Table 4-3: Participant Dialog Page parameters

Option	Description
SIP	Select the SIP option if the participant is an SIP
	participant/SIP phone participant.
SIP Address	sip: [user name]@[domain]. Note that the SIP
	URI adheres to URI rules: no spaces or special
	characters such as commas, quotation marks,
	inverted tags and so forth either in the user name or
	in the domain part.
	[To compare to H.323, which uses the endpoint location for
	identifying the participant, in SIP participants can change
	locations but still be addressed as long as they
	continuously refresh their registrations with the proxy. The
	proxy forwards Invitees to their current location.
ISDN/Phone	Select the ISDN/Phone option if the participant is an
	ISDN participant or a telephone participant.
T1-CAS	Select the T1-CAS option if the Audio Only
	participant connects via a T1-CAS line and the MCU
	is configured to support T1-CAS lines in Audio Only
	and Video conferences.
Participant number	Type the participant’s phone number (including
	country and area codes when required) to be dialed
	by the MCU when connecting the participant to the
	conference. For video calls using several channels,
	add a semicolon (;) between numbers when several
	numbers are to be assigned to a participant (one per
	channel). For example, 9251222; 9251223; ….;xxxx
	(in aggregation mode).
	In order to support Bonding with specific switches
	you many need to add the pound key (#) symbol at
	the end of the dial-out number sequence. For
	example 9251222#.
VIP	Select this check box to assign the VIP status to a
	participant. A participant designated as VIP will be
	displayed with a special VIP icon to indicate
	participants that.
