Who called from 4055366799

Phone call from this number, asked to speak to me or my wife be last name.Identified myself, and they immediately hung up.

Just got a call from this number. They hung up when I said hello

I received a call from this number I said hello & they hung up.

Same here. Got a call earlier from this number, they hung up when I answered. They called just a minute ago asked for me by name and then hung up. The number isn't valid when I call it back. What is up?

The same thing happens to me all the time.  I usually get a message on my machine once a day, which is just dial tone.  Never have a person on the line.  And when I answer the phone they just hang up.  Twice today.  Been going on for years.
