Primary Gatekeeper
IP Address or

Server is used) or IP address.
MCU Prefix in
Gatekeeper Enter the string with which the MCU registers itself
with the gatekeeper.
The gatekeeper uses this string to identify the MCU
when forwarding calls to it.
H.323 endpoints use this number as the first part of
their dial-in string when dialing the MCU.
Aliases
Alias The alias by which the RMX’s Control Unit is identified
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 Select the type that defines the format in which the
card alias is sent to the gatekeeper.
• H.323 ID (alphanumeric ID)
• E.164 (0-9, * #)
• URL ID (URL style address)
• Transport ID (IP address: port number)
• Email ID (email address format)
• Party Number (identical to the E.164 format)
Note: Although all alias types are supported (with
H.323 and E.164 being the most common), the type to
be used depends on your gatekeeper’s capabilities.
