    <p>Hello,</p>
    <p>what is exactly the problem? The header is not added if you
      enable:</p>

                I understood Alfonso's question to implicitly be: how
                can I add a dynamic and variable Reason header to
                outgoing CANCELs?<br>
                <br>
                Perhaps I was mistaken. But if I'm not, as far as I know
                there is no means of doing that. Right?<br>
