Help wanted with 3CX with Unifi Dream Machine

[Spottyjarl]

I've recently set up 3CX on a windows machine and have got it up and running however I can't get anything to work. When I scan the QR code with the app it'll work but never says connected it just says connecting in the top corner forever. I believe I have set up all the necessary port forwards but not 100% sure. I have also tried to connect an IP phone with no luck

Will try Bebian ISO and 3CX partner, would moving to a raspberry pi based system help?

Raspberry Pi would fall under the same category as the Debian ISO option: you avoid Windows, but if the firewall is ultimately the problem then you will still not pass the firewall checker.

Do what you said above and see how it goes, we can take it from there
