Über den Autor und weitere Mitwirkende
Leif Madsen first took an interest in Asterisk while attempting to find a voice conferencing solution for him and his friends. After someone suggested trying Asterisk, the obsession began. Wanting to contribute and be involved with the community, and noticing the lack of Asterisk documentation, he co-founded the Asterisk Documentation Project. Leif is currently working as a consultant, specializing in Asterisk clustering and call-centre integration. You can get more information at http://www.leifmadsen.com. Jim Van Meggelen is a founding partner of Core Telecom Innovations, a Canadian-based provider of open-source telephony solutions. He has over twenty years of enterprise telecom experience, for such companies as Nortel, Williams and Telus, and has has extensive knowledge of both legacy and VoIP equipment from manufacturers such as Nortel, Cisco and Avaya. Jim was the architect of two of the world's largest managed enterprise voice networks; each solution serving roughly twenty-thousand users in more than one-thousand communities across Canada, providing telecommunications in five different languages, through six time zones, administered completely from a central location. These networks pioneered the use of extensive automation and database control in a branch voice network - functionalities not generally available in proprietary telecommunications systems. Jim has now moved on from the world of proprietary telecom, and is commited to open-source telephony. Jim is one of the principal contributors to the Asterisk Documentation Project, and is co-author of the bestselling O'Reilly book, Asterisk: The Future of Telephony. He enjoys teaching, public speaking, improvisational acting, and writing. Jim lives in Toronto. Russell is the Engineering Manager for the Open Source Software team at Digium, Inc. He has been a core member of the Asterisk development team since the Fall of 2004. At the first AstriCon in 2004, he was named the release maintainer for Asterisk's first major release series, Asterisk 1.0. He has since contributed to almost all areas of Asterisk development, from project management to core architectural design and development. Russell received a bachelor's degree in Computer Engineering from Clemson University in the Fall of 2006. He is currently working on a master's degree in Software Engineering at the University of Alabama in Huntsville.

Originally called "Asterisk, The Future of Telephony", the new title is more apropos. Not only is "the future of telephony" a present-day reality, but all earlier editions have been the de-facto definitive guides as well. The third edition welcomes contributions from the brilliant Russell Bryant.
Our venture capital fund uses Asterisk to bring competitive advantages to our our portfolio companies. I use Asterisk personally to build "crazy powerful" and fun telephony solutions for myself and family. With the stunning power and versatility of Asterisk, it's no wonder there are more Asterisk servers running than all the Google and Facebook servers in the world!
While the preface indicates that the book takes a gentle approach to the Asterisk novice, the experience will be better if the reader is familiar with telephony terminology at a basic level. Basic Linux sysadmin skills are assumed, with CentOS and Ubuntu used for the example installations.
After a short history of Asterisk and its ecosystem, the book moves on to fairly detailed installation and configuration on a "clean" server. The approach used is retrieve source code from the Subversion repository and compile, rather than rely on (probably) outdated system packages.
Subsequent chapters cover Asterisk configuration options in detail, with all the primary areas of interest represented, starting with dialplan basics, voicemail, fax, etc.
A feature which I appreciated was the use of visually distinct sections, set off by a "bear trap" icon, to warn of pitfalls that commonly ensnare users or administrators, e.g., internet access is required when running the "make install" command for DAHDI, as this will try to download drivers from the Digium site. Trivial for home users, frustrating for corporate admins running the install in a disconnected lab if an unexpected failure occurs.
Recommended addition to the bookshelf of any sysadmin dealing with Asterisk and / or telephony in general.
Disclaimer, I was provided access by O'Reilly Publishing to a digital copy of this book for review purposes.
I'm a director of I.T. in a small company. Asterisk is only 1 part of all that I'm responsible for. However, whenever a telephony issue comes up or a new phone request from users surfaces, I'm almost always able to quickly solve it through help from this book.
I've also been able to suggest new ways of doing business in our company from reading this book. Asterisk is so full of features that it was worth reading cover-to-cover in order to have in mind what solutions were possible. As a result, when a business question arose regarding telephony, I'd immediately be able to recall how Asterisk could help. I'd then be able to quickly see how it's done by referring back to this book.
This book is not only useful, but I'd dare say required for anyone contemplating or already using Asterisk.
