The ADSL filter's 431A plug or connector, is stuck in the bt wall phone socket thing in the upstairs landing and I can't get it out. I am having Sky fibre switched on tomorrow and need to replace the old ADSL filter with the new sky filter for fibreoptic broadband. Any idea guys how I can get the thing out, as its doing my head in. I can't yank it out, I don't want to damage anything in the wall phone socket.
