Yes, but you'll have to build the hardware yourself.

The commercial products took a dumb hardware smart software approach and
did the DSP in software using the zaptel API. There's over 10 years of
history and the driver is in the mainline kernel.



I can imagine an ATA that is smart enough to speak ZRTP and do key
verification with a recorded voice or print out the SAS on an LCD/LED
screen.
