Recording Link Encryption
The Recording Link can be encrypted when recording an encrypted conference. The
encryption of the Recording Link is enabled when Encryption is selected in the Conference
Profile on the Collaboration Server and on the RSS, and the system flag
ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF is set to NO.
Recording Link Encryption Guidelines:
•The Recording Link connection type must be H.323.
•The Recording Link uses the AES encryption format.
•The RSS 4000 recorder must be set to support encryption. For more information see the
RSS 4000 User Manual.
• Encryption must be selected in the Conference Profile.

Recording Link Encryption Flag Setting

Recording Links are treated as regular participants, however if the
ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF System Flag is set to
YES a non-encrypted Recording Link is to be allowed to connect to an encrypted conference.
Table13-4 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.
