In order to avoid cluttering in the cascaded window, it is advised to select appropriate video
layouts in each conference before cascading them.

Guidelines
To ensure that conferences can be cascaded and video can be viewed in all conferences the
following guidelines are recommended:
•
The same version installed on all MCUs participating the cascading topology
• The same license installed on all MCUs participating the cascading topology
• Same Conference Parameters are defined in the Profile of the conferences participating
in the cascading topology
— Conference line rates should be identical
— Content rate should be identical
—
Same encryption settings
• DTMF codes should be defined with the same numeric codes in the IVR services
assigned to the cascading conferences
• DTMF forwarding is suppressed
• The video layout of the link is set to 1x1 by the appropriate system flag.
• When the Mute Participants Except Lecturer option is enabled in the Conference
Profile, all participants (including the link participants) except the lecturer are muted.
Only the lecturer is not muted.
