""Focused on why the reader should care about a particular technology, and what the reader can gain from it." -- Steven Shepard, author of "Telecommunications Convergence, now in its Second Edition IS INTERNET TELEPHONY FOR YOU? IF SO, HOW? ANSWERS HERE With a potential 90 percent reduction in phone costs, voice over data networks could offer your business substantial benefits. But how do you know if telephone over IP (Internet Protocol) suits your needs and setup? And if it does, what will it take to make it work? If you want straightforward answers to these questions, you've come to the right place. Lighting the way to IP telephony is Ken Camp's specialty, and in IP Telephony Demystified he offers the best set of tools out there for making basic get-going decisions. You must read this book if-- * you're on IT staff or in management of a small business and investigating voice over data lines * escaping from the telephone companies' clutches sounds appealing * the economies of voice and data on the same network are obvious * the no-go or go decision on IP telephony is your assignment * what's-in-it-for-my-company questions are uppermost in your mind * direct, measurable benefits is an important item in your agenda * choosing the right protocol might be a job-saver * before wrestling SIP, H.323, or Megaco/H.248, you want to know if the match is worth the prize * practical how-to's on integrating voice into your LAN could reduce your workload * you'd rather have quality-of-service (QoS) answers--on IntServ, Diff Serv, and MPLS--than quality-of-service concerns * a 3D view of cost and service implications is what you seek IP telephony is simplyvoice sent over an IP network like the Internet. It can mean enormous savings--but not for every business. This is the book that will clarify whether it's right for your company, and if so, how to make it work.

Open settlement protocol - OSP is a client/server protocol that Internet service providers use to exchange authorization, accounting, and usage information to support IP telephony. OSP is defined by ETSI (European Telecommunications Standards Institute) Project TIPHON (and Internet Protocol Harmonization Over Networks).

Internet Protocol Control Protocol - In computer networking, Internet Protocol Control Protocol (IPCP) is an network control protocol for establishing and configuring Internet Protocol over a Point-to-Point Protocol link. IPCP uses the same packet exchange machanism as the Link Control Protocol.

Internet protocol suite - The Internet Protocol Suite is the set of communications protocols that implement the protocol stack on which the Internet and most commercial networks run. It is sometimes called the TCP/IP protocol suite, after the two most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were also the first two defined.

Internet Message Access Protocol - The Internet Message Access Protocol (commonly known as IMAP, and previously called Interactive Mail Access Protocol) is an application layer Internet protocol used for accessing email on a remote server from a local client. IMAP and POP3 (Post Office Protocol version 3) are the two most prevalent Internet standard protocols for email retrieval.
