Is it legal for a person who receives a telephone call, to trace that phone call? For example, ‘Cardmember Services’ (the ‘Rachel’ or ‘Heather’ or ‘Anne’ calls) displays spoofed numbers on the Caller ID. Is there commercially available software that can be bought, that will trace the call back to its real origin (actual phone number and address)?
Tracing a call is a common device in fiction, where the Heroic Hacker finds the Bad Guy by tracing the call. Can this happen IRL?
