Thank you!!! They call my house phone number which I have never used. It is just included in my cable bundle. I leave it plugged in in case a reverse 911 is used in the case of a wild fire (I live in Southern CA in an area that is very prone to wild fires and the possibility to know when evacuation orders are given). Thanks again for the info. Just wanted to make sure it wasn't an old friend that got my number (which would be interesting since I don't even know it by heart).
