[PD] Pd + asterisk?

[Hans-Christoph Steiner]

I am also quite excited about this, I think it can provide some  
really interesting new ways of interacting with phones, possibilities  
for composition, or whatever else we can dream up.  I am really into  
the idea of live audio processing of phone calls then feeding back  
synthesized audio into the phone call.

I just had a thought about this, perhaps it would make more sense to  
make Asterisk use Jack (http://jackaudio.org/) as the interface for  
transferring audio to Pd.  It's a common standard, it runs on GNU/ 
Linux, Mac OS X, is alpha on Windows.  It would allow Asterisk to  
interface with a wide range of audio apps that support Jack.  AFAIK,  
you can dynamically allocate and deallocate jack "channels".  There  
is already some support for managing the jack channels in Pd, and I  
don't think it would be too hard to support.

So the idea would be that for each call that is sent to Pd, it would  
open up a jack channel and notify Pd about it.  The question there is  
whether Jack can support hundreds or thousands of channels.
