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.
