Implementing Media Encryption for Secured Conferencing

Recording Links are treated as regular participants, however the system flag 
ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF must be set to YES if a 
non-encrypted Recording Link is to be allowed to connect to an encrypted conference.

The following table summarizes the connection possibilities for a Recording Link that is to be connected to 
a conference for each of the conference profile and Entry Queue encryption options.

Media encryption is enabled at three levels: 

● MCU level - 

● Conference level - 

● Participant level - 

You must first set the system flags for the MCU before media encryption can be enabled for the conference 
and participants.
