I posted this to the OTRS user list initially, but maybe the dev list is a better fit.

I'm planning to customize our ticket escalation criteria a bit.   This sysconfig setting looks like exactly what I want.

I'm trying to adapt some of examples here, but my code is being bypassed (though I see the setting in sysconfig).  Does anybody have a working example?
