So after that I bought a 'ADSL Faceplate Splitter for NTE5' so I wouldn't need a micro-filter but just had an identical issue, and removing it and going back to the master socket with the old micro filter sorted it out.
What could be the issue, any suggested solutions? Is it a bad idea to just keep the micro filter in the master socket / why do we need a face plate? Thanks!
