Download or read book Switching to VoIP written by Theodore Wallingford and published by "O'Reilly Media, Inc.". This book was released on 2005 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowersbusinesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O'Reilly's Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you're a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You'lldiscover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directoryservices retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium.You'll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls. It's the only thing left between you and a modern telecom network.

Book excerpt: Fed up with the high tolls charged by your ordinary telephone service? If you're itching to cut the copper cord with your costly, traditional phone service, you need Talk is Cheap, the new, easy-to-understand guide to understanding and using Voice over Internet Protocol (VoIP) and other Internet telephone options.Technologies such as VoIP are gaining a great deal of attention these days as more people switch from standard telephone service to phone service via the Internet. But while the cost savings are outstanding, there are some issues with Internet telephony that you should know about. Are the connections reliable? Is the quality comparable? Will it include 911 services?James Gaskin's Talk is Cheap addresses these issues and many more by explaining how to make the switch and what the tradeoffs will be if you opt for Internet telephony over traditional phone services.Talk is Cheap focuses on the increasingly popular services from Vonage, which uses VoIP, and Skype--a free service that operates as a peer-to-peer (P2P) network with the ability to turn any PC, Mac, or Pocket PC into a telephone. The book explains your options; explores the background behind, the workings of, and differences between VoIP and P2P networks; and discusses the advantages and drawbacks of both technologies (including service offerings, quality, capabilities, completion rates, and more).Talk is Cheap then goes into detail on what you can expect in Internet service from traditional phone companies such as Verizon and AT&T. In addition, you will learn more advanced techniques, including how to turn your Palm or Pocket PC into an Internet phone and how to work with Wi-Fi phones and videophones.A straightforward, quick introduction to the ins and outs of using Internet telephone services, this book provides everything you need to make informed telephone decisions--whether you're thinking about the switch from traditional phone service or have already made it and want to get the most out of your new Internet telephone.

Available in PDF, EPUB and Kindle. Book excerpt: What most of us know as "the Internet" is actually a set of largely autonomous, loosely coordinated communication networks. As the influence of the Internet continues to grow, understanding its real nature is imperative to acting on a wide range of policy issues. This timely new book explains basic design choices that underlie the Internet's success, identifies key trends in the evolution of the Internet, evaluates current and prospective technical, operational, and management challenges, and explores the resulting implications for decision makers. The committee-composed of distinguished leaders from both the corporate and academic community-makes recommendations aimed at policy makers, industry, and researchers, going on to discuss a variety of issues: How the Internet's constituent parts are interlinked, and how economic and technical factors make maintaining the Internet's seamless appearance complicated. How the Internet faces scaling challenges as it grows to meet the demands of users in the future. Tensions inherent between open innovation on the Internet and the ability of innovators to capture the commercial value of their breakthroughs. Regulatory issues posed by the Internet's entry into other sectors, such as telephony.
