Importantly here you are getting upset because a budget low-cost provider with a reputation for not having great service (TalkTalk) are not being helpful. There is clearly not a fundamental problem because the likes of BT are managing to provide lots of information and have a fully developed product offering and have been operating a test facility for the past five years (https://www.bt.com/help/user-guides/phones/digital-voice/digital-voice-adapter, https://www.bt.com/about/special-services/latest-new...

Other providers like Andrews and Arnold with a reputation for catering to the more technical user have published instruction about how to perform voice reinjection - https://support.aa.net.uk/VoIP_How_to:_Voice_reinjec...

TalkTalk are living up to their reputation and price, this is presumably a choice you made when assessing your different options for which ISP to use.

I can see the point you are making but the OP does also need to take some responsibility, its not all TalkTalk's fault.

It’s an SD1 speech dialler

You are stating the obvious. If we all followed “pay your monies take your choices” theory nothing would improve, you are stating the obvious pay and get anything done, your comparisons could apply to anything, cheap flights,cheap health care, where does it stop, this is a service if they don’t deliver they will go out of business , therefore company’s have to listen to their customers or they walk.

Well walk then. TalkTalk can't give you any clear guidance on the impact of their digital voice migration, vote with your feet. TalkTalk have probably correctly determined that catering to people with analogue line requirements over and above a port where a DECT base can plug into is not worth the costs they would incur from having to support them.

What outcome are you hoping for? There isn't a service that ISPs offer where someone comes into your house and re-wires your internal extensions to plug into your router, though the A&A instructions from earlier cover that. There also isn't an option to stay on copper forever (as stated earlier, TalkTalk are going to want to save themselves the costs associated with your analogue line as soon as they are able to), but you have a choice of all remaining options for how you want to handle this.

Lets do one step at a time, the OP is going to check compatibility of their speech dialler with a neighbour's TalkTalk digital voice service first, the wiring is the easy bit with the A&A instructions if the speech dialler is compatible.

Hi just to update, I went round to my neighbours and plugged in a phone into his existing copper fed master socket. This has no connections to the new digital installation. There is No dial tone when the receiver is lifted however when I called his landline the phone rang and so did his phone which is connected to the internet router. So the old copper line is active in some respects. What that means I don’t know.

The old copper line won't be active in any way.

Your neighbour is using an ISP that supports internet calls (Voice over IP or VoIP for short) where the phone is connected to the router and calls are made/received via the fibre connection instead of the copper line.

Definitely rang both phones. I took round a corded handset and the neighbours own rang as well.

Since it's TalkTalk doing MPF then it's possible they have their kit configured in this way to give a lot of overlap before ceasing the copper.

cant walk away yet, got a call from TT customer services today out of the blue wanting to know what the issues are. They will contact me with an answer to my queries as soon as they have completed their inquiries. By the way a lot of presumptions in your post which from a business point of view would render TT useless and therefore out of business.
