New Automated call for Test Mode

I was testing a couple new sensors I installed today and when I went into test mode, I got my normal C.O.P.S. call. I was surprised when, instead of a human, it was an automated call confirming the signal was recieved! You could press 1 to confirm you're good to go or press 0 to speak with a human. I haven't tested in a while so I'm not sure when the change happened, or if this is now common knowledge, but I'm happy about this change. I was always a bit reluctant to do tests because I hated wasting the dispatcher's time. Now I feel liberated to test away at my leisure and I won't be a distraction for legitimate calls to C.O.P.S.!
