According to another site this caller is political. I didn't recognize the number so I didn't answer--didn't stop ringing! Kept calling back one right after the other...I started counting rings after the first call ended and the next one began--50 rings total!! I answered and got silence...then a hang up!! It's bad enough that we get assaulted with the ads on TV but to invade our lives on our cell phones and home phones is just beyond the pale!
