Caller ID useless?

In this day and age, how can the originator not be traced? And what is the point of these types of calls? What salesperson really believes I’ll buy anything from someone who calls me at 3 AM?!?!:eek:

Spoofing changes the digital tone codes set out that activate caller ID displays. I don’t know if the phone company/law enforcement has any way to defeat this.

I wonder if the origin isn’t a foreign country, explaining why the caller had such a heavy accent. Perhaps they forgot they were on the other side of the planet when they called.
