New Gatekeeper Commands

This release introduces a new command for the gatekeeper configuration that causes retention of call history and enables you to specify the number of records to be kept in the history table.

In gatekeeper configuration mode, enter: 

gatekeeper(config)# call-history max-size number

The number argument in this syntax can be any number from 0 to 1200. The default is 15. This represents the maximum number of records of old calls to be stored and available for display.

To display the historical information, enter the following command on the gatekeeper: 

gatekeeper# show gatekeeper calls history

This command has been modified with the addition of the history keyword. This keyword was added to display call history information along with internal error codes at the gatekeeper. The number of disconnected calls displayed in response to this command is the number value specified in the call-history max-size number command. Use of this max-size number helps to reduce excessive CPU usage in the storage and reporting of this information.

Verifying IEC Options

You can use show command output to display IEC option configuration, to verify that the feature is working, and to display IEC counter information.

Prerequisites

Before you can display IEC counter information, you must configure voice statistics settings.

SUMMARY STEPS

  1. enable
  2. voice statistics type iec
  3. voice statistics max-storage-duration {day number-of-days | hour number-of-hours | minute number-of-minutes}
  4. voice statistics time-range periodic interval-length [start hh:mm] [end hh:mm] [days-of-week days]
  5. voice statistics time-range since-reset

DETAILED STEPS

Command or Action Purpose

1.

enable

Example: 

 Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

2.

voice statistics type iec

Example: 

 Router# voice statistics type iec

(Optional) Configures the collection of IEC statistics.

3.

voice statistics max-storage-duration {day number-of-days| hour number-of-hours | minute number-of-minutes}

Example: 


 Router# voice statistics max-storage-duration day 1

(Optional) Configures how long interval counters are kept for display.

  • If you want to display counters for past intervals, you must configure a storage duration for expired counters. Otherwise, once the interval has expired, the counters are no longer available.

4.

voice statistics time-range periodic interval-length [start hh:mm] [end hh:mm] [days-of-week days]

Example: 


 Router# voice statistics time-range periodic 30minutes

(Optional) Specifies IEC collection intervals.

  • The interval-length argument takes one of the following values:
    • 5minutes
    • 15minutes
    • 30minutes
    • 60minutes
    • 1day
  • The range for hh:mm is 00:00 to 23:59. The default for the start keyword is 00:00. The default for the end keyword is 00:00.

 Router# voice statistics time-range since-reset

(Optional) Enables the collection of call statistics information accumulated since the last resetting of IEC counters.

Displaying IEC Options

Perform this task to verify that the Cisco VoIP Internal Error Codes feature is working.

SUMMARY STEPS

  1. enable
  2. show running-config
  3. show voice cause-code category-q850
  4. show voice iec description string
  5. show voice statistics iec {interval number | since-reboot | since-reset}
  6. clear voice statistics iec
