Switching to VoIP

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 empowers businesses 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’ll discover 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 directory services
  • 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.

Beginning Oracle Database 11g Administration: From Novice to

This book, written by veteran Oracle database administrator Iggy Fernandez, a regular on the Oracle conference circuit and the editor of NoCOUG Journal, is a manageable introduction to key Oracle database administration topics including planning, installation, monitoring, troubleshooting, maintenance, and backups, to name just a few. As is clear from the table of contents, this book is not simply a recitation of Oracle Database features such as what you find in the reference guides available for free download on the Oracle web site. For example, the chapter on database monitoring explains how to monitor database availability, database changes, database security, database backups, database growth, database workload, database performance, and database capacity.

The chapters of this book are logically organized into four parts that closely track the way your database administration career will naturally evolve. Part 1 gives you necessary background in relational database theory and Oracle Database concepts, Part 2 teaches you how to implement an Oracle database correctly, Part 3 exposes you to the daily routine of a database administrator, and Part 4 introduces you to the fine art of performance tuning. Each chapter has exercises designed to help you apply the lessons of the chapter. Each chapter also includes a list of reference works that contain more information on the topic of the chapter.

In this book, you’ll find information that you won’t find in other books on Oracle Database. Here you’ll discover not only technical information, but also guidance on work practices that are as vital to your success as technical skills. The author’s favorite chapter is “The Big Picture and the Ten Deliverables.” If you take the lessons in that chapter to heart, you can quickly become a much better Oracle database administrator than you ever thought possible.

What you’ll learn
  • Theory of relational database management systems
  • Oracle Database internals
  • Licensing, architecture, and sizing
  • Software installation and database creation
  • Using indexes to improve performance
  • User management and data loading
  • How to monitor all aspects of your database
  • How to solve and fix problems
  • Database backups and database recovery
  • Database maintenance
  • Database tuning
  • SQL tuning
Who this book is for

If you are an IT professional who has been thrust into an Oracle database administration role without the benefit of formal training, or you just want to understand how Oracle Database works, this book is for you. It’s the book the author wishes he’d had when he first started using Oracle Database many years ago. It’s the book that he would have liked to have given to the many IT colleagues and friends who, over the years, have asked him to teach them the basics of Oracle Database.
