My suggestion:

"When a forking proxy receives a non-2xx final response that it
  recognizes as terminating one or more early dialogs, it SHOULD generate
  and send a 199 response upstream for each such early dialog satisfying the
  following conditions:
  -- the proxy does not intend to forward the final response immediately
     (in accordance with rules for a forking proxy);
  -- the UAC has indicated support for the 199 response code;
  -- the proxy has not already received and forwarded a 199 response for
     that early dialogue."
