The previous owner of our house fashioned his own extension line from our main square white BT phone socket box thing (I've tried to upload a picture showing what I mean, the black line is the improvised extension).
I want to disconnect this extension as it runs up through the corner of our living room ceiling in an unsightly bodged manner, to a phone point upstairs which we never use.
Phone lines have electricity, don't they? Am I going to electrocute myself if I do it? I don't think turning off the consumer unit trip switch is going to be any use 'cos the current comes through the actual line, I always thought.
Any ideas which don't involve getting a spark in (costs too much round here, but of course I will do if I'm going to kill myself) :)
