 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 RealPresence Collaboration
Server (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 RealPresence
Collaboration Server (RMX) system informs the gatekeeper that it is active. The RealPresence
Collaboration Server (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 RealPresence Collaboration Server (RMX) Signaling
Host within the network. Up to five aliases can be defined for each RealPresence Collaboration
Server (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.
Configure Ports
Settings in the Ports tab allow you to allocate specific ports in the firewall to multimedia conference calls.
The port range recommended by the Internet Assigned Numbers Authority (IANA) is 49152 to 65535. The
MCU uses this recommendation along with the number of licensed ports to calculate the port range.
