○ MCU Prefix in Gatekeeper Enter the number that the Network Service registers with in the
gatekeeper. H.323 endpoints use this number as the first part of their dial-in string when
dialing the MCU. Note that when you use PathNavigator SE200, this prefix automatically
registers with the gatekeeper. When another gatekeeper is used, this prefix must also be
defined in the gatekeeper.
○ Register as Gateway Select this option if you want to use the RMX unit as a gateway, for
example, when you are using an alternate gatekeeper.
○ Refresh Registration every __ seconds Specify an interval of time that the RMX system
informs the gatekeeper that it is active. The RMX system re-sends 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. Polycom recommends using default settings. This is a re-registration and not a keep-
alive operation – an alternate gatekeeper address may be returned.
○ Aliases You can specify an alias and a type.
○ Alias Enter an alias that identifies the RMX’s Signaling Host within the network. Up to five
aliases can be defined for each RMX.
Note: Enter a Prefix for Each Gatekeeper
When you specify a gatekeeper, you must enter at least one prefix or alias in the table.
○ Type The type defines the format in which the card’s alias is sent to the gatekeeper. You can
specify the following types of alias:
» H.323 ID (alphanumeric ID)
» E.164 (digits 0-9, * and #)
» Email ID (email address format, for example, [e-mail])
» Participant Number (digits 0 to 9, *, and #)
Admin Tip: Using Alias Types
Although all alias types are supported, the type of alias you use depends on the gatekeeper’s
capabilities.
