Audio Alg	This parameter determines the audio compression
	ratio. The higher the ratio, the more processing
	resources are required. Select the preferred audio
	algorithm for the type of conference you define:
	• 56(G711) 56(G711) – (default). In mixed network
	conferences this is the only available option and
	therefore the field is read-only.
	• 8(G729/G723.1) – Available only for VoIP (IP Only)
	conferences.
	Note: When the VTX 1000 check box is selected, the
	system automatically uses the G.722.7 algorithm for the
	connection between the endpoint and the conference.
Roll Call	The Roll Call feature of the IVR Message Service is
	used to record participants names and to play them
	back when participants enter or leave a conference.
	The chairperson can request the system to play the
	names of all connected conference participants at any
	time during the conference.
	To enable this option, the Roll Call option and fields
	must be enabled in the IVR Service assigned to the
	conference.
	Note: If the Roll Call option is disabled for the
	conference but enabled in the assigned IVR Service,
	the participant name is still recorded since the Roll Call
	can be enabled by the chairperson during the On Going
	Conference.
