About Leif Madsen

I currently work at Red Hat on the NFV (Network Functions Virtualization) partner engineering team as the DevOps lead. In this role I work with telecommunication partners to automate and test their NFV platforms.

In a previous life, I was an Asterisk consultant, starting professionally in 2004 (learning Asterisk in September 2002). I’m co-author of the O’Reilly Media published books, Asterisk: The Future of Telephony 1st and 2nd editions (along with Jared Smith and Jim van Meggelen), Asterisk: The Definitive Guide (3rd and 4th editions) with Jim van Meggelen and Russell Bryant, and the Asterisk Cookbook with Russell Bryant.

As a former active member of the Asterisk community, I was the primary issue marshal on the Asterisk issue tracker, in addition to the Asterisk release manager. Some of the notable projects I built or implemented include:

I’ve also spoken at many Asterisk conferences, helped write the first Asterisk training classes and dCAP (Digium Certified Asterisk Professional) training and certification, helped to steer the implementation of several features in Asterisk, and performed consulting for dozens of clients over the years.

Leif resides in Alliston, Ontario, Canada but has worked remotely for customers all over the world.
