We've been testing mod_nibblebill, it's a great module, cheers to the author! A couple questions regarding nibblebill: 1) We noticed that when an account is below the minimum balance and a call is attempted with that account, FS begins to connect the B leg for the call but then cancels the INVITE. Why is FS sending the INVITE for the B leg only to CANCEL it immediately, if the account is below the minimum balance? I would think it would just send the 404 immediately back to the user without sending any INVITEs to establish the B leg? 2) Any progress on implementing minimum billing increments (ie 60/60) ? Cheers, Gabe
