After we have modified NTP and set timezone on cisco call manager. We have faced the below message:
Licensing Warnings:
System is operating on Invalid licenses. Call Manager service will go down after the grace period of 30 days expires. Please obtain valid license files and upload.

 

Appreciate your help.
