Have called several times, sounds like they listen, then hang up.

Got the same call 3 Times tonight 6:27, 7:27, 8:08 and never left a message.Caller ID shows Unavailable. My Guess is when you actually answer the phone then they know what time you are home, and they will start calling at that time to harass you. These times look like computer generated calls to me.

Strange number on caller ID. Where in the world is area code "180"??
