I come home several times a week and find this number on my caller ID with no message. No biggee - I just delete it and go on. Today it called my cell phone while I am at work...and my cell is not listed to me, it's a government issued cell that's part of a very large phone service package. If they have traced me to get my G-phone number they are headed for some deep trouble.I'll be checking this one out with our IT and Telecom folks...messing with my hoime phone is bad enough, but don't hack onto a phone that is strictly for sensitive work purposes with a number that is not given out to the public.
