In the time that’s lapsed since VoIP Hacks was published, many of the contributors have done pretty amazing things. Top of mind is Brian Degenhardt, who now works for Digium, vis a vis his role at Switchvox, one of the top Asterisk PBX makers anywhere.

Anyway, here’s a snippet from the review:

Before reading this book I would not have considered putting an IP-PBX on an ADSL link. The author’s idea of putting a Sangoma ADLS modem in the Linux box with PPPoE client software and controlling the modem queue is nothing short of genius. Then to top it off with the AstShape QoS scripts and the QoS monitoring tools, this book is an absolute bargain. With these tools I’ll not only know if the ADSL connection is capable of supporting VoIP service, but I’ll know exactly why. Much better than cutting over to the VoIP system and later discovering the problems. The whole book is just full of great ideas.
