    Hi,
    Got quite stupid issue. I have 3CX. Firewall has opened ports 9000-9499. As recommended.
    7000-7499 are closed on firewall.
    I need to register internal extension and to do call outside internal network.
    Ext is registered but got silence during call.
    I see in conf: These ports need to use for outside calls to VOIP providers and external extensions.

    The question. How can I configure my extension as external?

    Best regards,

    You either need a gateway set up in 3cx to route calls over an analog line or you set up a voip provider to route through sip trunks (the cheaper and better way in my opinion).

    Once you register the trunk/gateway then set an outbound rule (3cx will guide you through this when you set up the gateway/provider) then you can call out from any extension.

    The ports that 3cx uses to place calls are set in the setting page (I forget whether it is in the general or advance settings) and should not normally be used.

    Did you run the firewall checker in 3cx to make sure everything is correct? You have to stop the phone service and tunnel and then run the firewall checker.

    Do that first and see if you missed something.
