It does seem a tad random, but yes, it seems they are using it today. I have heard dispatches both automated and human, so I don't know if they are just taking particular calls to dispatch this way, or just picking them randomly. The testing of this over the past week has been pretty intensive, maybe that was the "final exam" test we were monitoring. Those stupid sirens and sounds before the dispatches have to go though. They are just plain stupid and annoying.
