asterisk users - Jan 2005 - Streaming Audio - Music On Hold Feature

I was wondering, does anyone know if it is possible to have a stream of 
audio coming from a Microsoft compressed audio stream fed to the caller if 
they are placed on hold and if so how might this be done?

I have not used any M$ products, but it works with shoutcast like this:

default => quietmp3:/var/lib/asterisk/mohmp3-empty,http://host.com:8000/

basically, create an empty directory to point it to first, then the
url to the stream.

If the microsoft stream can be played via url in winamp in MP3 format,
then it should work about the same.

Write a shell script called mpg123, located in /usr/bin or 
/usr/local/bin that spits audio out on it's STDOUT in the correct 
format.  I think the format is 8khz, mono, 16-bit.  You can set up music 
on hold with mpg123 the just do a px -axwww to see what parameters 
Asterisk uses to start mog123, read the mpg123 man page and then make 
your script output the audio in the same format.  Or you can just look 
at the Asterisk source code for the options.

It's not hard to write the script.  It's hard to make the script do the 
right thing when you have network problems and get disconnected from 
your streaming source.
