Encrypted GSM calls are basically not feasible
to transfer encrypted voice you need a data link between the both ME, GSM 
creates GSM-codec voice path, not a data path. Means your data gets mangled by 
carrier's audio processing. You *can* *not* send data at a reasonable speed 
over a GSM voice call link.
