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.
Cisco recommends that you have knowledge of these topics:
The information in this document is based on Cisco CallManager Version
3.3 and later.
The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

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.
