Hi folks, need some help please. This afternoon our phone line decided to stop working. We unplugged the phone at the master socket and tried another phone in the same socket, still not working. Called BT on the automated fault diagnosis number (from the mobile) and twice they tried to test the line but were unable to do so. Eventually we spoke to a human at BT who was able to test the line and who suggested the fault was in the property. We also used the test socket behind the face plate to test the line, again nothing. The really strange thing is that our broadband access is still working, which would suggest that the line is ok both inside and outside. Engineer is coming sometime Thursday morning so would like to be forearmed and ready with some info as the call-out and repair costs are extortionate if the fault is on 'our side'. Any help would be greatly appreciated. Thanks in advance.
