    Greetings,

    I am getting flagged for using TLS 1.0 by PCI Compliance scans for one of my clients. We are using v15.5 SP3, which I thought uses TLS by default. Is there a way to disable the use of TLS 1.0 in favor of TLS 1.1 or 1.2?

    I don't have a test server to try this on but normally with nginx you would change the line in the nginx.conf:
    ssl_protocols TLSv1.2 TLSv1.1 TLSv1;
    and just remove the v1 and v1.1 items

    This line isn't in the conf file for 3cx. Also I don't know if it would break something in the system or not but you could try on a test server to add that line and start the server.
