All perfectly correct of course, but we are not using the microfilter for its intended purpose, we are using it as a work-around.
All microfilters for the UK market should have a capacitor between pin 5 of the line, and pin 3 of the phone socket. In other words the filter acts as a master socket allowing our vintage phones to ring.
