SPAM and probably a scam too.

Received a call from this # and after a few second pause followed by a 'boop' sound, an automated voice came on the line and said "Hello". I waited and the automated voice said "Are you there?" and finally disconnected

Calls began yesterday. They just hang up, no message.

Called but left no message.

This number called me at dinner time. It was an automated voice. Trying to sell me a security system. Said someone gave my number to them. What a bunch of B.S.
