Who called from 2055929960

I don't answer calls from number I don't know. Anyone else getting calls from this number?

No one was on the other line.  I just hung up after saying hello about 3 times.

Gastonia, NC

Call comes in and have not answered it but when I call it back it is a disconnected number

Answered the call, no one spoke.  Hard to tell if they hung up, were silent or what.  Hung up after saying hello a few times.

Received a call from this number at 9:20 A.M. this morning.  Phone only rang a couple of times.  No message left.
