[Asterisk-Users] PrePaid and IVR

[Brian West]

I see all these posts about wanting a script for prepaid setup... Have you
not even tried to look it up or put any effort forth?  If you stop and
think about it its not that hard.  It takes alot of error checking, alot
of testing to make sure it does correctly.  I did something simple today
just playing around.  I'm sure its buggy.. I'm sure it could be done
better... I'm sure some of you will giggle and point at it:


#!/usr/bin/perl
#
use Asterisk::AGI;
$AGI = new Asterisk::AGI;
my %input = $AGI->ReadParse();
my $try = 0;

while(length($pin) >= 3 || $try < 3) {
        $pin = $AGI->get_data("agent-pass", "10000", "4");
        if($pin eq "1234") {
                $AGI->exec('SetAccount',$pin);
                $AGI->stream_file('auth-thankyou');
                $AGI->exec('AbsoluteTimeout','10');
                $AGI->exec('Dial','ZAP/1/4238080');
                $AGI->hangup();
                exit(0);
        }
        $try++;
}
$AGI->stream_file('vm-goodbye');
$AGI->hangup();
exit(0);

You could also query one db for the card/pin and see how much time that
pin is worth.. then subtract the usage from that and use that value*60 for
AbsoluteTimeout

Now slap some DBI, better error checking and more logic/safeguards all of
which i'm going to be doing later on this week... but this is a very basic
concept of how it can be done.

Hint Hint.. you can round all the calls up to the next min by doing an sql
query (if using cdr_mysql)

select SUM(CEILING(billsec/60)) as used from cdr where accountcode='1234';

Just pass the accountcode == pin number

Really not that hard now is it?
