商品描述

“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

* whats-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-tos on integrating voice into your LAN could reduce your workload

* youd 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 simply voice 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 its right for your company, and if so, how to make it work.

商品描述(中文翻譯)

「專注於讓讀者關心特定技術的原因,以及讀者可以從中獲得什麼好處。」- Steven Shepard,《電信融合》作者,現已出版第二版。

互聯網電話適合您嗎?如果是的話,該如何使用?這裡有答案。

通過數據網絡進行語音通信可能為您的業務帶來巨大的好處,可將電話費用降低90%。但是,您如何知道互聯網協議(IP)電話是否適合您的需求和設置?如果適合,又需要什麼條件才能使其運作?如果您想要直接的答案,那麼您來對地方了。Ken Camp是IP電話的專家,他在《IP電話解密》一書中提供了最好的工具,以便做出基本的決策。

如果您符合以下情況,您必須閱讀本書:

- 您是IT人員或小型企業的管理人員,正在研究數據線上的語音通信。
- 想要擺脫電信公司的束縛聽起來很有吸引力。
- 語音和數據在同一網絡上的經濟效益是明顯的。
- IP電話的可行性是您的任務。
- 公司的利益是您最關心的問題。
- 直接、可衡量的好處是您議程中的重要項目。
- 選擇正確的協議可能是節省工作的關鍵。
- 在使用SIP、H.323或Megaco/H.248之前,您想知道是否值得進行。
- 關於將語音整合到您的局域網中的實際操作方法可能會減輕您的工作量。
- 您更希望得到有關服務質量(QoS)的答案,而不是擔心服務質量。
- 您正在尋找成本和服務影響的三維視圖。

IP電話只是通過像互聯網這樣的IP網絡傳送的語音。這可能意味著巨大的節省,但並非適用於每個企業。這本書將澄清它是否適合您的公司,如果是的話,如何使其運作。
