According to:

All the GSM vocoders listed support a mode for data and facsimile
distinction versus voice.  So it appears as if the modes exist to get
a decent data channel over the encoded voice.

This yields the question: can you actually get the encoded digital
stream of voice out of the prefabbed devices to do the required
processing?  You lose the ability to automatically decode the voice on
the module, but if encrypted voice is what you want it would seem this
to be a viable option.
