I mentioned the telephone because I had sky a long time ago but the service failed presumedly because of line of sight problems.
However when sky agreed to install their dish on a mast I went back to them because of continuing problems with VM's service.
During the installation the installer discovered that the sky phone line extension that was still there from the old installation did not work. He checked the plugs at each end were connected OK and concluded there was a break somewhere under the insulation. He said he doubted that it had ever worked?
The crew that did that original install were a bunch of cowboys, who got vertigo from standing on a door step, so I'm not surprised.
