Well,

it's funny because here, now (Italy; Telecom Italia PSTN calling Wind
mobile), I do get the courtesy message saying that they're moving me to
voicemail, if I call myself from the office PBX to my mobile Wind
number, and the cellphone is switched off.

The question I would like to know more about is if there is some way to
discriminate between a courtesy message and a carbon-based voice
responder (aka 'a person' ;-).

Or is there some way to match a prerecorded voice file to the audio
stream coming in?

This could be great to do -easily- something like the voice commands
setups most cellphones offer: you say 'home', the voice file is matched,
and you get the call going.

Aldo
