	• Up to 2 Mbps on each stream without affecting capacity
	• QCIF, CIF and 4CIF in the same conference without affecting capacity
	• VGA, SVGA, XGA (supported for presentation channel only)
Multi-view (Dual	Supports dual-screen video and data transmissions to endpoints supporting
Video)	two monitors using the H.239 standard or TANDBERG DuoVideo. One
	monitor receives the conference video image and the other screen displays a
