    Port Forwarding is setup

    In the settings - network - public IP - STUN Server under the entry

    STUN Disabled (Not Supported) does this mean STUN is not supported

    What is the down side if I enable it

    The static Public IP will not take a FQDN and if I have an Internet Service with a Dynamic Public IP which changes - so when it changes what will happen

    I have to assume that it means that in V14, STUN is not considered necessary as you are expected to have a static Public IP.

    STUN is used to determine that type of NAT you are behind and your public IP. If calls to a provider use an IP that you datafilled, but has since changed, then external calls will not work properly. If 3CX relies on a STUN server to determine the current public IP, then it would be kept up to date, if, and when it changed.

    I'm assuming that you will have issues as you had previously, no audio, or no calls at all.

    Thanks for the information.

    I will enable the STUN Service since there does not seem to be a down side
