  4. Solved Outbound calls : 403 forbidden Invalid Authentication

    I just upgraded my 3cx system to v18. It works for incoming calls but doesn't work on outbound calls. I get 403 forbidden call failed in my desk phone and with email, i see the error 403 Incorrect Authentication. If i revert back to my old version, it works fine. Any thought?
