Who called from 8581748654

Left no message on machine.  ID said: "Name not found".  It sounds like a may be a scammer on a fishing expedition, looking for valid numbers.

Called, left no message. CID said "name unavailable". I'm form this area code and 174 is not a valid phone prefix so probably SPAM/SCAM. I called back just to confirm what I already knew, its not a valid #. BLOCKED!

Called:  ID said "Name Not Found".  It was a one-ringer, which meant it was a robocall of some kind.  I love those youtube videos of people getting even with unwanted telemarketers and other scammers.

I said hello. Then whoever it was or whatever it was just said Goodbye

Didn't answer this spoofed number.  Left no message on machine.  ID said: "Name not found".
