Indeed, if you refer to real time events then this is the way to go. 
However, many people (including our company) use CDRs as a fall back in 
case we don't have real-time billing data available. We use real time 
information for prepaid customers and stats, but we also crosscheck this 
data with CDRs periodically.

I agree that both approaches would be useful in many different scenarios 
for different users. It would be ideal if both approaches could be 
implemented.
