This is a strange issue and need guidance on how I can troubleshoot this issue.
I enabled CDR Analysis and Reporting capabilities on Cisco UCM 5.1.
It has collected call details and reports like seeing call activity for a particular directory number for over a year.
Now it won't generate any new reports.
It generates "Error Code: 10021 - There are no matching records"
I haven't logged in for 3 months, so I don't know what the issue could be.
Is there something I can do and look at to fix this problem?
