Although I would prefer a faceplate filter, I would first have to fit an NTE3 backbox - which I am perfectly capable of doing (and even have both backbox and faceplate) - but I try to be a good boy and not tamper with the master socket wiring! I therefore have the next best thing, with a plug-in filter in the master socket and anything else (i.e. a PABX and one direct 'phone) plugged into that.
