IMHO it's clear:

21.4.18 480 Temporarily Unavailable

  The callee's end system was contacted successfully but the callee is
  currently unavailable (for example, is not logged in, logged in but
  in a state that precludes communication with the callee, or has
  activated the "do not disturb" feature).

*is not logged in*. Not sure why most vendors cannot understand
something as easy as this.
