Chapter 2 New and Changed Information
Cisco Unified Communications Manager, Release 8.5(1)
Configuring the Trunk
Tip Configure the trunks in CAR for existing Cisco Unified Communications Manager system trunks. After
you add trunks to Cisco Unified Communications Manager Administration, configure the new trunks in
CAR. When trunks are deleted from the Cisco Unified Communications Manager system, the system
automatically removes the trunks (and any configuration settings that you specified) from CAR.
CAR uses the area code information to determine whether calls are local or long distance. You must
provide the Number of Ports information for each trunk to enable CAR to generate the Utilization
reports.
This section describes how to configure trunks in CAR.
Procedure
Step 1 Choose System > System Parameters > Trunk Configuration.
The Trunk Configuration window displays.
Note If you have not configured trunks in Cisco Unified Communications Manager Administration, a
message displays that indicates that you have not configured trunks for the system.
Note CAR uses the area code information to determine whether calls are local or long distance. For
8.5(1) release, the area code is not updated for all the trunks.
Step 2 In the Max No. of Ports field, enter the number of ports for each trunk that you want to configure. The
maximum number of ports range from 1 to 1000.
Note CAR uses the values that were provided for the trunk when it was added in Cisco Unified
Communications Manager Administration. Therefore, some trunks will already have a zero for
maximum number of ports, depending on the details that were specified when the trunk was
added in Cisco Unified Communications Manager Administration. CAR does not accept zero as
a value for the maximum number of ports; you may be prompted to change the maximum number
of ports for all trunks with a value of zero.
Step 3 To make the changes, click the Update button.
You can run reports in CAR on any or all of the configured trunks.
Configuring Trunk Utilization Reports
Only CAR administrators generate the Trunk Utilization report. This report calculates the utilization
reports for devices based on the duration of calls that passed through the devices.
You can generate this report on an hourly, daily, or monthly basis. The system calculates the utilization
of a trunk for each hour in the selected date range. For example, the system calculates the utilization of
a trunk between 11hrs-12hrs, using the formula, (Sum of the duration of calls that used the trunk in that
hour / (total seconds in an hour * maximum number of ports in a trunk * number of days between the
fromDate and toDate selected) * 100).
