I tried to find the answer. It seems that nobody knows.

I turned it off and my sound level seems louder via the ear piece.

Actually, voice privacy on CDMA is an added layer of voice encryption. Sprint did some independent research (I've heard quotes as big as a million dollars worth) and determined that CDMA without Voice Privacy is just as secure (unless you've got a million dollars worth of financing to break into an individual phone call)...

In other words, turn the feature off, and don't worry about it.

HowardForums: Your Mobile Phone Community & Resource - what is "Voice Privacy" ?

however...

Quote:

CDMA (Code Division Multiple Access) is the digital telephone standard that was developed by Qualcomm and deployed by Sprint PCS and by Verizon. CDMA used RC4 encryption but the protocol doesn’t keep the keys secret, so in practice CDMA communications can be eavesdropped by a motivated attacker. In practice, though, it’s must easier to wiretap a CDMA telephone on the provider’s network. Today CDMA is used by the Sprint part of Sprint/Nextel and by Verizon.

so maybe there is some use, if you're the paranoid type.
