My machine started to take an answer: "... how are you today?.... Are you there?" Rookie scammer wasn't on the line when the machine requested a message.
I received a call from this number, but let it roll over to voicemail since I didn't recognize it. Caller didn't leave a message. The number is now blocked.
Caller ID says "Omaha NE". I pick up. I am silent. Nothing on their end either. After a moment they disconnect the call.
I call back after business hours (using *67 to block my number). Their outgoing message appears to be a pretty good computer generated male voice. I hear, "Hello. None of our representatives are available right now. If you received a call from this number, we should contact you within the next day. If you believe you received this call by error, please, press 1 to be added to our Do-Not-Call list." (I never do this as it can actually make things worse)
Note the failure to identify themselves. A computer generated voice makes me doubt their skill with English. So they spoof their caller ID, and fail to identify themselves. Smells like a SCAM.
