well the use case I gave is about as good as I can come up with. Radio
would apply to the same use case, as radio has the same bandwidth and
frequency range as a POTS line.

internet is sort of vague but yes ability to record to a WAV file or
the likes, PGPfone appears to handle that in the use of something like
skype but that might be a little out of scope as I am looking for that
analog conversion which typically wouldn't take place on the internet.

and cisco phone is not really in scope as its proprietary and it has
that functionality with certificate biased encryption already, however
it wont traverse to the POTS phone so it wont fit the use case.

Is there any software that will encrypt voice on the fly? I know there
is PGPfone but that's for use with a existing VoIP Phone product.

My use case is.. if I want software to encode my voice in software on
a laptop over a POTS or Cellular phone do decrypt via far end software
and phone. I understand the limitations to some of this due to the
audio spectrum available on the equipment but not asking if its
possible more, is there software that (ideally opensource) that will
do this?
