After almost one year, the new book about OpenSIPS is going to be published on the next week by Packt Publishing UK. This revision was really tough, it started with OpenSIPS 1.5,then in the middle of the book we decided to change to 1.6 using the beta version then, finally when the 1.6 was released, we discovered that many things had changed and a new rewrite was required to finally release the book on the latest version of the software. I hope you enjoy the new book, it will contain a code pack with all the code shown. The book will be available from Packt www.paktpub.com and in the main bookstores.  OpenSIPS (former OpenSER) is one of the most advanced platforms for IP telephony using SIP. It is widely used by VoIP providers and large enterprises.  I would like to thank the reviewers Bogdan andrei Iancu and Justin Zimmermann and to Packt Publishing staff that help me to make the book a reality. .

Tutorial: Installing OpenSIPS 1.6.4 on CentOS 5.5 with mi-xmlrpc

Recently, I heard from some people that is difficult to install OpenSIPS, mainly the mi_xmlrpc module on CentOS. Some servers do not support Debian or Ubuntu,where the compilation process is quite simple, but in most cases they support RedHat and CentOS. The instructions below are valid for both. Using the preinstalled operating system is sometimes valuable because of the tech support and improved drivers. The objective of this tutorial is to show how to compile successfully OpenSIPS on CentOS. This configuration was tested with CentOS 5.5.

This assessment test is a bit old, but still valid. I have created it a few years ago, but I don't know why it got removed from the website. I hope you enjoy.

Hi, 

Today is January, 1st, I hope you have had a wonderful new year's party. As most of people I had created a list of things to do for the year to come and yes, dieting is again on the list. Well, related to Asterisk, I have decided to update the eBook to "Asterisk 10" this year and give away the PDF for free. The last time I've been in Argentina for 4Kconference I was so well treated, that I could have a dimension of what means to write a book. Several people came to me to say thank you for the book and talk about how they have learned to install and use Asterisk using the book. I received several email from people around the world giving me a nice feedback. Life is made of good moments, and the Asterisk Guide has brought me many of these moments, that no money could buy. So I decided to give the Asterisk 1.6 PDF english edition for free, Asterisk 10 should be ready in 6 months. I hope you enjoy. Asterisk is a revolution, it has touched so many people in so many countries, I'm proud to contribute, even being so little.
