I disconnected some of the wires going to and from my router when cleaning

I was making sure each time I disconnected one that the internet still worked, not thinking it may disrupt the landline. Now, the landline is not working. 

Not sure if linking to images is allowed, but this is the setup. I dont think anyone who sees these pics will be able to tell me how to fix it, but maybe its worth a shot. Any advice is appreciated.
