Number shows on my phone as Greenwood Missouri. No one answers after holding for quite awhile

No message, no voice, just a dead line.  When trying to call the number back, there is just an answering machine with no information.

This number has called my land line multiple times. I finally answered and there's no one or nothing. So i call back and something or someone answers but just silence then a click.

Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.
