Hi Nikki,
Have you looked at the available Call Detail Reporting (CDR) in CCM?
Understanding CDR Data
Call detail records (CDR) detail the called number, the number that placed the call, the date and time that the call was started, the time that it connected, and the time that it ended. Call management records (CMRs, or diagnostic records) detail the jitter, lost packets, the amount of data sent and received during the call, and latency. CDR data comprises CDRs and CMRs collectively. A single call can result in the generation of several CDRs and CMRs. Cisco CallManager records information regarding each call in CDRs and CMRs. CDRs and CMRs, known collectively as CDR data, serve as the basic information source for CAR.
You access CAR from the Tools menu of Cisco CallManager Serviceability after you install the CAR plugin as described in the "Installing the CDR Analysis and Reporting (CAR) Plugin" section in the Cisco CallManager Serviceability Administration Guide.
All CAR reports use CDR data. CAR processes CDRs at the scheduled time and frequency. By default, CDR data loads from midnight to 5 a.m. on a daily basis; however, you can set the loading time, interval, and duration as needed.
CAR retrieves information that is not only present in the CDRs and CMRs, but is required for various reports, from the Lightweight Directory Access Protocol (LDAP) and configuration information from CAR database (that CAR administrator can modify).
