Recording Link Encryption

Recording Links are treated as regular participants, however the
ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF system flag 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.
Enabling Media Encryption for a Conference
Media encryption is enabled at three levels:
●MCU level - Setting the Encryption Flags
●Conference level - Enabling Encryption in the Profile
●Participant level - Enabling Encryption at the Participant Level
You must first set the system flags for the MCU before media encryption can be enabled for the conference
and participants.

Setting the Encryption Flags

Enabling the media encryption for the MCU is usually performed once an it is applicable to all conferences
running on the MCU.

To modify the Encryption flags:

1Click Setup>System Configuration.
The System Flags dialog box opens.
2Set the
FORCE_ENCRYPTION_FOR_UNDEFINED_PARTICIPANT_IN_WHEN_AVAILABLE_MODE flag
to YES or NO.
3If recording will be used in encrypted conferences, set the
ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF flag to YES or NO.
4Click OK.
For more information, see Modifying System Flags.
