Suppose for BT it also means any service upgrades to full broadband+voice don’t require another box.

Also as SOTAP is supposed to be “transitional” anyway. Not much point rolling out a a new/dedicated box for that.

You've answered your own question I think. Landline phone is now an add-on for broadband rather than broadband being a service delivered over the existing landline phone. Developing a device with just a telephone socket and a DECT base in it would be a waste of money, and doing things this way allows landline-only customers to 'upgrade' to broadband without any hardware needing to be changed.

Openreach do not provide dial tone services to FTTP customers or FTTC users in WLR withdrawal areas.

If you order just a phone line from BT you will get a low bandwidth NGA service provisioned with a Smart Hub 2.

Yes.
Where we had left BT for providing our broadband, so they gave us a 36-37Mbit (down) and 10-20Mbit (up) for our Digital Voice and sent us the Smart Hub 2 + 4 Digital Voice Adapters.

I thought that there was an adapter just for digital voice, but it turns out it still needs the BT hub thing.

Yeah, I was hoping that I could just use those, and have one of them connected wirelessly to my own router but took a closer look at them and sadly it still requires the Smart Hub 2 to work.

Wow. Could hardly call that a "low bandwidth" service, just to make calls on. That's m ore than a lot of people have for their sole broadband connection 😎😂

Thats what I said to BT when I was on the phone to them when they messed up our switch over to Digital Voice.
They basically told me it's the lowest tier package they provide over Full Fibre, see I would have created a package for voice only or capped it at a lower speed, funny thing is we are not paying for any broadband and our overall price is lower.

I am guessing this speed may reduce once they switch us over to Digital Voice, due to BT contacted us stating we were to be moved over to Digital Voice on a set day, even got a call from them to arrange for a new Smart Hub 2 etc to be sent to us free of charge along with a start date.

Sadly, that start date came and went and only had the broadband activated (again broadband for phone only), so phoned BT and was told that our line is not ready for it yet and that none of this should have happened yet, so now we have broadband at those speeds just sitting there doing nothing and had to plug our phone cable back into the ONT and just wait.

One good thing from this is we are paying less for our phone service, so win, win.

Gosh they really aren't terribly joined up or organised when it comes to this changeover.

Only 8 million more lines to go BT...good grief 🙈

Oh, for sure, they also raised a complaint too, because I had pulled up the original phone cable from the ONT to the Mater Socket, I had to install and tack down new cable, then crimp on a new 431A connector to one end, for it to all then have to disconnect it all and temporary fall back to original cable and tack it back down so it is safe and then plug it back into the ONT.

Now just think if I had accepted BT's offer to send out an engineer to swap over and rewire that cable, to then have to swap it all back.

Don't get me wrong, I am not moaning, hell we are paying a lot less than we were just for the phone line, not that we will be using that broadband speed that they have given us.

On the flip side, I was moved to Digital Voice in September 2019 and it was very smooth, though I was already a BT Broadband customer.

Yep the 8 million was PSTN/voice circuits only. No broadband.

Although this figure from memory one of the recent BT Group quarterly reports (Openreach facts and figures section). But it was something of that ilk roughly.
