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