Exploring a trunk utilization report

Trunk utilization reports provide use data and statistics for toll-free numbers in near realtime. The system collects calls as they come in from the switch and allows you to create reports on toll-free traffic based on the call detail record. With these reports, you can better manage your toll-free use.

You can review your use by toll-free number or terminating address; select from two reports:
 

  • Statistical reports—use totals by toll-free number on a monthly, weekly, daily, or hourly basis. This report displays a list of toll-free numbers, followed by use information for each number. Statistical data is aggregated, summary data and it's kept for 40 days.

  • Ring-to reports—use totals by terminating address on a monthly, weekly, daily, or hourly basis. This report displays a list of trunks and switched-terminating addresses by toll-free number, followed by use information. Data is kept for eight days. 

With trunk utilization reports, your call record use statistics are broken out by daily, hourly, monthly, weekly, and busy hour.
 

  • Daily screen—shows the data you selected on the Trunk Group Statistics Report Criteria screen for each day in the report's date range.

  • Hourly screen—shows the data you selected on the Trunk Group Statistics Report Criteria screen for each one-hour period in the report's date range.

  • Monthly screen—shows the Busy Hour and Blocked Call data for the selected trunk group(s). For each month, in the selected time period, this report shows the busiest traffic hour, the date of the busiest hour, CCS information, and the total number of blocked calls.

  • Busy Hour screen—shows the busiest hour of traffic each trunk group experienced over the specified date range. This report tells you how many calls traveled over each trunk and how many calls were blocked due to traffic volume. It also includes recommendations for total channels needed to handle peak traffic loads.

The statistics your trunk utilization report contains are selected before the report is generated. As a result, you may not see all the fields listed below in your report.
