Enabling Encryption in the Profile
Encryption for the conference is in the Profile and cannot be changed once the conference is running.

To enable encryption at the conference level:

»In the Conference Profile Properties – Advanced dialog box, select one of the following Encryption
options:
Encrypt All - Encryption is enabled for the conference and all conference participants must be
encrypted.
No Encryption - Encryption is disabled for the conference.
Encrypt when possible - enables the negotiation between the MCU and the endpoints and let
the MCU connect the participants according to their capabilities, where encryption is the preferred
setting. For connection guidelines see Mixing Encrypted and Non-encrypted Endpoints in one
Conference.
For more information about recording encrypted conferences, see Recording Link Encryption.
Enabling Encryption at the Participant Level
You can select the encryption mode for each of the defined participants. Encryption options are affected by
the settings of the flag in the system configuration. Undefined participants are connected with the Participant
Encryption option set to Auto, inheriting the conference/Entry Queue encryption setting.
