This sounds almost impossible. In standard carrier grade voice transmission
you can pass 31 calls with 2 Megs (64 kbit/s per call). In your case you
have 21kbit/s per call. Plus you want this encrypted, which means you will
have even less quality. You can do it, but you will loose a lot of
frequency. 
Loosing frequencys means one can not hear the  temper of the caller. 

What is your concentration factor?
