[cisco-voip] billing problem!!! :(

[Costin Manda]

I am having a rather annoying problem. I have this billing software that
charges the users only for the calls that get through the first time. If ,
for some reason, a call gets rejected or does not complete, but it completes
on another hunted dial-peer, it does not bill.

Is there a way to tell Cisco to only send the start/stop-voip radius packet
only when the call actually was completed?

Thank you!
