Guidelines to Related Issues
● Recording link layout is not altered, as well as the layout sent to the recording link. The recording link
layout displays as many participants as possible, with the recording link cell the first to be discarded.
● Discussion Mode is inactive when in Legacy content mode (i.e. content sent via people video layout).
● In cascading conferences, depending on the value of the system flag
FORCE_1X1_LAYOUT_ON_CASCADED_LINK_CONNECTION:
 When value is YES - Only the active speaker is sent over the cascading link, where that link is one
of the participants in the Discussion Mode layout.
 When value is NO - The Discussion Mode layout is sent over the cascading link, and is displayed
in the cascading link participant cell.
Interaction with Other Features
● Participants may be assigned a Personal Layout.
● A participant may set its own layout via Click & View.
● Participants layout may be modified via PCM.
● Discussion Mode is applicable in Same Layout scenarios.
● Discussion Mode is inactive in Presentation Mode, Lecturer Mode, and Telepresence Mode.
● When Exclude Static Room from Layout is on:
 Static rooms video is the last to be displayed in Discussion Mode layout cells, unless it belongs to
either the current or last active speaker.
 The DISCUSSION_DISPLAYED_PARTICIPNATS_TO_START system flag counting may take up
to two static rooms into account.

affects new conferences (i.e. not reset required).
Default value: 8

with the speaker cell included.
The time interval, in seconds, after which a participant becomes an active
