Explanation
Switching policy: Two types of switching policy are available:
◦ Room switching: Room switching switches the video from all table segments of a room to all other
rooms in a meeting. If the active speaker (loudest speaker for approximately 2 seconds) changes, all table
segments in the new active speaker's room will be displayed in all other rooms at the same time, replacing
the previously active room.
◦ Speaker switching: Speaker switching allows each segment to be switched independently, so that at
any given time the three active segments, in one or multiple rooms, are displayed in all Cisco
TelePresence rooms. If the active speaker changes, the speaker's table segment will be displayed in all
other rooms on the corresponding screen, as shown in Figure 2.
