Who called from 2241145567

I just got a call on my cell phone from this number.  no message was left.  I don't know anyone from that Illinois area code.  Think I'll just block it.

I also received a call from the number on my mobile number.  I did not answer because I did not recognize the number.

two calls within 90 minutes today. left no message-blocking number now.

Ditto.  I'm in the Pittsburgh area.  Call came in at 11:10 AM.  no message left.

2 calls in less than 90 seconds. Didn't answer, no message. I have a PGH cell phone #, and it looks like another person on here does as well. Interesting coincidence.
