Using the open source Asterisk platform, you can deploy a state-of-the-art VoIP PBX on a low-cost PC or server for a fraction of the cost of conventional PBX systems. The only drawback to Asterisk is its notoriously poor documentation. Practical Asterisk 1.4 and 1.6 is the solution to that problem. This book provides all the detailed, real-world, ground-level information you need to plan, install, configure, and reliably operate Asterisk in any environment.Other products from Pearson Education (InformIT)
