Asterisk scales up and down from individual lines to vast multiserver installations across multiple continents, but the way to start is to install the package, open up some of the configuration files, and start looking at examples.
He is the author of several books and many open-source projects. Click here to read a sample chapter. Please enjoy Chapter 8, Optimizing Server Settings. He speaks frequently on system performance, open source, DevOps, and team optimization at universities, major companies, and industry conferences.
The creation and growth of Asterisk were the inescapable results of the convergence of the four horsemen of the proprietary hardware apocalypse: Then, I typically point the person toward the first edition of this book, Asterisk: Integration of voice services into existing Java apps?
A serial entrepreneur, Peter co-founded his first startup while attending Moscow State University where he majored in Computer Science. The authors are noted experts in the field, with years of real-world experience building very large systems. A notable improvement over the second edition is a systematic, logical approach to performance throughout.
The depth and breadth of Asterisk is staggering—installations with hundreds of thousands of users are now commonplace. From the basic beginnings of a PBX that Mark Spencer coded inthe Asterisk project, with the help of thousands of developers, has moved from simply connecting phone calls and has matured into a platform that can handle voice, video, and text across dozens of virtual and physical interface types.
He speaks frequently at conferences. In just a few hours of development or longer, of coursecompanies can change the way they deliver products to customers, nonprofits can overhaul how their users interact with the services they offer, and individuals can learn to build a perfectly customized call-handling system for their mobile and home phones.
The affirmative answers just keep flowing, and at that point, the best thing to do is to sit the person down and start showing him quick demonstrations of how Asterisk can be quickly deployed and developed.
Streaming MP3s into or out of phone calls? The book also includes chapters on benchmarking, profiling, backups, security, and tools and techniques to help you measure, monitor, and manage your MySQL installations.
The Future of Telephonyand set him loose. Emailing recorded conference calls to the participants? My favorite part of any Asterisk project overview or conference talk is answering questions from someone new to Asterisk. He specializes in helping companies fix issues with high-traffic applications dealing with terabytes of data, using hundreds of servers.
Nearly 75 percent raised their hands. There are many new topics and deeper coverage in all areas. I had the fantastic opportunity to work as the community manager for the Asterisk project at Digium for two years, which gave me one of the best vantage points for seeing the scope and imagination of the worldwide development effort pushing Asterisk forward.
I see Asterisk making deep inroads into the financial, military, hospital, Fortune enterprise, service provider, calling card, and mobile environments. Asterisk is a mature, robust software platform that permeates nearly every area of the telecommunications industry and has firmly cemented itself as one of the basic elements in any open source service delivery system.
This chapter includes the table of contents. Yes, yes, yes, yes.

Nearly 3/4 of this 3rd Edition is rewritten and it is expanded to pages. “There’s more than one way to do it.” I’ve been working with Asterisk for nine years, and this motto becomes more true with each release, each added feature, and each clever person who attacks a telecommunications problem with this incredibly flexible toolkit.
As an experienced software engineer but new to the Android system I found this book to be an excellent introduction. I'd attempted to pick up the system organically by installing the dev environment and working through some tutorials.
