The more I think about it, the more "call duration" makes sense as it is 
now.  If you want to force a shorter dialog lifetime, there is no need 
to duplicate this logic into check_fraud() -- you can already achieve it 
by setting custom $DLG_timeout values.

Ideally, we should be able to one or more stats [1].  And complete 
suggestions on how we can improve the existing ones are welcome.

Best regards,
