CDR Analysis and Reporting (CAR) provides reporting capabilities for three levels of users:
Only administrators can generate Voice Messaging Utilization reports which come under the category of Device reports. Device reports track the load and performance of Cisco CallManager related devices, such as conference bridges, voicemail servers, and gateways. This document describes how to capture Voice Messaging Utilization reports from the CDR.
Note: The CAR Voice Messaging Utilization report only supports Cisco uOne, Unity, and Octel Voicemail gateways.

The Voice Messaging Utilization report provides an estimate of the maximum utilization percentage of the voice messaging devices for the period and not the exact utilization. For example, the system calculates the utilization of a voice messaging device between 11 hours and 12 hours by sampling the one-hour duration in five-minute samples. The system calculates the utilization for each five minutes as (number of calls in the five-minute interval that used the voice messaging devices * 100) / (maximum number of calls that the voice messaging devices can handle at any time). After calculating the utilization for each five-minute sample for the entire one-hour duration, the maximum utilization value that is found for that one hour displays in the report as the utilization for the time between 11 hours and 12 hours. Similarly, to get a utilization for the whole day, the whole day comprises samples of five minutes each, and maximum utilization gets calculated. You can examine the usage based on each hour of a day or on a specified number of days for each week or month. Reports generate for each voice messaging server.
This section describes how to generate, mail, or view Voice Messaging Utilization reports.
Log into the Cisco CallManager Administration page and choose Applications > Cisco CallManager Serviceability.
Choose Tools > CDR Analysis and Reporting > logon using the administrator username and password.
Note: Only CAR administrators can generate the Voice Messaging Utilization report.
Choose Device Reports > Voice Messaging > Utilization.
Choose a Voice Messaging Port or choose a Voice Messaging DN from the left-side panel.
Click the down arrow icon in order to select Voice Messaging DNs/Ports.
Enter the date range of the period for which you want to see call information and click the View Report button. If you want to mail the report, click the Send Report button.
Note: Ensure the date and time range does not exceed one month.
