"Oh. Hello. I was having a problem with my headset."
At this point I hung up because I have gotten this scam before. Very chipper young woman on the other end who pretends that you have stayed at a resort and then tries to get personal information out of you. If you say "Hello," then there's a pause and the person on the other end says what I quoted above, hang up. It's a phishing scam.
My on call work phone got called by this number. I answered (because I have to basically) on about the 3rd or 4th ring. I gave the greeting, paused, silent, thought I was too late at picking up, looked at the phone and it showed I was connected to the call. 8 seconds connected they disconnected with me.
