In order to avoid cluttering in the cascaded window, it is advised to select appropriate video
layouts in each conference before cascading them.
Figure 5-11Video Layouts in Cascaded Conferences
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.
Flags controlling Cascade Layouts
Setting the FORCE_1X1_LAYOUT_ON_CASCADED_LINK
_CONNECTION System Flag to YES (default) automatically forces the cascading link to
Full Screen (1x1) in CP conferences, hence displaying the speaker of one conference to a
full window in the video layout of the other conference.
Set this flag to NO when cascading between an RMX and an MGC that is functioning as
a Gateway, if the participant layouts on the MGC are not to be forced to 1X1.
