OpenSER has quickly gained a well-deserved reputation as one of the finest open source VoIP projects. Lightweight yet powerful, OpenSER powers some of the world's largest VoIP implementations.

Up until now, many people have been reluctant to explore the power of OpenSER, due to the steep learning curve, and a sense that it is very difficult to understand.

Finally, a book that lowers the barriers to entry.

Building Telephony Systems with OpenSER is just what the OpenSER community needs in order to grow. This concise yet excellent book takes you step by step through most of the key OpenSER modules, and it does so in a manner that seems to strike the right balance between brevity and depth. I have been reluctant to get into OpenSER, because I remember how painful it was to learn Asterisk without a good book. With this book, I feel that OpenSER just became more friendly and accessible.

It does not matter if you are a entry-level or a professional in the voip field. This book covers the basics and anything else you need to know about how to set up a stable and scalable voice operating platform.

Good book with good explanations and instructions. But a little bit obsolete because there is no more OpenSER. There are Kamailio and OpenSIPS. And they differ from each other and from their "father" - OpenSER.
That is why i'd recommended to buy new OpenSIPS (it exists in Amazon: [...]) and Kamailio (didn't found) editions.

This is a good resource for the non-programmer to get OpenSER v1.2.2 up and running quickly. It was written before the OpenSIPS releases (v1.4 and greater) which subsumed OpenSER. Still this is a great starting point and uses some practical examples to guide the newbie through the world of their first SIP implementation.

The grammar is horrible and the repetition of the text, if eliminated, could probably reduce the book's overall length by a few dozen pages. I understand that the author is not a native English speaker, but where were the editors?
