BT Digital Voice extension no longer makes phone ring ??

I hate OR.

When I first moved in, they fitted a multiplexer on my wall and said I'd have to add a power socket for it - in my freshly decorated hall. It took years to get them to get rid of that multiplexer, which was slowing my dial-up internet and costing me extra due to the time I was online.

On a visit for a fault (the problem turned out to be in their multi-core supplying the telegraph pole), they complimented me on my extension wiring and it all being in the correct colours. Fault corrected by shifting us to another pair.

The next time they shifted us to another pair again, as we had crackly sound and no internet at all, but only after arguing with them, as they insisted that the sound was okay and that internet was another team - after waiting 3 weeks, with no internet, for them to turn up at all!

On the last visit (turned out to be a module in the exchange this time), by a different person. He disconnected my extension wiring and my high quality ADSL/VDSL filter faceplate, put a link from the master to the nearby secondary, put their own filter plate on there and linked the filtered signals back to an unfiltered plate on the master, as mine was "wired wrong."

I came home just as he finished this, showed him the manufacturer's datasheet and that it had been wired 100% correctly, only for him to decide that the fault was elsewhere and refuse to reinstate my perfectly correct wiring and faceplate.

When we ‘converted’ I opted for a DV adaptor.

I disconnected to existing cabling - which runs to several rooms in the house- from the Master Socket.

I used a short cable with BT male plugs a both ends and a male to double BT socket.

Plug the latter into an extension socket within range of the hub and the DV adapter nearby. Go through the linking procedure and link two with the cable.

You can use the other socket for a wired phone.

The other sockets should also be ‘live’.

We had 3 working initially - a basic desk phone my wife like, a DEC phone base ( which has several handsets but I’m counting as 1), plus an Amazon unit which worked unit Amazon stopped the service ( nothing to do with BT).

I don’t use the phone socket on the hub - there isn’t a phone socket near it.

There is supposed to be a special front plate for the OR NTE5C master socket with a green phone socket (with all 6 wires connected) which is isolated from the incoming copper pair, but that is not what I have got.

I'll see how I get on with the DV ATA adapter first.

Maybe but, in our case, the wires to the extensions were connected to a front plate. I just disconnected them. That left the cables between the extension sockets isolated. We never used the master phone socket.

My EE-branded DV adapter arrived today. It paired ok but has to located well away from Hub+-Router+-TV because the phone buzzes on top of the dial tone.

However it simply does not ring the bloody wired landline on its own. Eventually after looking through threads on the BT/EE community someone with the same issue added a microfilter, so I plugged a microfilter into the DVA and now the phone rings. Unfortunately caller ID just shows "Invalid" and option 1 of 17070 loses the initial word "this".

There was a suggestion that the microfilter reasserts the ring wire but I have disconnected that from my extension wiring. I tried plugging the microfilter into the green socket and my OR (2-wire?) flying extension wiring into the microfilter and the upstairs socket still does not make the phone ring, even though the caller-id shows the incoming number.

This is baffling, it definately used to work.

Back to square 1. My caller-id 30 box with the BT relate 80 dumb phone is back to being plugged directly into the green hub socket and I have the other BT Relate 100 upstairs connected to the EE DVA and microfilter but no caller-ID.

Odd, I just plugged mine in as I described and it worked.

Before Amazon ended the facility ( I had one of their Echo / Alexa variants which linked to your phone) it even announced who was calling.

Sorry, I can’t help further.

I remember when GPO Telophone engineers, were engineers..

My cousin joined the GPO as an apprentice in the early 1970's and went through their in-depth training, which included mains wiring. He spent the first 3 years fixing meters in Leatherhead exchange then progressed to installing and fixing phones, extensions, bells, faxes, etc (all GPO property remember) on customers premises, and then onto business video-conferencing and private leased lines.

He actually did my internal extension wiring which the OR droid simply snipped off (because he couldn't understand it) and discarded even though it was perfect.
