Refresh Registration
every __ seconds
The frequency with which the system informs the gatekeeper that it is active by
re-sending the IP address and aliases of the IP cards to the gatekeeper. 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 Collaboration Server’s Signaling Host within the
network. Up to five aliases can be defined for each Collaboration Server.
Note: When a gatekeeper is specified, at least one alias must be entered in the
table.
Additional aliases or prefixes may also be entered.
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)
• 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.
