before you call t_relay you set no-answer timeout to be a small value (a
few seconds) so that you are able to try the next gw as soon as
possible.  if your gw is alive, it will give you immediately a 1xx
response, which you process in on_reply route.  if you get 408 without
having seen 1xx, you can defunct the gw in failure route.
