Disconnected parties get a fast little chirp-chirp (sorta like the tone
you get from ISDN phones after a hook flash, except much higher in pitch,
and of shorter duration), followed by a click, then a non-breakable,
unusual dial tone.  Unfortunately, there's no way for the preempted
callers to know on whose end the preemtion took place, so the call is
generally not re-attempted for a while.

As a side-note, I just realized how much less I use Autovon now that
email is here!
