Check this post for a recap of the FreePBX configuration modes and my first thoughts.Last time I looked at this I thought … Continue reading Revisiting device-and-user mode in FreePBX

I thought it was something specific to (K)Ubuntu, but when I had the exact problem on my NSLU2 running Debian I figured the problem … Continue reading Trouble with apt-get and Squid
We watched WALL-E the other day. A bit of trivia for Apple Mac fans (if you didn't already know) is that WALL-E's startup sound — heard when he's finished his solar recharge — is that of a post-1997 Mac computer (with Steve Jobs on the board of Pixar and Disney, WALL-E was never going to … Continue reading Classic Mac sounds on my mobile phone
