I was on my office line when this numb showed up on my cell phone's Caller ID.  My phone shows it is from Minnesota but I don't have any further info.  I've had my cell number for about 6 months and the prior person had the phone number, "Heidi", has gotten a lot of collection calls.  Maybe this number, 952-242-1943, is trying to get ahold of "Heidi".  No voice msg was left.  Many of the other collection callers left voice msgs.
