I think you'd find the guy at the other end to be in some phone pit in India. I got a call some time ago from an earnest "gentleman" who insisted that my Windows PC had issues that they'd detected, (via the ether, no doubt).
I asked them what my IP address was when they wanted remote access, but they couldn't tell me that. Wonder why not?
I told the fool that I'm a sysadmin, I don't use Windows, that all the Internet-exposed machines on my address were running Linux, and called him a scamming beef-eating son-of-a-bitch.
What joy I felt when he started yelling and cursing me as I hung up.
