Once a guest on telephone lines, the Net now threatens a takeover of its host's principal function: voice-to-voice communications. For intrabusiness use or as a public system, Internet-based telephony can be a real money-saver - or money-maker. In Voice Over IP Networks, you'll learn everything you need to: transmit real-time voices over the Internet; understand the technology and its costs; compare leading vendors and their Internet telephony products - 3Com, Motorola, Lucent, VocalTec, Vienna Systems, Nuera Communications, and more; evaluate advantages of the IPv6 and IPv4 protocols; use RSVP, RTSP, IP Multicast, SONET, ATM, and other technologies for telephony; apply Codecs to voice digitization; emulate T1/E1 trunks; implement a system with appropriate standards; and anticipate trends and new products from innovative companies such as QWest.
