3cx v15.5 (Elastix 5) give me this error when i try to do a Firewall Check
What is the exact build number of your PBX? You can see that on the Dashboard under the Information column next to the licence tab. Also do you face this issue only with the firewall checker?
Is this a new installation an upgrade or a restore from backup? What is the OS you installed the PBX on? h
