Same, I didn't answer and no message. I tried to call back a couple of times and it is always busy. I am currently being harassed by a former "friend" that has posted my pic and phone number on Craigslist hookups so I am a little paranoid about who is calling my phone. Wondering if this may be some sort of Internet number that people can call you with so that you don't know it's them?
This number called, and she sounded automated, but then someone answered my questions about where she was calling from etc. She stated she was from a public service for insurance savings. Ug, should've alerted me there. She asked me what my insurance was and how many cars I had and then hung up. I assume that she realized I wasn't elderly and wouldn't give her any other info. So sad that these people prey on others.
