SpeechBoard sound card and text-to-speech systems in Hebrew and English, including tools intended to make computers more accessible to blind and visually impaired users. During the late 1980s and early 1990s, VocalTec developed a broad range of digital-audio products and applications. These included audio-editing tools, external and internal sound cards, automated telephone information systems, voice messaging over local networks, multimedia presentation tools, broadcasting systems, and specialized communications equipment. The company initially sold hardware, but management eventually shifted its emphasis toward software and network communications. That change produced VocalChat, a product for voice communication between computers over local and wide-area networks. The company later added Internet Protocol support and launched Internet Phone in February 1995. Internet Phone is widely recognized as one of the earliest, and often the first, commercially released VoIP applications for personal computers. Its underlying audio-transceiver technology was designed to manage the practical problems of packet-based voice communication, including jitter, packet loss, packet reordering, latency, and differences in sampling rates between endpoints. VocalTec's early Internet telephony technology helped establish the company as a significant participant in the emerging VoIP sector. It supplied technology to communications providers and worked with companies such as Deltathree. In 1997, Deutsche Telekom acquired a substantial minority stake and also agreed to purchase telecommunications products, services, and support. VocalTec also helped establish ITXC, a wholesale provider of Internet-based international calling whose network used VocalTec technology. The company completed an initial public offering on NASDAQ in February 1996. As the Internet and telecommunications markets expanded, VocalTec moved increasingly toward infrastructure for service providers rather than consumer software alone. In 2005 it completed a business combination with Tdsoft, a VoIP-gateway provider, and refocused on carrier-class multimedia and voice-over-IP systems. Its Essentra product family was presented as a modular foundation for next-generation communications networks, including trunking, peering, and residential and enterprise VoIP services. VocalTec's independent corporate history ended with a reverse takeover by magicJack on July 16, 2010. The VocalTec name is therefore principally remembered for its pioneering role in Internet telephony, its early VoIP patents and products, and its transition from PC audio tools to telecommunications infrastructure.

History

VocalTec was established in 1985 by Alon Cohen and Lior Haramaty, who had served together in the Israel Defense Forces. The company was formally incorporated in 1989. Its original mission was to create technologies that added speech and audio capabilities to personal computers and computer networks. Among its earliest products was SpeechBoard, a PC sound card sold primarily in Israel. VocalTec developed text-to-speech software for the product in both Hebrew and English. The work had an accessibility dimension: it enabled blind and visually impaired users to operate computers and, in some applications, communicate by telephone. Because Hebrew text-to-speech tools were not readily available at the time, the founders built the speech technology and language resources themselves, including a user-maintained pronunciation dictionary. The company experimented broadly with digital audio during the second half of the 1980s. Its projects included audio-editing software, a parallel-port audio device for laptop computers, digital playback equipment for mobile food vendors, multimedia presentation systems, voice-enabled telephone systems, radio-broadcast recording and transfer tools, automated interactive voice-response systems, and voice messaging over local networks. These projects gave VocalTec experience in both audio processing and practical communications applications. In 1990, technology entrepreneur Elon Ganor joined to lead international sales and marketing. He later became chief executive. VocalTec introduced The CAT, an audio peripheral for personal computers, to international markets in 1993, followed by CATBoard and other audio cards. Sales of those hardware products were modest, and company management concluded that future growth was more likely to come from software and network communications. VocalTec's strategic redirection accelerated in 1993. The company acquired ClassX, a development group led by Ofer Shem-Tov, and used the group as a foundation for software and network development. VocalChat was created to enable computer-to-computer voice communication over local and wide-area networks. Initially based on VocalTec's audio-transceiver work, the system was demonstrated at the Network InterOp trade show in Atlanta in May 1993. Internet Protocol support was added in 1994. In February 1995, VocalTec released Internet Phone. The application transmitted live voice over the public Internet and is commonly regarded as one of the first commercial VoIP applications. Its audio-transceiver design addressed problems that made real-time Internet voice difficult, including variable delay, jitter, packet loss, packet reordering, and mismatched transmitter and receiver sampling rates. The launch attracted substantial attention because it demonstrated that ordinary personal computers could be used for Internet calling. VocalTec went public on NASDAQ in February 1996. The company then pursued partnerships and infrastructure opportunities as Internet telephony moved from experimentation toward commercial deployment. In 1997, Deltathree launched an international low-cost calling service using VocalTec technology. VocalTec also helped establish ITXC, a wholesale Internet voice carrier led by Tom Evslin. ITXC grew into a major VoIP carrier before being acquired by Teleglobe in 2003. Deutsche Telekom became an important strategic customer and investor. In 1997 it acquired a 21.1 percent stake in VocalTec and agreed to purchase additional telephony products, services, and support. This relationship reflected VocalTec's evolution from a maker of PC software into a supplier to established telecommunications operators. In 2005, VocalTec completed a business combination with Tdsoft, a provider of VoIP gateways. The combined strategy emphasized carrier-class multimedia and voice-over-IP systems. VocalTec's Essentra suite was positioned as a set of building blocks for next-generation networks, supporting applications such as trunking, peering, residential VoIP, and enterprise communications. The company was ultimately absorbed through a reverse takeover by magicJack on July 16, 2010. VocalTec's corporate history therefore spans three phases: experimental and accessible PC audio, pioneering consumer Internet telephony, and carrier-oriented VoIP infrastructure. Its enduring historical significance comes from helping turn voice communication over packet networks into a usable commercial product.
