Need to connect new phone service with existing jack in condo

[Dominus]

Hi

I am renting a room in a condo in a building of condos. My new Pacbell/SBC phone service is supposedly active. In my room, the phone jack is active but the line is that of a roommate.

Down in the garage is where the external phone lines meet the internal ones. I'm not sure if it's what people are calling an m-box or a 66 or a 110-block. I have taken pictures but I guess I can't attach them to this post. There is a long plastic rectangle for each unit. There are rows of dual slots going down this rectangle where phone wires are attached.

So all I have to do is become smart enough to connect my new activated phone service with the working line that goes to my jack.

Am I better off paying the phone company $150? It looks so simple. Can someone explain what I do or point me to a webpage or post here that explains it for dummies? I'm pretty tech savvy but never worked with phone stuff. I can't find instructions for this seemingly simple task. Any help would be appreciated.

Before you go monkeying with the block, try this simple thing at your jack. Swap the red and the yellow wire, and also swap the green and the black wire. This might be all you need to do. If this doesn't work out, put them back the way they were.

(If your wires aren't red/green/yellow/black, you will instead swap the orange with the blue, and swap the white/orange stripe with the white/blue stripe)

Repost if this worked, and we can help you some more.
