| This bestselling book is now the standard guide to building
phone systems with Asterisk, the open source IP PBX that has
traditional telephony providers running scared! Revised for
the 1.4 release of the software, the new edition of
Asterisk: The Future of Telephony reveals how you can save
money on equipment and support, and finally be in control of
your telephone system.
If you've worked with telephony in the past, you're familiar
with the problem: expensive and inflexible systems that are
tuned to the vendor's needs, not yours. Asterisk isn't just
a candle in the darkness, it's a whole fireworks show.
Because Asterisk is so powerful, configuring it can seem
tricky and difficult. This book steps you through the
process of installing, configuring, and integrating Asterisk
with your existing phone system.
You'll learn how to write dialplans, set up applications
including speech synthesis and voice recognition, how to
script Asterisk, and much more -- everything you need to
design a simple but complete system with little or no
Asterisk experience, and no more than rudimentary
telecommunications knowledge. The book includes:
A new chapter on managing/administering your Asterisk system
A new chapter on using Asterisk with databases
Coverage of features in Asterisk 1.4
A new appendix on dialplan functions
A simplified installation chapter
New simplified SIP configuration, including examples for
several popular SIP clients (soft phones and IP telephones)
Revised chapters and appendicies reviewed and updated for
the latest in features, applications, trends and
best-practices
Asterisk is revolutionizing the telecom industry, due in
large part to the way it gets along with other network
applications. While other PBXs are fighting their inevitable
absorption into the network, Asterisk embraces it. If you
need to take control of your telephony systems, move to
Asterisk and see what the future of telecommunications looks
like.
