thx a lot russel...your hack actually works!! 
Meanwhile I've found something about the musiconhold-conf-option
"cachertclasses", which might help in starting a separate instance for every
caller. however, that didn't really work for me... probably this option only
works for mode=files?!

anyway, thx a lot for your suggestions
regards,
michael

Most players don't work quite correctly with Asterisk MOH. For it to work
the
way you expect, the player you are using must throw away the audio when
Asterisk
isn't currently reading from the stream. There was a magic version of
mpg123
(0.59r IIRC) that did that, and that is why it was the recommended
version.
If you're reading from a raw TCP stream, then you can use the small
streamplayer
utility included with Asterisk. Otherwise, I don't really have a good
suggestion for you right now. I suppose that you could use some sort of
hack to
ensure that music on hold is always playing so that the stream is being
serviced.
