Getting a phone working in my workshop I used a old Mk 1 NT5E face plate (my old master socket which OR chap left me) to get the phone to ring without a 'dangly filter' .
A normal DSL micro filter, dangly or otherwise, serves several purposes...
1) it prevents the attached apparatus from passing interference back into the DSL.
2) It prevents the DSL signal from causing audible artefacts on phone.
3) It generates a 'ring' signal for attached telephones.
A traditional 'master socket', ie NTE 5, will function as per (3) in generating the ring signal, and will make old fashioned phones ring. But it won't provide any filtering per (1) or (2) hence won't stop the attached telephones from impacting DSL. It may also allow bleeps and whistles to be audible.
If the affected segment of phone wiring is already filtered from DSL of course, that would be a different matter. Apols, as always, if I have misunderstood.
