Who called from 9287773222

Called and asked for me and wanted to know if this was a work number, then hung up.

Called, said hello but no answer from other end.  They hung up on me.  Tried to call back and got a recording saying the number is disconnected & no longer in service.  Strange!

Phone rang. I answered and said Hello. No response. I hung up.

I received another call with similar no response from 1 (217) 357-2969.
My number is on the national do not call list.
