Not sure this is an issue in Asterisk itself, but filing here for topic.

It seems that when people call and hangup when they get "the machine", a short voicemail with a few seconds of dial tone is left.

This shouldn't be happening, as the loop disconnect when the caller hangs up should disconnect us. It also doesn't reproduce when I try it, at least consistently.
