Just looking thru my phone settings and ran across it. I hesitate to turn on anymore notifications. Pretty soon the phone will be telling me to blow my nose!

lol, I couldn't stop laughing after reading your post.

That's a good question. It's not posted anywhere. I've found others that have asked the question, but it wasn't answered.

I've turned mine on temporarily to see what it does.

this is kind of a network specific feature (such as caller id and 3 way calling).

if the network you are using supports voice privacy encryption, you will be notified by a tone once you connect.

this was on my old nokias back when i was on bellsouth mobility. they (bell mobility) didnt offfer vocie privacy but the nokias had the notification so even though they didnt have it i would stil get a tone which meant that is was not supported. (one tone meant it was supported, while another tone meant it was not).

i dont think sprint supports it.

ah ok, thanks Marc. I've been wondering what that unlocked icon was when you turn the option on.

Voice privacy is a second level encryption for your voice call on a CDMA based network. The base CDMA standard is allready encrypted and the only time you might want "voice privacy" is if you were roaming. CDMA breakes up your call into tiny segments and transmits it on whatever frequency is availible at that time so in order for someone to listen to you not only do they have to be able to jump frequencies instantly, and recieve the person on the other line on a compleatly diffrent frequency, they also have to seperate your call from another call that is on the same frequency happening at the same time, and then they have to crack the unique code given to every call. To Sprints knowledge this has only been done 1 time, it was done by Sprint to find out if it could be done, and it cost over $1,000,000 to do it (yes that is the correct amount of 0's). Of course if your a three letter government organization, i would imagin they could do it fairly easily.

Falconier, would that be Langley, Fort Meade or DC?

A brilliant blogger named Den Beste runs a site called USS Clueless. Apparently he made a killing in cellphone engineering and retired young. He has a good and challenging cell phone FAQ at

http://denbeste.nu/cdmafaq/index.shtml

By digging through there and related essays, you can learn a LOT about cellphones, and the difficulties of tapping them. If I read this material correctly, data is conveyed BELOW bit level (!).

You've noticed how people don't even tell old wives's tales about having their cell phones tapped. You hear about governmental authorities tracing people's locations through cellphones (i.e. OJ's run for the border in '95), or court-ordered wiretaps through switching stations.

But in terms of creepy neighbors listening in to find out what kind of sex you like or where you get your Chinese carryout, it just doesn't happen. And apparently the technology of cell phones is going to KEEP your calls private for a very long time. It will be many years before the teenager next door has the technology to listen in.

But who knows whether the government is using voice-recognition technology to search for terrorists. If they are, I hope it works better than Fonix!

I read the article that that blog person made, its pretty interesting. I knew that the data was encrypted but acording to him its encrypted 3X. I guess if Voice Privacy was enabled that would be 4X and compleatly redundant (unless your compleatly paranoid).
