We have 40+ Cisco IP Phone 7965, and an administrator in our office wants to know if he can access the database of any user's call history, e.g. wants to know what calls I made and received from any specific dates in the past. I was thinking it could be done through the Cisco Unified CM Administration web interface, but I don't know where to look at. Please let me know if this is possible.
Click on "CDR" then "Export CDR/CMR" and then check "CDR Records" and select the duration. You will get this CDR info in text format and after that you can open it using Notepad ++ and you can analyze it.
Read the documentation for CAR, or play with it, getting reports is not that hard
The maximum time data will be stored is 180 days, if you need to keep it for longer periods of time, you need to configure a billing server to hold the data, and also a 3rd party billing server as we only export the raw data.
The default is just 60 days for keeping records.
You can use any FTP server or you can get an actual 3rd party billing server with a pretty web interface for management to use.
Rather than exporting all the CDR, you can also just search for a certain extension under CDR->Search->By User/Phone Number. You can then enter their extension and press the "Add Phone Number" button and then set the time range.
