Comment Legitimate caller id spoofing (Score 1) 171
I've got a Google Voice number which forwards calls to my actual phone(s) based on rules I set up. One rule is "do you want to see the caller ID as the actual caller's, or as your Google Voice number?"
This is useful, but only because of the limited nature of caller id - it can only display one number. If it had slots for things like "original caller # and name" and "name of routing service", I wouldn't need to make that choice.
Also, it's unique in that *I* am deciding what information *I* want to see. I don't see any reason why someone should be able to call me and disguise their identity from me.
