VoIP Hacks: Tips & Tools for Internet
Telephony by Ted Wallingford
Very Very Highly Recommended!!
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, its 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 OReilly 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, youll 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.
Personal Review: VoIP Hacks: Tips & Tools for Internet
Telephony by Ted Wallingford
I've been in telephony and networking for nearly 30 years. Started in R&D
at a PBX manufacturer in 1979, then did a stretch with the, at that time,
worlds largest Ethernet company. Then I worked on a Fiber Optic Voice
and Data MAN (IEEE 802.6) and have been manufacturing telecom
products for the past 14 years. I think that gives me the qualifications to
critique this book even without having to mention the Ethernet board I
designed for IBM was featured on the cover of PC Week Magazine in
1987.
This is a very good book. If you are a VoIP systems integrator or do
anything with Asterisk, this book is a must have. There are major
problems with the current state of the VoIP industry. The two biggest
problems are security and the unavailability of a decent broadband
connection with QoS and an SLA below $400 per MegaBit. Yes $400, but
we're talking guaranteed availability and less than 0.5% packet loss,and
50mS or less latency with real penalties for not meeting the SLA.
Before reading this book I would not have considered putting an IP-PBX on
an ADSL link. The author's idea of putting a Sangoma ADLS modem in
the Linux box with PPPoE client software and controlling the modem
queue is nothing short of genius. Then to top it off with the AstShape QoS
scripts and the QoS monitoring tools, this book is an absolute bargain.
With these tools I'll not only know if the ADSL connection is capable of
supporting VoIP service, but I'll know exactly why. Much better than
cutting over to the VoIP system and later discovering the problems. The
whole book is just full of great ideas. There is something in this book for
everybody from the Skype user to a single VoIP phone owner, Asterisk, or
enterprise PBX administrators. Just check out the Table of Contents.
Amazon does not have the Table of Contents available but it is on the
O'Reilly website oreilly D0T C0M.
While the book is an asset for seasoned VoIP integrators, it is also a very
good resource for someone completely unfamiliar with VoIP with a desire
to learn. You can start out with free software for a Windows PC, progress
to purchasing a single VoIP phone, then to a Linux PC. If you are leary of
Linux, either get over it or you should probably stay out of VoIP altogether.
