In order to avoid cluttering in the cascaded window, it is advised to select appropriate video
layouts in each conference before cascading them.
Figure 5-11
Video 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.
