The key source for the principal Internet telephony services and standards.

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 processing in this single authoritative source.

Internet Telephony begins with an overview of basic telephony call processing, focussing on the differences between traditional circuit switching and the more contemporary packet-based networks. A special section discusses telephony routing over IP. 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 IETF's 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 engineers, managers, or users, Internet Telephony is the one book to cover all the technologies.
