/mcpb) To update the area code for specific trunks, enter the area code for each trunk that you want to configure in the area code field for that trunk. Step 3 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 goes from 1 to 999. Note CAR uses the values that were provided for the trunk when it was added in Cisco Unified CM 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 CM 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 4 Click Update. You can run reports in CAR on any or all the configured trunks.
