Got a call from this number, answered and muted so they couldn't hear anything on my end. It was just dead air until the line clicked off. Likely an automated system that doesn't start playing the recording until it hears a voice.
I got a call from this number too. I answers it and muted it. Then I un-muted it and said, "hello? Can I help you?" No one answered and then the person on the other like just hung up.
