This online article at Linux Journal explains how VoIP is being performed in a Linux lab using the soft switch and telephony hardware to improve sound quality. The article includes an overview of the basic concepts of IP telephony and its support under Linux. The authors write . . .

“Being able to integrate voice and data is a strong desire of business as well as of residential users. This type of integration is inefficient, however, on the telephone legacy of channelled voice slots having time division multiplexing (TDM) with expensive associated equipment. A data network like the Internet, with its statistical TDM, uses precious bandwidth much more efficiently. Moreover, the universal presence of IP both in wide area and local area networks makes it a convenient platform to launch VoIP traffic. In this article we share our experience of testing VoIP in our Linux lab. We discuss the entire VoIP environment, including the soft switch and the telephony hardware needed to improve voice quality . . .”
