Note: this article was written by Daniel-Constantin Mierla alone, being a personal selection of who or what was considered to have impacted the evolution of Kamailio project to become what it is nowadays.

This is part of a series of articles dedicated to celebrating 20 years of development for Kamailio project.

Next group of 20 people combines developers and persons that had key roles in sustaining or promoting the project.
