If you can send data over the internet, why not voice, and if voice, why not phone calls, and if phone calls, why not video phone calls. This program looks at the new technology of internet telephony or voice over IP (VOIP) and video telephony. Demonstrations include PowWow 3.7, Tribal.com, ClassPoint 1.02, Connectix QuickCam 1.0, Logitech's QuickClip, Best Data Smart One, and ClearPhone. Originally broadcast in 1999. Copyright 1999 Stewart Cheifet Productions.

Voice over Internet Protocol (VoIP) is growing in popularity in the civilian and military communities due to its low cost and the management advantages it offers over traditional Public Switched Telephone Networks (PSTN) phone systems. Many military commands do not have the infrastructure or funding that is required to support the rapid expansion of multiple phone services at various locations throughout the world. VoIP offers a rapidly deployable alternative. A subjective study was designed to...

After its introduction in mid 90s, Voice Over Internet Protocol (VoIP) or IP telephony has drawn much attention. The prospect of cost savings on long distance and international toll calls, the global presence of Internet Protocol (IP), and the trend to converge data networks with voice networks have made VoIP one of the fastest growing telecom sectors. Additionally, the emergence of 3rd Generation (3G) cellular technology which offers high bandwidth will result in the convergence of the...
