Biography

Leif Madsen first took an interest in Asterisk while attempting to find a voice conferencing solution for him and his friends. After someone suggested trying Asterisk, the obsession began. Wanting to contribute and be involved with the community, and noticing the lack of Asterisk documentation, he co-founded the Asterisk Documentation Project. Leif is currently working as a consultant, specializing in Asterisk clustering and call-centre integration. You can get more information at http://www.leifmadsen.com

June 30 2009

So last night I did a system update between 11:30pm and 5:00am. One of the things I forgot to do when I was moving to the new system was to install sox so that MixMonitor() could mix the -in and -out files automatically for me. I still had the recordings,… read more

June 29 2009

So I finally got around to converting my very old, very outdated, and very difficult to update website to Drupal from standard HTML.

The end of the beginning?

May 22 2009

This is probably my fourth or fifth time attempting to setup a blog. Everytime I finally get something going, then either a server crashes, or some other catatrophic event that causes me to start all over again happens. So this time I’m going to use the wordpress.com site to keep… read more
