  from x.25 hacking history

In the late 1980's hackers stumbled onto a packet network
owned and maintained by a large facilities maintenance
company.  This particular network had a huge flaw in its
setup.  It connected all calls placed through it as if they
were placed with an NUI.  This allowed hackers to place calls
to addresses that refused collect connections on networks
around the world.  This became a popular method for hackers
to access underground chat systems in Europe.
