Option	Description
Audio Alg.	When Siren7 (16, 24 or 32 bit) is available, select the
(cont.)	audio algorithm in the following order: Siren 7 (16),
	G.728, G.722, G.711, Siren7 16 bit and G.728
	algorithms are interchangeable, and a participant
	using either one will be fully connected when one of
	them is selected as the audio algorithm.
	If the conference line rate is higher than 128 Kbps, to
	achieve the best audio and video quality, select the
	audio algorithm in the following order: G.722.1 (32),
	G.722.1 (24), G.722 / G711.
	In Transcoding or Continuous Presence
	conferences, you can set the audio algorithm to any
	of the available audio algorithms as in a Video
	Switching conference.
	If set to "Auto", the system will try to connect the
	participants using the best possible audio algorithm
	selecting it in the order described for Video
	Switching conferences.
	The Audio algorithm 8 (G.729/G.723.1) is available in
	IP Only video or Audio Only (VOIP) conferences.
	In Audio Only conferences, the default algorithm is
	G.711 (56).
Video Session	Select the appropriate Video Session to set the
	video conference type:
	Video Switching - To set a conference in which all
	participants see the same picture (video). The
	current speaker is displayed in full screen on all the
	participants endpoints and the switching between
	participants is voice-activated; whenever a
	participant starts to speak, he or she becomes the
	conference speaker and is viewed on all screens.
	This conference type does not use the video card
	resources, therefore all participants in the
	conference must use the same line rate, and the
	same video settings. Up to 16 or 30 participants (if at
	least one Audio Bridge is set to 1/30) can take part in
	a Video Switching conference using the standard
	Audio card.
