Support -> Devel Course

The OpenSIPS development Course was addressed to people who want to develop (C development) new modules or functionalities for OpenSIPS 1.x.

The course aimed to present and familiarize developers with the internals of OpenSIPS both core and modules. During the course you got a real example of how to build a new module (with DB, MI, variables, events, etc) from A to Z.

This is an hands-on training, so the only materials presented in this course were the schematics (whiteboard drawings) and the C code of OpenSIPS - there is a highly technical course, so no slideshows ;) .

The entire course was recorded and the resulted materials were compiled and used as a "Development Documentation" for OpenSIPS.

This course is free and sponsored by OpenSIPS Solutions .
