Field/Option	Description
Extension/ Identifier	This is the DTMF string sent to the recording or other
String	DTMF activated system; an outgoing DTMF
	operation initiated by the MCU. This is useful for
	identifying extensions associated with SIP users.
	Each type of recording system has a specific DTMF
	string structure, for example, when using the Prairie
	recording services.
User Defined fields	In any or all of the four User Defined fields, enter
1-4	general information for the participant, such as the
	participant’s email address, telephone number,
	company name, location, or any required information.
	The titles of the User Defined fields can be modified
	in the Database Manager ->Defaults ->User Defined
	Defaults and loaded to the MGC Manager
	application. For details, see Chapter 3.
	Note: The User Defined fields are displayed only if
	the Show User Defined Fields in Participant
	Parameters box is selected in the Database Manager
	->Defaults ->User Defined Defaults.
Broadcasting	You can control the volume of the audio transmitted
Volume/Listening	from the participant to the conference (broadcasting
Volume	volume), as well as the listening volume for the
	participant.
	To adjust the volume, move the slider. The volume
	scale is from 1 to 10, where 1 is the weakest and 10
	the strongest volume. The volume of each endpoint’s
	audio at connection time is set to 5. One movement
	of the volume slider increases or decreases the
	volume by one unit, equivalent to 3db.
Audio Only	When checked, indicates an Audio Only participant.
	This option is automatically selected and cannot be
	cancelled:
	• For T1-CAS participants
	• In Audio Look & Feel mode
	• When defining participants during Audio Only
	conference definition in the Conference
	Properties - Participants dialog box.
