I'm moving my router and I couldn't find any longer phone cables. I spotted a wall phone socket that was a lot closer so I decided to plug the filter and router into that. It didn't work so I pulled it off the wall and found only 2 wires were connected, black and red. White and green weren't connected. It looks a bit like this; So where do I put the white and green wires? I've read the sticky on cabling but I don't really want to call in someone to push 2 wires into a self crimping connecter. Thanks!
