Is it possible to route a call trough a computer with cable internet, so that it looks like it came from your personal tell #? I was on my way to work, and i got a call on my cell phone. I didn't know who the hell it was, and after I got off I traced the # and it was placed from my business line in the basement of my house, and there was no one home at the time.... Also I have gotten some calls from a person who says that he was from at&t, at 3:00 A.M. in the morning!

If someone could help I would be very gratefull,

P.S. My systems have been compromised, is it true that you can hack a firewall like blackice defender with a properly named trojan?
