```
    Create an error response for the request, for use with LimiterInstruction.reject(Response). The response must have a status code of 300-699. A provisional or success response would create a dialog, which cannot be supported as the overload control plugin is not capable of acting as a SIP user agent.
    
    Parameters:
    
    statusCode - the SIP status code for the response. This must be in the range 300-699.
    
    request - the incoming request being processed by the overload control plugin.
    
    Returns:
    
    a SIP response.
    
    Throws:
    
    IllegalArgumentException - if the status code is not in the range 300-699.
