The trigger-name argumentcan be one of the following:
•cpu-5sec—CPU utilization in the last 5 seconds.
•cpu-avg—Average CPU utilization.
•io-mem—I/O memory utilization.
•proc-mem—Processor memory utilization.
•total-calls—Total number of calls.
•total-mem—Total memory utilization.
Value of low threshold: Range is from 1 to 100% for the utilization triggers; 1 to 10000 calls for the total-calls.
Value of high threshold: Range is from 1 to 100% for the utilization triggers; 1 to 10000 calls for the total-calls.
(Optional) Busy out the T1/E1 channels if the resource is not available.
(Optional) Applies call treatment from the session application if the resource is not available.
The default is busyout and treatment for global resource triggers.
This command was introduced.
The command was integrated into Cisco IOS Release 12.2(4)T. Support for the Cisco AS5300, Cisco AS5350, and Cisco AS5400 is not included in this release.
This command was implemented on the Cisco AS5850.
This command was implemented on the Cisco 1750 and Cisco 1751 routers. Support for other Cisco platforms is not included in this release
This command was integrated into Cisco IOS Release 12.2(8)T and implemented on Cisco 7200 series routers. Support for the Cisco AS5300, Cisco AS5350, Cisco AS5400, and Cisco AS5850 is not included in this release.
This command was implemented on the Cisco AS5300, Cisco AS5350, Cisco AS5400, and Cisco AS5800 in this release.
Use this command to enable a trigger and define associated parameters to allow or disallow new calls on the router. Action is enabled when the trigger value goes above the value specified by the high keyword and is disabled when the trigger drops below the value specified by the low keyword.
You can configure these triggers to calculate Resource Availability Indicator (RAI) information. An RAI is forwarded to a gatekeeper so that it can make call admission decisions. You can configure a trigger that is global to a router or is specific to an interface.
The following example shows how to busy out the total calls when a low of 5 or a high of 5000 is reached:
call threshold global total-calls low 5 high 5000 busyout
The following example shows how to busy out the average CPU utilization if a low of 5 percent or a high of 65 percent is reached:
call threshold global cpu-avg low 5 high 65 busyout
call threshold (interface)
Enables interface resources of a gateway.
call threshold poll-interval
Enables a polling interval threshold for CPU or memory.
clear call threshold
Clears enabled triggers and their associated parameters.
show call threshold
Displays enabled triggers, current values for configured triggers, and number of API calls that were made to global and interface resources.

CUCM Database Replication is an area in which Cisco customers and
partners have asked for more in-depth training in being able to properly
assess a replication problem and potentially resolve an issue without
