Whether or not its legal is irrelevant. It's trivial to do if your link to the PSTN is digital and you have a provider not filtering based on sent caller-id. It's kind of the PSTN version of the Internet's BCP-38 issue. All providers should be filtering based on "valid" caller-id...but so many don't do it, and the spoofing is nearly impossible to trace back to the origin, so those who do it can safely ignore other laws because they know they won't be caught.
