I got it at 5:30 in the morning. It's quite annoying but I looked it up and it does say it's the DePaul Hospital. Why would a hospital that I've never even heard of be calling me? Specially that early in the morning!
It is possible that somone is masking their real phone number, and having Depaul Hospital's phone nunber show instead for those of you that received such a phone call. That is the main number to the operator at the hospital.
