Creating a trunk utilization report

Trunk utilization reports provide use data and statistics for toll-free numbers in near realtime. 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.
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.

To create a trunk utilization report:

Click Monitoring, click Voice Reports, then click Toll Free.

Control Center lists the toll-free reports you have access to.

Click Trunk Utilization.

Select the radio button for the type of trunk utilization report you want to create:
- Daily—shows the data you select for each day in the report's date range.
- Hourly—shows the data you select for each one-hour period in the report's date range.
- Monthly—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—shows the busiest hour of traffic each trunk group experienced over a 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.

Based on the type of report you select, Control Center shows options for the report.

Select how you want the report set up, then click Run.

Control Center builds the report. Based on the report type, use the table below to better understand the data in the report.
