It might be unethical, if not illegal, but none-the-less very possible.  In 
many PBX type phone systems, the phone company accepts whatever number the 
phone system hands it with no verification.   A while back a misconfiguration 
in our phone system was causing the Caller ID numbers to appear as if they 
originated from one of the local hospitals.  A 3rd party or internet-based 
phone company could very easily do this, perhaps even provide it as a service 
so that when a call is placed, it randomly hands out number or, legitimately 
routes the call randomly through any of its assigned number pool.

That can't be true. It would be like the phone company is saying "Number 
spoofing is cool, as long as we're the ones doing it."

And it would be especially problematic if those random numbers translated back 
to legit numbers.

Has anyone heard of or dealt with a parent that reports that, because of 
serious, harassment-type problems with other people, that the phone company has 
them set up where random numbers are sent to caller ID's they call by the phone 
company when they make a call?  Sounds kinda far fetched to me thinking they 
can have their number blocked, but thought I'd check, could be I'm behind the 
times here.

Thanks!
