CDR Auto Cleanup
By default, when the number of call logs reaches 200,000, the system will automatically delete the oldest call logs (relevant recordings are retained). You can change the maximum value, or you can also set the maximum preservation days. For more information, see Auto Cleanup Settings.
Regularly monitoring and cleaning up call logs can help in managing storage effectively and ensuring optimal system performance.
