To answer other questions posed, the master socket in the hallway is just the usual master socket with a split lower half which if taken off [as allowed] reveals no extension wiring attached.

Which doesn't make sense. Where is the "new" master getting it's feed from? You said in a previous post that the new wiring to the "new" master is internal. Can you not trace it back to where it is picking it's feed from?

Yep actually saw the cable run being made which is white circular cabling off the roll from his van which starts it's journey from the old standard master socket to the new filtered master socket. As I said previously, I though he was just extending the exchange wires behind a decommissioned master socket, left behind because of a lack of blanking plate. It is only recently that I discovered there continued to be a voice service from this socket.

Zen have said today that if I connected a corded phone to the [new] master socket and a ghost call happens overnight in the next three nights, then they will organise on Monday for an Openreach engineer to visit.

The word "previous" in the first quote would have saved a lot of time........(Your new socket is an extension from the old socket)

If 1471 does not record an incoming call, it aint an incoming call.

I would ask zen to run a copper line test and see if that triggers the rings. It may be that the overnight line testing routines are causing the problem. Some cordless phones don't like it.

If that don't work check insulation between terminal 2 and 3 on internal wiring as this will cause spontanious ringing.

If that don't work I would be looking to eliminate plugged in kit.

Currently (?) no extensions from the faceplate on the master socket in the hall suggests that Kelly's connected the white extension cable to the back of the master directly to the drop wires but the test socket in that master is still live, hence a phone still works from it's unfiltered faceplate!

If that is the case then you definitely need Openreach to sort it out.

Is there a pair from the back of the new NTE5A faceplate backwired to the old NTE5, with the incoming cable from outside being connected to the new extension cable instead of the back of the NTE5 rear assembly? Then the same-coloured two wires as on the new NTE5A connected to the back of the old rear assembly?

That would be filtered voice only available from the old NTE5, in the hall, via that backwiring arrangement?

How is backwiring going to cause spontaneous ringing?

Kellys could have sent their worst cowboy around but he ain't going to have messed up an install to cause the symptoms the OP is describing.

This will be the line tester routines or plugged in kit or plugged in kit not liking the line tester routines.

Yes. As one would expect from all engineer installations of FTTC.

There is scope for a cockup in the Kelly's installation, and cockups by them are what we often see.

I described a valid backwiring installation, asking if that is what has been done .

If that isn't what he has done, giving rise to an unfiltered phone feed somewhere, we could get the effect reported.

I must admit that I hadn't considered the possibility of backwiring and from your description I can see how filtered voice would be available at the old NTE5

However I think the OP stated that there are no extensions from the filtered faceplate on the new NTE5 in the living room...
