    it appears that you may not have the ports open correctly. Does your router have a log option for packets that it is dropping?

    Try putting the PC running 3CX on DMZ, see if it works, then go back and "revisit" the port forwarding (and other) options.

    I haven't seen other ports mentioned before in the server, log when doing a STUN test, it all happens over one port. The 3CX firewall test does check all ports.
