Can you explain a bit more about that hardware IP phone. Maybe a link ? Could 
i just connect that to the network ? 
USB support is working already, the sound-chip, i must check on that. I think 
the newer LTSP-4 would be ideally for that, because you can configure some 
stuff to run locally. Should try that some day.

I was thinkingh the use max 1 phone /thinclient, so for the moment beingh, 
max 5 phones / LTSP server. But yes, maybe it is too much for that one 
server, but i could easily put another one nearby it.

Never thought about that, but i think on every location, there will still be 
one classical phone .
