first thanks for all answers, my head is spinning around. :)
i see, there are many ideas. I begin first with "Hardware-hacking", and 
  i think i beginn with chris idea. Or is it possible to read the 
modem-device directly? (how the modem-device calls in /dev/..? or 
somewhere)
I have a lot of telephons, and i want these as a 
sequenzer/synthesizer-interface without to loose the "soul" of the 
telephons. They should ring, answering/calling, controll in a rhytmic 
context.
Then expand the project to controlling/answering with a pd-callcenter 
over the (telephon?-)network would be the next step..

i will keep you posted with my work
