Not really by design, but I have a brilliant method! My mom still has only a land line, and the cord is too short to reach the computer.

She got a fake virus alert on some skeezy website, and she immediately called the number, without checking with me.

They tried to talk her through enabling remote access so they could get in and do whatever horrible thing they intended, but they had to get her to identify her IP address and type a few commands first.

She tried going back and forth from the telephone to the computer in another room, and the scammer finally got angry and screamed at her, "can't you borrow a cellphone from one of your neighbours?" When she told him she couldn't, the man just hurled obscenities and hung up.

These guys really depend upon you being able to talk to them while typing and clicking.
