IP Address or 
Name
Enter either the gatekeeper’s host name (if a DNS 
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.
