H.323 User's Manual
Description
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.
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.
Time interval (in seconds) that the gateway checks for resource availability.
The default is 10 seconds.
Disable [0] = Disabled (default).
Enable [1] = Enables the H.323 pre-granted ARQ mechanism.
If enabled, when an endpoint registers with a Gatekeeper, the Gatekeeper can
pre-grant admission requests to that endpoint, enabling it to establish calls without
applying to the Gatekeeper for permission, thereby reducing call setup time.
Gateway registration encoding type. This defines the encoding type of the phone
numbers that is used when the gateway registers these numbers with a
Gatekeeper. You can select:
E.164 [0] (default)
H323-ID [1]
E.164 and H323-ID [2]
NPI/TON from Table [3]
NPI/TON and H323-ID [4]
For detailed information on the available methods the Mediant 1000 gateway
registers with a Gatekeeper, refer to Section
For detailed information on the Registration Prefixes Table, refer to Section
on page 112.
No [0] = Gateway registers and acts as a standard gateway (default).
Yes [1] = Gateway registers as an H.323 terminal with multiple aliases (up to 24).
In all gateway messages, the terminal type value is set to terminal.
Enables / disables the automatic Gatekeeper discovery mechanism.
Disable [0] = Disabled (default).
Enable [1] = Enabled.
Note: When Automatic Discovery is enabled, the redundant Gatekeeper
mechanism is disabled.
The IP address to which a Gatekeeper Request (GRQ) is sent. Normally, this is a
Multicast address used to distribute the request to a large number of known
Gatekeepers.
When not configured or configured to 0, the well-known Discovery Multicast
Address (224.0.1.41) is used.
Time in seconds between registrations to the Gatekeeper.
The default value is 180. The valid range is 10 to 2000000.
Note: This setting must match the configuration settings on your Gatekeeper.
