Who called from 6316295048

Called my DNC registered landline. No voicemail.
I used *67 to call back. "The number you have dialed is not in service."

called my home phone, only said hello, then hung up. I called the number back, and it did not connect to anything, i would like all to know that this must be some kind of scam.

Tried calling back as well and the number is invalid.  It is one of those fake phone number dialer.
