(I'm not >sure whether the disconnected party got any kind of notification of why >he had suddenly gotten cut off.) Maybe someone who has used Autovon can >confirm this info and/or correct my details. 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! Pete Brown Mather AFB, CA
