Voice encryption

Your OpenStage 40/40 G, software release 2 (V1 R2.xxxx) and later, sup-
ports voice encryption on HiPath 4000 V4 R1. This allows you to use your
OpenStage to perform tap-proof calls. Voice transmission is encrypted and
data is decrypted at the other call party's phone and vice versa.
There is a difference between secure modes "Cipher Mode" and "Secure
Mode".
In idle mode, you can see which secure mode is activated on your Open-
Stage display
Cipher Mode
To guarantee that your calls are always secure, your service personnel can
activate "Cipher Mode". In this mode, voice transmission is always encrypt-
ed, even when it is to a phone that does not support voice encryption.
However, this may cause a loss in call quality.
If your phone is in "Cipher Mode", you receive the message "always en-
abled" when you query status
Secure Mode
If "Secure Mode" is enabled on your phone, and a connection is established
to a phone that does not support voice encryption, the call is not encrypted
and thus unsecured.
Your service personnel can define at the communication system whether
you are notified of unencrypted calls and how
If your phone is in "Secure Mode", you receive the message "enabled"
when you query status
