asterisk users - Aug 2009 - How to detect if the call is being answered by Voice Mail?

Hi,

 

I am pretty new to Asterisk. I am trying to make sure some human being
answers the phone not the voice mail machine. How can I programmatically
identify that?

 

Here is my Sub:

 

sub DialPhysician {

        my ($self, $con, $PhysicianPhone, $call_id, $conv_id) = (@_);

 

        to_log($self, "Inside Dial Physician", 2);

 

        my $DocPhone = "1". $PhysicianPhone;

        to_log($self, "Values: $DocPhone, $call_id, $conv_id", 2);

 

        $self->agi->set_variable("STATE","NEXT");

       
$self->agi->set_variable("stat_vars","$call_id:$conv_id:$DocPhone");

        my $response
$self->agi->exec("Dial","Local/$DocPhone\@$out_context/n|20|g");

        my $CallStatus = $self->agi->get_variable("DIALSTATUS");

        my
$ANSWEREDTIME=$self->agi->get_variable("ANSWEREDTIME");

        to_log($self, "Physician Call Status: $CallStatus; ANSWEREDTIME:
$ANSWEREDTIME", 2);

 

        return 0;

}

 

Is this not the correct way to do this? Or Are there any other methods?

 

Thanks

The "best" way is to ask the caller to press a key to continue. Most 
answering machines have difficulty with this.

There are various "answering machine detection" schemes about. Google
for
Justin Newman and answering machine detection. He's put out some pretty 
cool tools in the past.
