Product Description
Product Description
SIP is the most important VoIP protocol and OpenSIPS is clearly the open source leader in VoIP platforms based on pure SIP. The whole telecommunication industry is changing to an IP environment, and telephony in the way we know today will disappear in less than ten years. SIP is the protocol leading this disruptive revolution and it is one of the main protocols on next-generation networks. While a VoIP provider is not the only kind of SIP infrastructure created using OpenSIPS, it is certainly one of the most difficult to implement.
This book will give you a competitive edge by helping you to create a SIP infrastructure capable of handling tens of thousands of subscribers. You can extend the examples given in this book easily to other applications such as a SIP router, load balancing, IP PBX, and Hosted PBX as well. This book is an update of the title Building Telephony Systems with OpenSER.
The book starts with the simplest configuration and evolves chapter by chapter teaching you how to add new features and modules. It will first teach you the basic concepts of SIP and SIP routing. Then, you will start applying the theory by installing OpenSIPS and creating the configuration file. You will learn about features such as authentication, PSTN connectivity, user portals, media server integration, billing, NAT traversal, and monitoring. The book uses a fictional VoIP provider to explain OpenSIPS. The idea is to have a simple but complete running VoIP provider by the end of the book.

Format:Paperback
Being the only book on opensips and fairly well written, I had to give this 5 stars. But it does have a couple of flaws. It refers to other sections occasionally which if it included the page or section number, it would help considerably. On one occasion, the section does not exist.
If I remember right (I've had it 10 months) at least one of the code samples was not modified correctly when he converted his openser version of the book, but generally he brings together lots of information available on the internet into one readable book and his code examples are pretty good.
I nearly gave it 4 stars, because I feel he could have so easily added an advanced section. How about developing your own modules, integrating perl, NOTIFY and SUBSCRIBES, load balancing, connecting to other VOIP services etc.
Still, the section on NAT is very good (and essential reading for anybody intending to use Opensips across the Internet). The integration with Asterisk is also pretty good.
I used this book time and time again but only recently have moved onto reading RFCs for the in depth information I need.
If Flavio wrote an advanced opensips (or even a real life SIPS implementation book) I would buy that also.

Great Book on OpenSIPS, But Needs Heavy Editing
30 July 2010
Format:Paperback|Amazon Verified Purchase
I've been working in the telephony industry for several years now, mainly with Asterisk based systems.
My company is currently in need of a SIP proxy to handle load balancing, and least cost routing, so I decided to go with OpenSIPS (which is the most active version of the original OpenSER project today).
This book is the best reference on OpenSIPS available (the official documentation on their website is lacking in many regards), and is worth purchasing if you need to learn how to setup and configure OpenSIPS.
I'll try to give an honest breakdown of my thoughts on the book.
PROS
- Contains extremely detailed configuration file directives. This is probably the bulk of the book (snippets of code from the configuration files). This makes the book worth its purchase price.
- A great introduction to SIP, which discusses the protocol in an unusually simple manner.
- Contains a section on managing OpenSIPS through two different web panels, which is nice for IT people who may need to handle configuration changes from time to time.
- Contains a section on LCR, which is obviously extremely important for modern SIP proxies.
- Contains a section on billing, which is equally important. Most people setting up SIP proxies are VoIP providers, and need to charge for access.
CONS
- Lots of typos and grammatical errors. It is obvious that the author is not a native English speaker. While the text was well written, it should have been heavily edited. A lot of the sentences / paragraphs don't make sense, aren't clear, and are confusing.
- There is not a good explanation of why configuration directives work the way they do. The author presents valid configuration examples, then just reads off short 1 sentence descriptions of each field. I thought that this could have been written much better, as this is the primary reason most people will purchase the book.
Overall, this is a necessary reference for anyone who is using OpenSIPS. It is definitely worth the money, if only for the rather complex configuration samples inside.
I hope that the next version of the book has a much more strict review and editing process.

Awesome book. Worth the money.
28 Nov 2011
Format:Kindle Edition|Amazon Verified Purchase
Easy to read. The author begins by explaining in detail the SIP protocol, abstracting the reader of the always painful RFCs. Then he takes us into the world of OpenSIPS together with a number of practical examples.
The book also covers some aspects of the integration of OpenSIPS with Asterisk, which was precisely what I was looking for.
I highly recommend this book. Worth the money.
