hmmm...

RPI has its own internal phone system called the IBX (probably most
schools have their own phone system these days).  In it's infinite
wisdome, RPI decided to force all the students to have a phone in
their rooms and pay for it if they wanted it or not.  Well, I was
bored one day so I decided to play with it a bit.  Turns out there are
some fun things to do... the obvious one is to forward one phone to
another and then the second to the first.  The computer is pretty
smart, though and won't let you do that.

So, what you do is forward them to each other through an outside line!
You forward to 9-276-1234 and 9-276-4321, say.  The amusing side
effect is that each iteration of forwarding takes another two lines of
RPI's trunk into the Troy phone switch.  You can sit and listen to
them click in and the noise get louder and louder...after about 20
minutes, I got a busy signal and it dropped all the trunks.  My best
guess is that I actually used up all the available lines into RPI for
a little bit there.
