Chapter 2 - Defining Standard Audio Only Conferences and Reservations

Table 2-11: ISDN/ATM/MPI/T1-CAS Participant - Advanced (Continued)

Field/Option	Description
Recording	Designate the ISDN/T1-CAS participant as an audio
	recording port connected to an external recording device:
	Select one of the following:
	• None – The participant is not connected to an external
	recording device.
	• Dial up – The participant is used as the recording port
	to an external device.
	For more details, Chapter 8, “Recording”.
Encryption	Media information can be encrypted using an AES 128
	algorithm. The Encryption options are affected by the
	settings of the participant level flag in the system.cfg. For
	Audio Only participants connecting to an Audio Only
	conference with mixed networks, Auto is automatically
	selected. It implies the conference encryption setting
	(encrypted/non-encrypted)is applied to the participant.
	Audio Only ISDN/T1-CAS participants cannot be
	encrypted, because encryption is not part of the ISDN/T1-
	CAS protocol, and therefore, in this mode the participant
	can only connect as a standard participant to non-
	encrypted conferences.
AGC	The Auto Gain Control (AGC) mechanism regulates audio
	noise and volume by balancing the received signal to all
	participants. AGC can be applied to all incoming audio
	streams prior to mixing, thereby dynamically adjusting the
	amplification of the input signal.
	AGC is automatically enabled for all participants. Clear this
	check box to disable this option for the participant.
Save Participant/	These check boxes are the same as the check boxes that
Participant Linked	appear in the Properties Identification dialog box. For more
	information, see the description of the “Save Participant”
	parameter Table 2-10 on page 2-52.
