May not be workable without a sufficiently high call rate 24/7. If you're a
small call center that usually has 3-4 calls per hour at 2AM, now long is "too
long without a call, time to get suspicious"?
Does your answer change if you're a 911 or suicide hotline?
(Yes, if you usually handle 50-60 calls per hour even at 2AM, a 5 minute
gap is probably suspicious. As I said, it depends highly on normal call rates)
