13     * Sets a flag that indicates that automatic error handling is enabled for this dialog (the
14     * default when automatic dialog support is enabled). This flag is set by default to TRUE when
15     * the Dialog is automatically created by the provider ( automatic dialog support is true) and
16     * set to FALSE by default when the Dialog is created under program control ( automatic dialog
17     * support is false). When this flag is set to true, the stack will automatically send the
18     * following errors :
19     *
20     * <ul>
21     * <li> <b>500 Request Out of Order </b> for in-dialog requests that arrive out of order.
22     * <li> <b>482 Loop Detected </b> When a loop is detected for merged INVITE requests.
23     * <li> <b>400 Bad request </b> when a REFER is sent without a matching refer-to dialog.
24     * </ul>
25     * If this flag is set to false, the stack will not drop out of sequence ACKs but will pass
26     * these up to the application for handling.
27     *
28     * This flag is automatically set to true if any of the the following conditions is true:
29     * <ul>
30     * <li>The Back To Back User Agent flag is enabled for the Dialog.</li>
31     * <li>The Automatic Dialog Support flag is enabled for the Dialog </li>
32     * </ul>
33     *
34     * This flag should only be set at the time of Dialog creation ( before the Dialog has seen its first
35     * request or response). If set subsequently, the behavior of the flag is undefined.
36     *
