If your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

But they offer a Digital Voice adaptor. This 'pairs' to the BT router and can be positioned anywhere in the house ie where the handset (or base station) is positioned.
Any information on trying to use it with Netgear router?

Methinks that google1901 will be utterly baffled by this bit of boilerplate. That they have already worked out how to get rid of BT's nasty hardware shows that they are well beyond this stage.
I step in only to warn them that it almost certainly has little, or nothing to do with their request for advice on how to get BT's new Digital Voice phone system to work with a Netgear router.
CrimpOn has gone over some of the issues. But anyone interested in investigating the true nature of BT's crimes against humanity might like to read this:
Digital Voice | Digital Home Phone | BT
The question is about using this technology without being forced to connect via BT's famously horrible hardware. (Way back when it was, literally, a part of the ministry of communications, its predecessor loved inventing unique technology that no one else in the world adopted, a habit that seems to persist.)
We will need to know how the promised DECT adapter will work with third party hardware.
There's a lot of chatter out there about this technology. One post confidently asserts:
The website Broadband News is a well informed source of information. This post talks about the kit that BT supplies, which offer a few clues. But I suspect that google1901 has already been down that road.

Somehow, I can't see Netgear experimenting with BT's new system. Happy to join in of they do want guinea pigs.

My thanks to @FURRYe38 I'll check out the website you mentioned. This is just the start where I'm heading. Regardless of eventual outcome, once digital voice is upon us, I'll not have anything to do with BT smarthub2 router. Thanks for the input.
