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.
