Who called from 4123871443

Multiple calls from this number as well as 412-387-1440. Calling both of my lines. I don't answer unknown calls, they never leave a message.

Same deal.  Called and did not leave a message.  I do not answer calls I don't know.

I'm in the 215 area code and I will never answer any calls that come in from area code 412 since they seem to be questionable. I get multiple calls from different numbers with 412 area code.
