Who called from 5022544525

I got a call from the number 5022544525. I did not answer. I called back and recieved the standard "This number has been disconnected" message.  I found a different post on here talking about 502-254-4524 number and assumed it was the same problem. Anyone have problem from the number ending in a 5? Any idea what I can do to prevent future calls?

just now, hung up

best way to stop this stuff is to answer, wait two seconds and hang up
My incidence of receiving these type of calls had dropped dramatically.

Second called I've received from this number. I'm on the do not call list.

keeps calling no message no return number disconnected
