Is there any way you know that I could rerun the billing that was done on 1st of September without charging for the calls that have been generated since then in the month of August??
if there has been little / no activity on your system, then you delete all cc_invoice, cc_invoice_item, cc_receipt, cc_receipt_item, cc_billing_customer entry that have a date in the range of start/stop of your billing. then you update all your customer billing day to current day & rerun (and set the billing day back).
obviously, make a db backup first - just in case !
ideally, you even take this backup to another box, restore it, test the changes there, and then run your bills on the prod system !
I cant guarantee the above procedure will work 100% - however, I've used it several times in a test environment to test evolutions of the billing script.
kind regards
