Contingency Plan

There is no absolute safety. Make a contingency plan for your PBX.

If an attacker successfully forced your PBX to fail, you should have a contingency plan for your PBX.

Event Center

To get informed of the events that occur to your PBX, you need to configure Event Center on the PBX. Enable event notifications and add contacts to receive the notifications by email or phone number.

Schedule Auto Backup

Set auto backup on the PBX. If the PBX cannot work, you can reset the PBX, and restore the PBX configurations from the backup file.
