BT Digital Voice and Full Fibre? Several questions please.

First some background. I understand that we will all be compelled to switch to BT Digital Voice by 2025 as the old analogue phone system is shut down.
This house is currently on BT VDSL FTTC 24Mbps down and 6Mbps up and standard BT phone line. It is currently being offered BT Full Fibre - this is 01803 (Torquay area).

I'll try to break my questions down into chunks as they cover rather a lot, and I'll number them. I've done my best to research online. I am also very familiar at another location with Gigaclear fibre and with use of Vonage for phone calls (including how to safely wire the Vonage box to existing home phone extension wiring so all old wired and cordless phones work as before).

Phone calls
(1)The current hub is BT Hub6. I have looked at the BT Digital Voice Adapter. Would I need a new hub to use the BT voice approach and would that hub work with VDSL like the current one?

The house is long with thick stone walls that wireless signals do not pass through. The hub is in an underground comms room. The house is wired with CAT6 thoughout for voice and data and there are three wired phones and one cordless phone system.
So I would need four of the BT Digital Voice Adapters. It seems a messy solution. I also see reviews saying sound quality is poor.

(2) Looking at the BT website it appears one can now use BT broadband without paying for a phone line. So I'm thinking I could order a Vonage box, plug it into the existing BT hub, get the current BT phone number transferred to Vonage, then terninate the BT phone service. That should avoid the 2025 issue. It would allow me at no cost to keep all the existing phones and wiring as now. Do you see any problems with this idea?

Broadband
(3) Can I stay with FTTC or will I be compelled at some point to go full fibre?

Much as I would like full fibre the present service is good enough and I'm worried about installation.
There are practical problems with installing fibre as the line goes on poles through a wood (do they put fibre up on the poles?) and then down a pole at the garden border into the ground, then through a conduit in the garden under a tarmac path and then somehow through a thick wall into a comms room that is effectively underground. (This used BT Openreach recommended components when built 10 years ago). I have calculated that a long drill aimed up at an angle near the ceiling should come out an easy digging depth outside. But it all looks difficult and non-standard.
(4) What would BT Openreach do when confronted with this challenge?

You don’t have to use the BT Digital voice at all, choose your own VOIP provider, use whatever kit you’d prefer.

FTTC will be around for a fair while yet.

If you transfer out your existing number now it will also terminate your FTTC service so this is not recommended.

Thank you, I would not have guessed that.
The BT website says that if you terminate the phone service you lose the number and cannot get it back.
But if I try to transfer the number it will terminate the whole BT service including the broadband.

So it seems to be a Catch-22, and there is no way to switch to a VOIP provider such as Vonage and keep the BT broadband without losing the number? This seems crazy.

There is a way.

Order a new FTTP broadband only service, ( be very careful not to Transfer your voice service or cease your fttc service). When FTTP is working transfer your number to the VOIP provider of your choice. This will cease your FTTC service.

That is ingenious, thanks for the suggestion. That would be an excellent solution for most people.
Unfortunately,as you see from my questions, it seems likely getting FTTP could be very difficult in this house.
It would be helpful to know if Openreach when installing FTTP are willing to tackle special cases like mine, perhaps making an estimate for an extra charge or subcontracting it to a specialist installer?

It really is the ONLY way to ensure that a cherished landline number is not lost. It has another advantage too that if the FTTP installation runs into problems with the installation, then you still have a working broadband and voice service. The downside is that for a while you are paying for two services. It is also possible that you might be charge a termination fee on your former service and might have to continue with the service for longer than you wished to.

Don't forget to factor in a porting charge by the gaining VoIP provider of the number. Whereas if you took out a new number with the VoIP provider there is no fee payable apart from an ongoing monthly fee which most hosted VoIP providers charge.

Could also order a second FTTC service to be installed. Once that is up and running migrate the number from the original service and that will cease it. As long as there is a spare pair it should be possible to get a second FTTC in the premises. Downsides are again that you would have a crossover of paying for 2 services and also the second pair might be lower quality than the first so could have poorer Internet performance.

The hubs have a phone port on the back I think, so you could use this to wire in all your existing telephone extensions. If you need better wifi coverage you could use your cat6 wiring to add additional access points
