Solved windows Firewall Hell

[VictorC]

Hello all, I'm having a heck of a time getting Windows firewall to let all the 3cx traffic thru. Every time I turn it on the softphone app on clients systems loose connection. Does any have all the ports that need to be forwarded?

If the machine is dedicated to the phone system (which is should be) then the windows firewall should remain off to prevent it from interfering with traffic. Also un-install any antivirus software installed on the machine.

The fire checker was fine. It always pasted.. The problem was the Softphone on work stations would go offline. I finally fixed it by just opening all the sip ports. I thought 3cx added them on install but I guess not in this case at least..
