Who called from 3172498079

Called my work number. Did not leave a message. I picked up, but they did not say anything. Are you joking? Calling my work number.

Just got my second call from this number. Never leaves a voicemail. Not going to bother calling back.

Caller ID says Carmel, IN

Called today - no message.  I called back - and got the message "Number has been disconnected"

Called twice w/in the hour, but missed both calls, no VM. I am a Medical Student in Indianapolis.
