Conference Encryption Mode
You must have a security key for your Cisco Telepresence system to utilize encryption.
Define the conference encryption mode. A padlock with the text "Encryption On" or
"Encryption Off" displays on screen for a few seconds when the conference starts.
NOTE: If the CE-NC software (no crypto) is installed on the video system, the encryption
mode is always Off.
Requires user role: ADMIN
Default value: BestEffort
Value space: Off/On/BestEffort
Off: The system will not use encryption.
On: The system will only allow calls that are encrypted.
BestEffort: The system will use encryption whenever possible.
> In Point to point calls: If the far end system supports encryption (AES-128), the call will
be encrypted. If not, the call will proceed without encryption.

support encryption. If not, the conference will be unencrypted.
