Okay, I once received a phone call from this number and they DID leave a voice mail message. It was from the prosecutor's office in downtown Indianapolis.
I'm not sure who else would be able to use this or how, but that's what it was for me.
Got a call from this number 4 times a few days ago while at work. Both times I picked up a male named Greg responded saying he's from the something probation office looking for Phil.
I received a call from 317-660-2116, and i never answered it. But when you call the # back you get a recording that saying this is the investigating office. Please do not leave a message. WTH!!!!!. Investigate what. I haven't done anything. I think this is a debt collector
