Book About Phone Equipment Warns Buyers That They Probably Need More Than The Sellers Want To Sell

VoIP Monitor — Fri, 27 Feb 2009 18:33:56 GMT

During tough economic times, the desire to buy at the lowest possible price creates pressure to sell at the lowest possible price; but low prices can actually hurt the buyer.

"Phone Systems & Phones for Small Business & Home" by Michael N. Marcus.

According to Michael N. Marcus, author of "Phone Systems & Phones for Small Business & Home," the lowest price is probably not the best deal.

"Because of intense competition and pressure to minimize the price on a proposal or bid," Marcus said, "salespeople are often afraid to suggest a phone system that might cost even $20 more than a competitor's system. Unfortunately, salespeople may try to sell systems that are too small, or they leave out important items. Some 'options' should really be considered necessities."

The authoritative but easy-to-understand new book explains what goes into a phone system, and how to choose the right size that will minimize initial cost yet still allow for economical expansion. It describes and evaluates types of phones and systems, and has an extensive chapter explaining what some phone system salespeople may not want buyers to know.

There have been major changes in every aspect of telecommunications.

A hundred years ago, telephones were simple. If you wanted to call someone, you picked up the receiver, cranked the crank, and waited for a nice lady to say, "Operator, may I help you?" Then you said something like, "I want to talk to Daddy," or "I need the doctor;" and in a few seconds you were connected. You didn't even need to know the phone numbers.

For equipment, maybe you could choose an oak box on the kitchen wall or a metal candlestick model on the hall table. If you lived in a high-tech area, maybe you could get a dial instead of a crank.

Regardless of the telephone style, you would pay to rent it month after month, and there was usually just one company in your town that you could do business with, and that company owned "your" phone.

Today the choices seem endless. Phones can be analog or digital, rotary or touch-tone, plain or fancy, corded, cordless or cellular. You can connect through a local phone company, a national phone company, an international phone company, a TV company, a satellite company, a cellular company, or a VoIP company. Phone companies sell TV service. Cable television companies sell phone service. They both sell Internet service.

You can get a phone or phone system or a phone gadget from hundreds of sources, and buy it, rent it, lease it or maybe get it for free. You can pay someone to install it, you can install it yourself, or you can get something that needs no installation.

Marcus helps people sort out their options. The book covers basic phones, multi-line phone systems, add-ons like headsets, music-on-hold, paging systems, backup power and fax equipment -- for professional offices, businesses and homes. There are sections on technology trends, tools, wiring, troubleshooting, and much more.

The book, which should be helpful for both buyers and sellers, also sorts out the various technologies for making phone calls and accessing the Internet -- conventional dial tone, ISDN, DSL, cable, fiber, wireless, T1 and VoIP. It has detailed information about plugs and jacks, explains the difference between wire and cable, and tells readers how to find their octothorpe.

There's even a section that explains why touch-tone pads have 1-2-3 on the top, but computers and calculators have 1-2-3 on the bottom. Funny chapters discuss "technology for women," and how actor Stephen Baldwin and motorcycle maker Paul Teutul, Sr. waste time on the telephone. A very serious chapter warns about the danger of inadequate protection against electrical surges.

Other parts of the book explain the break-up and apparent re-formation of the Bell System, why GTE phones were heavier and uglier than AT&T phones, and the difference between a hookswitch and a switchhook. Readers will even learn who really makes phones that carry the AT&T label, about the disastrous deal between Lucent and Philips, why phone renting is a terrible deal for the renter, and why "broadband" is not the same thing as "high speed."

Reference material includes 37 pages on telecommunications terminology, an extensive chapter on acronyms, and illustrations of "weirdo" phone plugs. The chapter with important telephone numbers includes a number people can call to identify the number they're calling from, and a number for tracing threatening or nuisance phone calls.

The chapter on cordless phones explains how actress Hedy Lamarr co-invented vital technology during World War 2 that later was used by the U.S. military in the Viet Nam War and the blockade of Cuba, and is now used in millions of phones.

Marcus's book includes about 40 detailed hands-on product reviews. Recommendations range from a $12.99 home phone to complex multi-thousand-dollar business phone systems, plus a wide array of add-ons to improve communications.

It will help readers avoid the worst mistakes of phone system buyers, and can help them decide if they can save money by installing their own home or business phones. The book will also help people quickly diagnose many common telecom troubles, and often fix them easily and inexpensively or maybe even for free.

Marcus says, "But even if you don't plan to do your own phone work, by understanding what has to be done, you're more likely to get the right thing done, and pay the right price. You could save much more than the price of this book."

Some reader comments:

"Outstanding! An entertaining and sometimes humorous thorough education on phones and telecommunications. It's a must-read for shoppers as well as salespeople."

"I've been in telecommunications for nearly 30 years, but I still learned a lot from this informative and entertaining book."

"After just three minutes I learned that a really annoying telephone problem could be cured for $4, instead of nearly $400. This book belongs in every office and many homes."

"This delightful book makes phones ultra-useful for people who run mini-Fortune 500 companies. Highly recommended."

The illustrated book has 396 pages.

Switching to VoIP

by Theodore Wallingford

Book Description

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 anddata 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 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 ofthe 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 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, IP Tables 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.

Asterisk: The Future of Telephony

by Jim Van Meggelen

Book Description >

It may be a while before Internet telephony with VoIP (Voice over Internet Protocol) reaches critical mass, but there's already tremendous movement in that direction. A lot of organizations are not only attracted to VoIP's promise of cost savings, but its ability to move data, images, and voice traffic over the same connection. Think of it: a single Internet phone call can take information sharing to a whole new level.

That's why many IT administrators and developers are actively looking to set up VoIP-based private telephone switching systems within the enterprise. The efficiency that network users can reach with it is almost mind-boggling. And cheap, if the system is built with open source software like Asterisk. There are commercial VoIP options out there, but many are expensive systems running old, complicated code on obsolete hardware. Asterisk runs on Linux and can interoperate with almost all standards-based telephony equipment. And you can program it to your liking.

Asterisk's flexibility comes at a price, however: it's not a simple system to learn, and the documentation is lacking. Asterisk: The Future of Telephony solves that problem by offering a complete roadmap for installing, configuring, and integrating Asterisk with existing phone systems. Our guide walks you through a basic dial plan step by step, and gives you enough working knowledge to set up a simple but complete system.

What you end up with is largely up to you. Asterisk embraces the concept of standards-compliance, but also gives you freedom to choose how to implement your system. Asterisk: The Future of Telephony outlines all the options, and shows you how to set up voicemail services, call conferencing, interactive voice response, call waiting, caller ID, and more. You'll also learn how Asterisk merges voice and data traffic seamlessly across disparate networks. And you won't need additional hardware. For interconnection with digital and analog telephone equipment, Asterisk supports a number of hardware devices.

Ready for the future of telephony? We'll help you hook it up.

IP Telephony - The Integration of Robust VoIP Services

by Bill Douskalis

From the Inside Flap

Introduction:

In the last five years of the twentieth century, we have seen developments in the telephone network which will affect our lives well into the new millennium. A continuing and massive effort by the industry is bringing closer the day when integrated services and multimedia will finally come to our homes-on demand and at affordable prices. The Plain Old Telephone Service, POTS as it has been known for most of the twentieth century, is giving way to modernization, service integration, and convergence of two fundamentally different types of technologies: voice and data.

There is nothing wrong with the quality of the Public Switched Telephone Network, the PSTN as we have known it for so many years, either in the delivered speech quality or in its reliability. On the contrary, it is the model of robustness and security, and those of us who know its intricate details are amazed by how something this large and this complex can function so reliably and so well. But the quality of a telephone conversation seems to have given way to other, higher priorities and is no longer the only driving factor for modernizing the network. Changing needs in both the business and residential market segments require new telephony features and capabilities that are neither simple nor economical for service providers to create on top of the PSTN infrastructure. This contrasts the current fact of life of the telephone companies, which are approaching the point of not being able to produce a single new feature in their present networks without substantial expenditures and delays. Service and feature creation on standard Class 5 service platforms became simply an intractable and very expensive proposition. So, when the requirements of the market aligned with the needs of the service providers, it was only a matter of a short time before it became obvious the PSTN had to be transformed and modernized, not in an evolutionary manner but in a revolutionary manner. But is the new PSTN that is coming our way going to be better? And who defines what better is? And who will pay for all this modernization? There are both simple and complex answers for these three questions.

VoIP Hacks

by Ted Wallingford

Book Description:

Voice over Internet Protocol (VoIP) is gaining a lot of attention these days, as more companies and individuals switch from standard telephone service to phone service via the Internet. The reason is simple: A single network to carry voice and data is easier to scale, maintain, and administer. As an added bonus, it's also cheaper, because VoIP is free of the endless government regulations and tariffs imposed upon phone companies.

VoIP is simply overflowing with hack potential, and VoIP Hacks is the practical guide from O'Reilly that presents these possibilities to you. It provides dozens of hands-on projects for building a VoIP network, showing you how to tweak and customize a multitude of exciting things to get the job done. Along the way, you'll also learn which standards and practices work best for your particular environment. Among the quick and clever solutions showcased in the book are those for:

gauging VoIP readiness on an enterprise network
using SIP, H.323, and other signaling specifications
providing low-layer security in a VoIP environment
employing IP hardphones, analog telephone adapters, and softPBX servers
dealing with and avoiding the most common VoIP deployment mistakes

In reality, VoIP Hacks contains only a small subset of VoIP knowledge-enough to serve as an introduction to the world of VoIP and teach you how to use it to save money, be more productive, or just impress your friends. If you love to tinker and optimize, this is the one technology, and the one book, you must investigate.

SIP Beyond VoIP

by Henry Sinnreich, Alan B. Johnston, Robert J. Sparks, Vinton G. Cerf

Book Description:

VON Publishing's latest effort is SIP Beyond VoIP, an extraordinary 333-page effort that picks up where previous books have left off about SIP (Session Initiation Protocol), the protocol that has revolutionized the world of VoIP. The book's three distinguished authors relate in great detail how this versatile and extensible protocol has truly moved beyond VoIP and is now starting to have an impact on the whole telecommunication industry, including wireless and enterprise communications.

Anyone who thinks that SIP has any real competitors will come away from this book in astonishment. SIP-Events are the glue that even now integrates communications and applications. And SIP-Presence may well be the dial tone of the 21st century.

The book's advanced discussion of SIP interleaves with such associated topics as DNS (the Domain Name Service), ENUM (electronic numbering), NAT (Network Address Translation) and firewall traversal, security, Peer-to-Peer SIP (P2P SIP) networks, SIP-based conferencing/collaboration and even accessibility to communications for disabled people.

This heavily illustrated, footnoted and fully-indexed book also has a foreword by Vinton Cerf, who writes: It is my honest opinion that we have barely scratched the surface of the various applications to which SIP may be adapted. If we have seen 1% of the applications of SIP so far, then there are still 99% waiting to be invented, developed or deployed. The generality of SIP will make it a major workhorse the Internet of this century.

If you think you know SIP, think again. Get this book, its authors will set you straight about SIP, once and for all!

Practical VoIP Using VOCAL

by Luan Dang, Cullen Jennings, David G Kelly

Book Description:

While many books describe the theory behind Voice over IP, only Practical VoIP Using VOCAL describes how such a phone system was actually built, and how you too can acquire the source code, install it onto a system, connect phones, and make calls.

VOCAL (the Vovida Open Communication Application Library) is an open source software project that provides call control, routing, media, policy, billing information and provisioning on a system that can range from a single box in a lab with a few test phones to a large, multi-host carrier grade network supporting hundreds of thousands of users. VOCAL is freely available from the Cisco Systems-sponsored Vovida.org community web site (http://www.vovida.org/).

A Silicon Valley start-up called Vovida Networks, Inc (think of VOice, VIdeo, DAta) created VOCAL and invested over one hundred man years into its development. Since Cisco acquired Vovida in 2000, individuals representing every significant telecom company and service provider in the world have downloaded the source code. Today, more and more people are successfully building VOCAL into professional solutions, while contributing fixes and new functionality back to Vovida.org.

Because VOCAL is open source, you can look "under the hood" to the base code and protocol stack levels and discover not only how the system works, but also how common problems are being worked out in the development environment. We're hoping that you will be inspired to take this system to another level by implementing a feature or functionality that no one has thought of before.

Written by a team from Vovida Networks, Practical VoIP Using VOCAL includes the following topics:

Installing and configuring VOCAL 1.4.0 onto a single host and onto a multi-host network with phones and gateways
C++, C and Java architecture found within VOCAL
Provisioning a VoIP system
SIP (Session Initiation Protocol), SDP (Session Description Protocol) and RTP (Real-time Transport Protocol) for call control and media
TRIP (Telephony Routing over IP), DNS SRV and ENUM for routing
MGCP (Media Gateway Control Protocol) and H.323 for call control and translation into SIP
COPS (Common Open Policy Service), OSP (Open Settlement Protocol) and RSVP (Reservation Protocol) for policy and Quality of Service
RADIUS (Remote Authentication Dial In User Service) for interfacing with billing servers
SNMP (Simple Network Management Protocol)

If you're interested in VoIP, this is the only book available that focuses on the real issues facing programmers and administrators who need to work with these technologies.

Book Info

Voice Over IPv6

by Daniel Minoli

Book Description

IPv6 (Internet Protocol version 6) is the future of internet telephony. And this book is your guide to that future.

IPv6 is the replacement for the currently used IPv4 (Internet Protocol version 4). IPv6 will offer increased IP addresses (full 128-bit addresses, compared to the 32-bit addresses of IPv4), enhanced security, and greater robustness. It will also be fully backwards compatible with existing IPv4 systems. These capabilities will finally make internet telephony a viable competitor to conventional switched telephone networks. In this book, Dan Minoli clearly explains IPv6 and how telephone networks can be built on its foundations.

This is not just another IPv6 book; instead, it focuses on those aspects of IPv6 relevant to internet telephony systems and voice networks. Minoli uses a compare/contrast approach, exploring where IPv6 is similar to IPv4 and where it differs, to let you quickly grasp the essence of IPv6 and the similarities (and differences) between current IPv4-based systems and IPv6-based systems.

If you will be designing, implementing, or maintaining the next generation of internet telephony systems, then you need the information in this book!

*Explains the essential concepts of IPv6 and how they relate to internet telephony
*Describes how internet telephony systems using IPv6 are different fromand better thaninternet telephony systems based on the older IPv4 standard
*Discusses how to transition existing IPv4 internet telephony systems and conventional switched systems to IPv6-based systems
*Extensive treatment of security issues, including IP layer encryption and authentication methods
*Explains connection techniquesincluding plug and play approachesfor equipment used in IPv6 systems

* The first title describing how the next generation internet protocolIPv6can be used for internet telephony.
