Caller appears to be scam artist - he can't even tell that he got an answering mach. Number shows as "invalid" so the caller would be assumed to be operating illegally. Call-screening just lets him go to nothing.
Have been receiving calls from 224-404-018, and the caller ID shows "Elk Grove VI, IL...I have no idea who this is! Has been calling all week...you'd think "they" would get the message when my answering machine picks up ... no one's going to answer their call...stays on the line a couple of minutes, then hangs up...IDIOT!!! Just leave me alone! I will NEVER answer the phone, especially if I don't rcognize the number. Morons!!
