i am seeking help in creating feature in a2billing that will allow the card user to call in, enter pin#, and the system will playback the cash value remaining on the card. I have seen a few post out there explaing how to do this but involves a file called balance.php in the /var/libs/asterisk/agi-bin. i cannot find this file on my elastix box. running the last elastix build 1.5.2. does anyone have a solution to this. i have done something similiar with building what will be an option on an ivr that will once authenticated will take the card user directly to voucher system.
