Sebastopol, CA--The telephony revolution is underway--a transformation fueled by an open source PBX called Asterisk.
"Asterisk lovingly embraces the concept of standards compliance, while also enjoying the freedom to develop its own innovation. What you choose to implement is up to you--Asterisk imposes no limitations," explain the expert authors of the new edition of Asterisk: The Future of Telephony (Jim Van Meggelen, Leif Madsen, and Jared Smith, O'Reilly, $44.99).
Updated and expanded for the 1.4 release of the software, this major revision shows readers how they can save money and stay in control of their telephone systems. The new edition also includes greatly expanded coverage of SIP, databases, and up-to-the-minute information on management and administration.
Indeed, using Asterisk, developers can tinker with their phone calls just like mechanics tinker with their cars. They can add features, increase performance, add redundancy, and increase collaboration. With Asterisk, users are no longer dependent on expensive and inflexible systems that are tuned to the vendor's needs, rather than the end user's.
Yet Asterisk's flexibility comes at a price, however: it's not a simple system to learn and configuring can seem tricky. Fortunately, this new book offers a detailed roadmap--guiding every user through the process of writing a dialplan, integrating phone systems with a relational database, scripting Asterisk with the manager interface and AGI, using Ruby on Rails with Adhearsion, and much more.
Indeed, this timely new book covers everything users need to design a simple but complete system with little or no Asterisk experience, and no more than rudimentary telecommunications knowledge.
The new edition includes:
The future of telephony is here--and with Asterisk: The Future of Telephony, readers can embrace it, too.
