Asterisk Music on Hold improvement

March 30, 2006 2 comments

live mp3 decoding is CPU intensive, and can be a major factor in asterisk server performance when there is a music on hold component to the scripting. I came across a great solution to the problem: change the music to the native sound format. The transcoding is done one time rather than every time. (Link). It totally solved a music quality issue we were having at SSG. I used the batch script to convert all their music files (which were royalty free mp3 files from signate) at once.

I’ve had to install Citrix on Linux several times, and there were too many things to remember. Here’s a concise list for Ubuntu:

sudo apt-get install libxaw6 libmotif3

sudo ln -s /usr/X11R6/lib/libXm.so.3 /usr/lib/libXm.so.3

Advanced QOS for IPCop

March 10, 2006 Leave a comment

I have replaced my Sonicwall firewall with IPCop on a recycled Dell Optiplex GX1 with an extra NIC. It works better for VOIP, but VOIP would still get choppy if I abused my connection too much (3.0 down/624 up dsl)

I downloaded QOS v.2.5.9 addon from mhaddons from sourceforge

The only tricky part was using port 222 instead of 22 for ssh/scp. I used Fugu on my Mac to get the software over to the box. Otherwise I followed the instructions here, and it was pretty straightforward.

MythTV & Ubuntu Breezy

March 9, 2006 Leave a comment

I recently got MythTV working on my Ubuntu Breezy box. Installing MythTV was a bit of a battle, but it is really cool. I've been spending more and more time on that Ubuntu machine. more and more it is getting to be as useful as my Mac is, though there are still a few missing critical pieces for me. My main XP machine hosed up, and I decided to turn it into a firewall instead and put a second head on my Mac. My other XP machine is now used almost exclusively for the kids to play games on, and to extract recordings from my Dish Network DVR. I do spend a lot of time on my 2003 terminal server, but I can do that from any of my other machines.
