A _long_ time ago someone published a list of dial codes buried in
asterisk that supposedly had some of these functions. Something like
*8# = call pickup, *73 = pstn call forwarding, *78 = pstn flash, etc.
(I just made up those codes, they aren't real, and I can't find
that list now.)

Does anyone have that list and is flash embedded in that? I'm thinking
it was.
