Internet telephony

The Internet now handles extensive video, teleconferencing, fax, and voice communications, in addition to basic data transfer. But overlapping standards for mixed media transmissions can confuse even the most sophisticated engineers. Experienced telecom leader Uyless Black brings together all the tools and protocols for call proces sing in this single authoritative source.

Internet Telephony begms with an overview of basic telephony call processing, focusing on the différences between traditional circuit switching and the more contemporary packetbased networks. A special section discusses telephony routing over IR Along the way, Black explores the major standards and protocols in detail. Highlights include:

H.323: the ITU standard for transmitting mixed media signals via LANs and WANs
SIP: the IETFs Session Initiation Protocol used for IP teleconferencing
Megaco Protocol: a combined IETF/ITU standard for multimedia conferencing
MGCP: a call processing protocol, published as an informational RFC

For engincers, managers, or users, Internet Telephony is the one book to cover all the technologies.
