Hi, dear!
Welcome to our community!
Before that, whether the function is normal?
Please check the following items.
1. Check whether MCU resources are sufficient and whether resources are occupied by scheduled conferences.
2. Check whether the recording server is configured for the conference and whether recording is selected for the conference parameters.
3. Check the SMC partition policy configuration.
4. Check the SMC service area configuration.
Hope the answer can help you!
