in a nutshell, is there any available (preferably Java based, since
most cellulars nowadays support Java) application that allows client

The solution you are looking for pretty well has to be VOIP with
encryption, as mobile operators don't pass voice bits in the right way -
and they only encrypt the link between user and mast, whereas you are
looking for end-to-end encryption.

I was going to ask essentially the same question:
Are there any [iPhone] apps for encrypted digital voice
conversations end-to-end (i.e., both the caller and the
callee would need to run the same app on their ends)?

Obviously, this would have to involve some kind of PKI
library and a way to exchange public keys at the start
of a call connection.

I don't know the details of the iPhone architecture, so I'm not
sure if user apps have full access the the voice data stream,
allowing them to insert themselves between the receiver/transmitter
codec streams.
