asterisk users - Oct 2006 - detecting the receivers voicemail

Hi,
 Is there any way asterisk can detect if the outgoing call is being received
by a user or it has been forwarded to his voicemail.
Actually my requirement is to proceed only if user picks up the phone
otherwise to hangup as soon as the call goes to voicemail.

Is there anyway to do this?

Thanks in advance.

Not really. Not unless you prompt the user to press a key and they have to do
within x amount of seconds.

If you wish to detect forwarding to voicemail (or another number) at the 
telco level (e.g. mobile phone or fixed lines) , it may be possible 
provided you're using ISDN and your telco provides the relevant information.
