Hi Bejoy,
As Java has mentioned you need to enable CDR's on all nodes within the cluster, can you confirm the following:
1. CDR's enabled on all nodes (Disabled by default) Can be enabled through Serviceability.
2. Log calls with zero duration is enabled (Disabled by default)
3. How does your billing server obtain the CDR's? - SOAP request or FTP/SFTP? most call logging / accounting solutions tend to use FTP/SFTP, such as our own.
If 1 and 2 are enabled then I have seen instances where the UCM stops sending CDR's via FTP/SFTP.
You can restart the process of transmitting and CDR's that have not been sent by:
Login to the Cisco Unified Serviceability screen, located in the drop down list.
From the menu, select Tools, Control Center - Network Services.
You should now see a list of all the services, find the section CDR Services. Restart the services in the following order:
- Cisco Database Layer Monitor (Depending on Cisco UCM version, you may not have this service)
- Cisco CDR Repository Manager
- Cisco CDR Agent
- Cisco CAR Scheduler (If sending CMR's)
Let me know how you get on.
Best Regards.
