Welcome to LeifMadsen Enterprises, Inc!


LeifMadsen Enterprises, Inc. is no longer taking on consulting clients. Leif has moved to full time employment at Thinking Phone Networks. If you're in need of a high quality, large scale unified communications platform (500+ seats), please head over there.

Alternatively, find my recommendations for consultants below:

  • Russell Bryant (Russell Bryant Enterprises, LLC): Russell Bryant is an expert Asterisk developer. He has the second most commits to the Asterisk source code (1st being the Asterisk creator, Mark Spencer). He takes on projects that require modifying the Asterisk source code. This could include bug fixes, new features, or porting of existing changes. Contact Russell.
  • Paul Belanger (Polybeacon): Paul Belanger is a DevOps master, deploying and maintaining systems with the Kickstand Project. He takes on projects that require deployment and maintenance of Asterisk systems with a sane methodology and focus on being reproducible in both production and development. Contact Paul.


You can find the blog for Leif Madsen by clicking on the Blog link in the top menu bar. This blog delves into more advanced topics of Asterisk, and is certainly something you should stick into your RSS feed.

This is where you'll find out about the most recent goings-on of Leif Madsen. A definite must-follow!
