asterisk users - Mar 2010 - Asterisk and cellphone/GSM voicemailbox

Does Asterisk know when it hits a voicemailbox ?

When calling to a cell-phone or GSM, after some rings and no pickup you
arrive at a voicemailbox.

If Asterisk does not know it's a voicemailbox that has answered the
call, the voicemailbox will contain 60minutes of 'silence'. This is very
expensive 'silence'.

How to avoid this ?

You can avoid this is several ways... one of the ways I like best is to dial
with a macro that then requires the recipient to press 1 or some dtmf
confirmation to accept the call. Very good at avoiding voicemail, cell phone
service messages, etc.
