Good question.  If it is, Asterisk doesn't detect it -- the PBX doesn't
support Kewlstart-style disconnect notification.

The sequence I hear on the extension, when I plug in an analog phone, is the
click of the phone at the other end being hung up, followed immediately by a
* touchtone.  Then there's silence until I hang up.

Hmm...  I bet it has everything to do with not having 't' or 'T'
in the
dialplan -- asterisk is ignoring the tones because it's potentially a 
security problem.

At least that's my current working theory -- I am not sure if t/T listen ofr
all DTMF or just #, and I also don't know the direction of your call (PBX
->
* or * -> PBX).

-A.

I have a "t" in the dialplan, but not "T".  I could add a
"T" entry and see
if it'll help.  Currently what happens is Asterisk doesn't seem to
notice
the *, then it eventually goes to the "t" extension.  This is
undesirable
since "t" transfers to the receptionist, who then gets a dead call.

What puzzles me is it works fine if I dial *, but if I hang up instead and
the PBX sends *, Asterisk doesn't seem to get it.

PBX -> Asterisk.  I'm setting up Asterisk to replace an old voice mail
system.

Yes, in both cases.

Okay, the problem appears to be that I'm tone deaf. ;)

I finally thought to turn on debugging on the channel.  The PBX is sending
"D", not "*".  The programmer of the previous voice mail
system (whose
configuration I was cribbing from) seems to have made the same mistake.
