    what is "Voice Privacy" ?

    on the PPC-6601, I've got something called "Voice Privacy", under the phone options, i also have a checkbox for "notify me when voice privacy is unavailable".

    what is this voice privacy thing?

    it's a holdover from the days of tdma and analog. it is just voice encryption. which is mandatory in cdma. don't worry about it.
    My awareness flows through the rivers of existence which pulse with the vibrance of my thoughts.

    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.

    Yeah, but on Windows Mobile, the voice privacy option will leave your Phone app marred with a worthless padlock icon that will always sit there unlocked.

    I have noticed that on My G1000 too. Is the performance and call quality the same with it on as with it off?

    Calling CDMA "encryption" is merely security through obscurity. OpenSource SDR on commodity PC hardware makes receiving a CDMA carrier very affordable.

    Employing encryption, or "Voice Privacy" probably meets some sort of specification for federal agency usage.

    moral of the story: it doesn't matter to any standard consumer.

    One can receive anything, fairly affordably,
    CDMA carrier, included.

    That CDMA carrier, however, is a very
    complex "beast". As someone else
    already posted, it's quite expensive
    to "pull that carrier apart" into its components.

    If you want a more detailed elaboration
    as to why it's still (even with a carrier
    "deconstruction") difficult to tease
    out a particular phone call over the air,
    search back with alt.cellular.sprintpcs
    for both postings from paul@wren.cc.kux.edu and cinema@ku.edu
