asterisk users - Feb 2006 - courtesy message calling mobile phones

Hi everybody.

Just noticed that when calling a mobile phone, Asterisk doesn't bridge
the voice message by telco if mobile is unreachable, but keeps on
ringing till it receives a hangup signal. I think this is due to the
fact that the message is played without the call has been answered, but
I'm wondering if there's some way to let Asterisk realize it. All I see
in the CLI is the line "PROGRESS with cause code 0 received".

Thank you,

_fangi_

Can you explain this?
What country?
In this case it's not asterisk but the telco that has to do the Answer.
To every mobile? or just that provider?

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
