Table 14	Default IP Service – Conferencing – Gatekeeper Parameters
(Continued)
Field		Description
Refresh		The frequency with which the system informs the
Registration		gatekeeper that it is active by re-sending the IP
every __		address and aliases of the IP cards to the gatekeeper.
seconds		If the IP card does not register within the defined time
		interval, the gatekeeper will not refer calls to this IP
		card until it re-registers. If set to 0, re-registration is
		disabled.
		Note:
		• It is recommended to use default settings.
		• This is a re-registration and not a ‘keep alive’
		operation – an alternate gatekeeper address may
		be returned.
Aliases:
Alias		The alias that identifies the RMX’s Signaling Host
		within the network. Up to five aliases can be defined
		for each RMX.
		Note: When a gatekeeper is specified, at least one
		prefix or alias must be entered in the table.
Type		The type defines the format in which the card’s alias is
		sent to the gatekeeper. Each alias can be of a different
		type:
		• H.323 ID (alphanumeric ID)
		• E.164 (digits 0-9, * and #)
		• Email ID (email address format,
		e.g. abc@example.com)
		• Participant Number (digits 0-9, * and #)
		Note: Although all types are supported, the type of
		alias to be used depends on the gatekeeper’s
		capabilities.
