    Do you even need STUN on 3CX, maybe not. Do you use a VoIP provider or just a gateway? Do you have remote extensions?

    Run the 3CX firewall checker, see what results you get. Try to correct for any errors that show up. Might be a port forwarding issue, or router incompatibility.

    What is the actual problem that you think involves STUN? It looks like an extension is terminating the call.

    I use voip provider
    Running the 3cx firewall checker it tells me that works but with translation...but I don't know way, i have configured in the windows 2008 routing and remote access to map statically those ports...

    What make/model router are you using?
