Hi, Our landline phone has stopped working, but our broadband continues to work. I have included some photos to show our set up, any ideas on what might be wrong? We pay for broadband, phone and tv with sky. I'm wondering if the thing that says 11B on it has broken/gone? The cable comes into the house by the window, to a small box with a screw on the top (see 1 of the three pics) and then the cable runs to a bt master socket? (unless that is what the thing by the window is? I'm not sure what these things are all called), anyway, and we don't have a dialling tone, but our internet is working? It's only the two blue cables that run to A and B. Any ideas please?
