It would have alerted me within 24 hours, which would have been 1/2 the cost.  
Of course I have an average erlong much lower than 5 over 24 hours.

How did they get in?  Did they guess a password to get in?  Was the password a 
good, complex password?  Or did they get in a different way?

That said (thinking out long), I might need to add a trigger for long-lived 
calls.  Even one long lived call to the wrong destination would cost 
significant money.  Maybe I should notify on any call longer than 3 hours 
during the day, 2 hours long at night?  I'll have to look through my CDRs to 
see how often this would trigger in my environment.
