This bestselling book is now the standard guide to building phone systems with Asterisk, the open source IP PBX that has traditional telephony providers running scared! Revised for the 1.4 release of the software, the new edition of The Future of Telephony reveals how you can save money on equipment and support, and finally be in control of your telephone system.
If you've worked with telephony in the past, you're familiar with the expensive and inflexible systems that are tuned to the vendor's needs, not yours. Asterisk isn't just a candle in the darkness, it's a whole fireworks show. Because Asterisk is so powerful, configuring it can seem tricky and difficult. This book steps you through the process of installing, configuring, and integrating Asterisk with your existing phone system.
You'll learn how to write dialplans, set up applications including speech synthesis and voice recognition, how to script Asterisk, and much more -- everything you need to design a simple but complete system with little or no Asterisk experience, and no more than rudimentary telecommunications knowledge. The book Asterisk is revolutionizing the telecom industry, due in large part to the way it gets along with other network applications. While other PBXs are fighting their inevitable absorption into the network, Asterisk embraces it. If you need to take control of your telephony systems, move to Asterisk and see what the future of telecommunications looks like.
El libro que marcó mi carrera, lo leí en 2010 y me enseñó las posibilidades del mundo VoIP. Ahora, a 17 años vista de la publicación de su segunda edición el mundo es completamente diferente. En su contexto una muy buena guía y manual de referencia sobre el proyecto VoIP que para mí, lo cambió todo.
An excellent reference into establishing your own PBX system. It accurately and comprehensively explains the options and tradeoffs for internal and external communications.
As a side note, the extreme effort required to offer phone termination (bridge between voip and PSTN) as well as SMS means that for most non-PBX purposes, one would be better served by telecom as a service (e.g. Voxeo or Twilio).
helped me learn quite a bit about asterisk, and was the only book i really was able to find to learn asterisk. Good read if your looking to learn about asterisk.
