Guidelines for Setting the Video Layout in Cascading Conferences

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.
● Cascaded links in 1x1 video layout are in 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. Only the lecturer is not
muted.
● Gathering is not supported in Cascading Conferences.
