Fun with phones
Attempts to move my phone line into my new room unsuccessful. The little door labeled with my room number in the customer access box outside has "do not use 'nsi' shorted" written on it.
Attempts to move my phone line into Sarah's room, however, were successful.

The mess of wires to the left is the binding post box. When you order a phone line, the phone company will send it to one of the binding posts (numbered 1 through 30-something). If you wait long enough on hold, sometimes you can get someone at the phone company to tell you which binding post. Sometimes.
The smaller boxes to the right are supposed to be the customer access boxes. Each little door is labeled with a room number and has a test plug and some more posts. There are two cables (each with a pair of wires) coming out of each door area. One supposedly goes into the house and ends up at the phone jack in your room. The other ends up in the mass of wires in front of the binding post box. To connect your phone line to your room, you need to connect the pair of wires that corresponds with your room-box to the correct binding post.
Except it's never that simple. In this case, there's no line to my room coming out of the little door in the customer access box. I have a phone jack in my room, but absolutely no idea if or where it ends up in the mass of wires outside.
