Field	Description
H.323 Authentication	Click this check box to enable H.323 server
	authentication.
	Select this check box only if the authentication is
	enabled on the gatekeeper, to enable the
	Collaboration Server to register with the gatekeeper. If
	the authentication is enabled on the gatekeeper and
	disabled on the RMX, calls will fail to connect to the
	conferences.
	Leave this check box cleared if the authentication
	option is disabled on the gatekeeper.

User Name	Enter the user name the Collaboration Server will use
	to authenticate itself with the gatekeeper. This name
	must be defined in the gatekeeper.
Password	Enter the password the Collaboration Server will use
	to authenticate itself with the gatekeeper. This
	password must be defined in the gatekeeper.

These fields can contain up to 64 ASCII characters.

If the Authentication User Name and Authentication Password fields are left empty, the SIP Digest authentication request is rejected. For registration without authentication, the Collaboration Server must be registered as a trusted entity on the SIP server.
