Who called from 3124440342

No one on the other line.  Area code is Chicago.

I just got a call from this number also.

Phone call, I didn't know the number and they left no message.

Received a call.  Said left voice mail, picked it up and nothing no message left...A Skam?!

I know the powers that be on this site don't necessarily want notes added if you don't answer the call, but this is interesting:
I just received a call from 256.841.3099 [search this site for this number] which I already had marked as a 'Scam Caller' so I did not answer.    I have not received a call from the 256 number since 19 January 2016, and I answered it then because I am at work and this is a regional area code and prefix.
Back to today: I did not answer the 256 number - it went to voice mail.  IMMEDIATELY after it did, this 312 number called.
I let it go to voice mail, but no message was left.
So I am adding this because even though I did not answer and they left no message, it seems more than coincidental that the call immediately followed a call from known scam call number that I answered a few weeks ago.
