Video Layouts in Cascaded Conferences
Without cascading
During cascading
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.
● Identical Conference Parameters defined in the Profile of the conferences participating in the
cascading topology:
Conference line rates
Content rate
Encryption settings
● DTMF codes defined using identical numeric codes in the IVR services assigned to the cascading
conferences
● DTMF forwarding suppressed
● Video layout of the link is set to 1x1 by the appropriate system flag.
Cascaded links in 1x1 video layout use SD resolution.
● When the Mute Participants Except Lecturer option is enabled in the Conference Profile, all
participants (including the link participants) except the lecturer are muted.
● Gathering phase is not supported in Cascading Conferences.
