music on hold without mpg123

[Lenz <lenz-ml (at) loway.it>]

Hello list,
after the last time that mpg123 wen ballistic on our production system, we  
decided to skip mp3 playback altogether and to go for raw files. After  
half an hour playing with mpg123 and sox parameters in order to translate  
a mp3 file to a wav file that can be streamed back through * with no need  
for an mp3 decoder, I thought I'd post the result to the list to avoid  
wasting time in the future:

The correct paramater set seems to be:

mpg123 -s --rate 44100 --mono /src/mp3/fpm-sunshine.mp3 > fpm-sunshine.raw
sox -r 44100 -w -s -c 1 fpm-sunshine.raw -r 8000 -c 1 fpm-sunshine.wav

I have also prepared a small tutorial explaining how to setup the whole  
thing (you can find it at http://www.oinko.net/astrecipes/index.php?n=152  
- feel free to add or modify it if you think it's necessary).

Thanks
l.
