In this chapter, I tried to present some of the things that I think will help you. I would like to write a lot more, but one day the book has to finish. OpenSER versions change very often and most of times the scripts are not totally compatible with the previous version. This is a nightmare for anyone trying to write about a topic. I spent a lot of time changing this material from 1.0 to 1.1 and to 1.2 and by the time I wrote this, 1.3.1 is available. I decided to stop running like a "dog chasing its tail" and publish the material with version 1.2.x. I'm making available the script adapted to 1.3.1 in the packtpub support website. Please check this area for newer scripts when new releases are made available. I hope this book helps you. Countless hours were spent testing the labs and migrating from one version to another. I hope all this effort benefits you and enables you to avoid all the time I have spent debugging.
