Every time I have to reboot the server that 3CX is running on, the system seems to go into trial mode (or some other reduced functionality mode). For example, none of the BLF buttons on the phone light-up and users can't transfer calls. To resolve it, I go to Activate License, enter the same license key that's already displayed in the Product Details, enter the Customer and Reseller Details and click Activate. The 3CX Phone System service restarts, all the BLF buttons light-up and everything starts working again. I've had to do this after every server reboot. Why is tha activation not sticking?
