Hung up, left no message.  This number calls frequently.

Received a call from this number and didn't answer because not in my contacts. They did not leave a message.

A very professional-sounding woman (so professional, it sounded like a recording) called my work number, which I never give out for personal stuff. I actually asked her if she was a real person.  She sounded appropriately surprised, so I guess not.  Started asking about my current insurance, zip codes, and said an insurance agent was going to join us on the phone.  Then she asked for MY NAME.  I said, if you don't even know my name, then this is an unsolicited call, no thank you very much. and hung up.

Having no way to know if she was a legitimate caller or not, I am not about to give out personal information to someone who doesn't already know something about me. so CLICK!

Received call from this number. I answered, but I heard nothing for about 20 seconds. Hung up. Annoying...

Caller did not leave message.  I blocked future calls.
