Ring Back Test

I'm not to sure about weather or not this still works but back when i was in middle school i used to go up to the payphones and dial 991 then the last 4 digits of the phone. You then would hang up the phone then pick it back up and hang it up. After a few seconds the phone would start to ring.
It seems that in recent times this doesn't work anymore has the ring back number been changed or what?
