There is no known mechanism in the software realm that will
encrypt or decrypt on the fly if your intentions are to say
have every call you make "encrypted". Supposing you had uber
product A installed and configured to properly encrypt your
sessions. You'd need that same software or hardware on the
other end to perform the functions as well. Period.

You're comparing apples and oranges when it comes to VoIP
and POTS. You need some software mechanisms to encrypt on
both ends. How do you propose the phone on the other end
of a POTS line decrypt. They'd need some hardware to do
the conversion after the VoIP trunk to PSTN termination.
It would have to be some form of IP in some form of telco
equipment to do such a thing.

Anyhow, enjoy the reading:
