SIP Trunking – book review

This book is waiting on my desk for a while now. I’ve been busy with BSCI and only now found the time to open it, while working on my ONT exam.

I do some maintenance and configurations on my partial IP phone system (Avaya PBX) but it is definitely not the core of my work, not to a level that can be considered as good experience. So I’m new to the VoIP and QoS world and reviewing this book while watching the ONT videos and reading the books is very interesting.

SIP Trunking by CiscoPress is a high level resource that cover a relatively new trend in the IP telephony world.
ISPs and LAN environment converted to VoIP and IP telephony but they still use TDM trunks, the old method or in its other name – the bottleneck.

With SIP (Session Initiation Protocol) you can gain
Point-to-Point VoIP and get better service, QoS and flexibility.

The Book has a clear and very interesting introduction part. As I said, I’m not a big voice expert but I had no problem understanding the concepts, the benefits and the problems.

The second part focus on the design, planning the network for SIP trunking. It covers the component, the trunking models and design considerations. I was able to find many familiar scenarios of different types of offices and get the idea of the added value of SIP trunking.

The third and last part is the deployment of SIP trunks, this was just over my head with commands and case studies that go beyond my understanding (at least at this point of my VoIP life).

Overall I enjoyed reading this book and learned many concepts and models beyond SIP trunking. If I had to work on a SIP project this book would be a good resource and is very recommended. It is also a great book for anyone who work with telephony (IP or not) – this is where the world is moving to and even if you do not see the immediate value, it will prove beneficial on the long run.

Since I’m running a small shop I do everything and this is the type of book that allow me to better understand the big picture. I will definitely read it again after my ONT exam and I assume that with my additional knowledge and some (very basic) lab experience I will be able to get more out of it.
