Practical Asterisk 1.4 and 1.6 (ePub)

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.
