MeetingPlace Express 2.0 (scheduled, reservationless, or ah-hoc modes) will combined with a MCU for video conference call. The video will be voice activated switched. The two talking people will see one another. If the three people start arguing at the same time(hehe) it switches all over the place.
MeetingPlace Express VT 2.0 (only supports ad hoc). Same - video switched. For an MCU you can go with the 3515 MCU or other MCU models.
The Continuous Presence means "all" the video participants can see everyone else. You can configure the layout also. (2x2 grid, 3x3 grid, etc.)
