O'Reilly Released VoIP Hacks

Voice over IP, or VoIP, may be the most important IP technology to emerge in the last year or two. VoIP is a family of technologies that enables voice applications and telephony to be carried over an IP network such as the Internet. These technologies include protocols, hardware and software standards, and computer programs. VoIP is employed in telephony applications, from analog phones to next-generation IP phones and wireless headsets, and in desktop voice chat services, from web-based party-line chat services (like Yahoo Chat) to the well-known Skype desktop voice-calling service.
