3CX Product Status Suddenly change to Activation Fail

[Microbiz]

Hello,

Hope you are all doing well, our client experience an issue were they weren't able to received any incoming call from 2 SIP provider. Upon checking the system, we noticed that the product status change to Activation Fail. We initiate the Refresh License Key Information and the system were back to normal and were able to received incoming call from 2 SIP Provider. We would like to ask for an advice on why these error suddenly occur and on how to prevent this from happening again since the system is use as the 911 emergency response. Our client's system were running smoothly since September of last year. Kindly refer below information of existing system. Thank you

Product: Professional Annual
Version Number:18.0 (Build 418)
Number of Simultaneous Calls: 4

Update 5 is a couple versions behind but it was the version required to activate after last year's changes. You could try updating to the latest. Otherwise is there anything in the event log? It should be checking periodically.

IIRC there is a clause in the 3CX license prohibiting it being used for an emergency/911 PBX...
