Table 5-2: Gatekeeper Parameters (continues on pages 49 to 51)
Parameter Description
Third Gatekeeper IP Address
[GatekeeperIP]
Or
[GatekeeperIP = IP,ID]
IP address (or domain name) of the second redundant Gatekeeper you are using.
Enter the IP address in dotted format notation, for example 192.10.1.255.
Note 1: This parameter is available only if you select Yes in the Gatekeeper
Redundancy field.
Note 2: When using a domain name, you must enter a Primary DNS server, or
alternatively define this name in the ‘Internal DNS Table’.
ini file note 1: The IP address of the second redundant Gatekeeper is defined by the
third repetition of the ini file parameter GatekeeperIP.
ini file note 2: Use this parameter to define the ID of the second redundant Gatekeeper:
Gatekeeper = IP,ID
Third Gatekeeper ID
[GatekeeperIP]
String used to identify the second redundant Gatekeeper.
Used in Registration Request (RRQ messages).
The default value is an empty string.
Note: This parameter is available only if you select Yes in the Gatekeeper Redundancy
field.
ini file note: The ID of the second redundant Gatekeeper is defined by the third
repetition of the ini file parameter GatekeeperIP:
Gatekeeper = IP,ID
UseRedundantGKOnRRJ
[Use Redundant Gatekeeper
on RRJ]
No [0] = Do not switch to redundant Gatekeeper after an RRJ message is received
(default).
Yes [1] = Switch to redundant Gatekeeper after a RRJ message is received.
Fallback to Internal Routing
[IsFallbackUsed]
No [0] = Gateway fallback is not used (default).
Yes [1] = Internal Tel to IP Routing table is used when Gatekeepers are not available.
When the gateway falls back to the internal Tel to IP Routing table, the gateway
continues scanning for the Gatekeeper. When the gateway finds an active Gatekeeper, it
switches from internal routing back to Gatekeeper routing.
PreferRouteTable
[Prefer Routing Table]
Determines if the local routing tables take precedence over a Gatekeeper for routing
calls.
No [0] = Only Gatekeeper is used to route calls (default).
Yes [1] = The gateway checks the 'Destination IP Address' field in the 'Tel to IP
Routing' table for a match with the outgoing call and the 'Source IP Address' field in the
'IP to Hunt Group Routing' table for a match with the incoming call. Only if a match is not
found, a Gatekeeper is used.
Applicable only if Gatekeeper is used (IsGateKeeperUsed = 1).
Enable RAI
[EnableRAI]
Disable [0] = Disable RAI (Resource Available Indication) service (default).
Enable [1] = Enable RAI service.
If RAI is enabled, a message indicating “almost out of resources” is sent to the
Gatekeeper and an SNMP ‘acBoardCallResourcesAlarm’ Alarm Trap is sent if gateway
resources fall below a predefined (configurable) threshold.
RAI High Threshold
[RAIHighThreshold]
High Threshold (in percentage) that defines the gateway‘s busy endpoints.
The range is 0 to 100.
The default value is 90%.
When the percentage of the gateway‘s busy endpoints exceeds the value configured in
High Threshold, the gateway sends RAI message with "almostOutOfResources = TRUE"
and an SNMP ‘acBoardCallResourcesAlarm’ Alarm Trap with a ‘major’ Alarm Status.
Note: The gateway’s available Resources are calculated by dividing the number of busy
endpoints by the total number of available gateway endpoints.
RAI Low Threshold
[RAILowThreshold]
Low Threshold (in percentage) that defines the gateway‘s busy endpoints.
The range is 0 to 100.
The default value is 90%.
When the percentage of the gateway’s busy endpoints falls below the value defined in
Low Threshold, the gateway sends RAI message with "almostOutOfResources =
FALSE" and an SNMP ‘acBoardCallResourcesAlarm’ Alarm Trap with a ‘cleared’ Alarm
Status.
RAI Loop Time
[RAILoopTime]
Time interval (in seconds) that the gateway checks for resource availability.
The default is 10 seconds.
