Publisher Summary This chapter discusses how voice data is converted into digital traffic and transmitted from one point to another. Salient to this process is an understanding of the difficulties that Voice over Internet Protocol (VoIP) designers and implementers have to contend with, including timing jitter, timing latency, processing, and ...

The 1974 origins of VoIP [PDF]
IEEE Signal Processing Magazine, 2005 This paper brings light on the digital signal processing (DSP) roots of a modern concept, voice over IP (VoIP). An example is also provided in which developments in DSP - speech coding, in particular - had a profound impact on the early development of the ARPANET, the ancestor of the Internet.

VoIP has been found to be capable of delivering effective voice calls. However, current solutions require careful network engineering at present to provide sustained voice quality. With a number of large players very active in the development of equipment, the performance of the technology continues to improve rapidly and unit costs continue to decline.

, 2012 We present the analysis and design of a Small World VoIP system (SW-VoIP) which is geared towards customers that are communicating with their Small World of social contacts. We use the term Small World to refer to the Peer-to-Peer (P2P) network of a client and his contacts both incoming and outbound.

Internet Telephony market is glowing very rapidly both in the international and domestic telecommunication markets. It is expected that the traffic of the global Internet telephony will exceed that of international legacy telephone traffic in around 2005. Currently, QoS of Internet telephony is not guaranteed nor specified.
