Option	Description
Encryption	Choose any of the following Encryption options:
	• Auto - When participants connect to a
	conference, the conference/Entry Queue
	encryption settings are automatically applied to
	the participant. For example, when a conference/
	Entry Queue is set to encryption the participant is
	also encrypted (if the flag in the MGC Manager
	ALLOW_ENCRYPT_IN_PARTY_LEVEL is set to
	YES).
	• On - enables encryption at the participant level (if
	the flag MGC Manager
	ALLOW_ENCRYPT_IN_PARTY_LEVEL is set to
	YES).
	• Off - disables encryption
	Note: Undefined participants are connected with the
	Participant Encryption option set to Auto, inheriting
	the Conference/Entry Queue encryption setting.
Number of	Indicates the number of channels used for the
Channel	connection.
	Select Auto to use the conference’s Line Rate
	setting. This is also the mode recommended for ATM
	connections.
	If the participant’s setting is different from the
	conference setting, select the appropriate number of
	channels.
AGC	The Auto Gain Control mechanism regulates noise
	and audio volume by keeping the received signal to
	all participants balanced. Different endpoints and
	phones produce different types of source noise and
	volume. The Auto Gain Control mechanism can be
	applied to all incoming audio streams prior to mixing,
	thereby dynamically changing the amplification of the
	input signal providing a constant output amplitude.
	Select this check box to enable Auto Gain Control
	(AGC) for the participant.
