We all know how a2b update the accounting which is after the call ends. Now I want to update account at a specified seconds (period).
For example If I have 3 simultaneuos user on a prepaid account, I can not use postpaid billing method for the accounting because I will be using single credit account for 3 users.

Is it possible to have a callback function that will check every seconds/specify period to update the billing (just to deduct the usage from actual credit)?
