You may have just saved me some experimenting - that is my plan for here.

Can't you plug the ONT into WAN 1 on the USG - configure the PPPOE as the primary connection.

Plug the EE dongle into the HH and set its IP to be a different subnet (e.g. 192.168.10.2) and then plug that into WAN 2 of the USG and configure as failover in the controller.

The HH is permanently connected to the EE dongle but is only in use if needed if your FTTP goes down.

I have done this on my line (admittedly g.fast not FTTP and using udm pro) and it works without any issues. I have seen that there is something to do with fault logging if the EE dongle is in use but as no traffic is passing over it then not sure if that would count and have not had anything from BT in the last 4 months since I set up this configuration.

If I understand correctly, the Home Hub is permanently disconnected (because it is powered up but not connected to the ONT) and permanently failed over to the EE dongle. But no traffic is directed to the Home Hub as it is WAN2 and only triggered on failover. Makes sense. and yes I can see that it might keep reporting to BT that it has failed, and presumably sends keep alive/status/connection traffic only.

That could work. Never played with failover the USG-Pro but have another site I manage with 4 connections load balanced on a Draytek (ADSL, GSM, WISP & Starlink) so should be straight forward-is.

I am on a 300/50 at £51.95/month! So a reasonable price for 900/110

I did find an "issue" with the BT Business Hub in that it restricted the upstream to around 33-35 Mbps, whereas a Residential Hub or direct PPPoE gave just under 50. There is the possibility the bug/issue may still be there and restrict the 110 to a lower level.

I have three other VoIP numbers which are routed through my Gigaset base and those are used most of te time. The single BT one is there and rarely used - some people still use teh number or for outgoing 0800 calls.

I saw some of the upstream issues last year limiting throughput. I have kinda assumed it must be sortable as I haven't seen much of it lately. Last year they were all home working etc and getting used to things so possibly not able to troubleshoot glitches like that well in the beginning. They have promised me 100 so they better deliver!

Need to get my head around the reliability and benefit of VOIP as previous experiences have been patchy at both previous employers and my one dabble at home. In theory it sounds great having the home phone ring on an App. We have a big site with good WiFi coverage, we currently divert to mobile after 4 ring-rings but need 5 handsets in the house to grab the phone before it diverts. Having it work anywhere across site would be awesome. But having it not work as its patchy is worse than divert.

It was quite simple in the end and works really well. You only get a slight blip in connection when it swaps over from one to the other and is hardly noticeable unless you are gaming!!

Forgot to add, disable wireless on the HH, and turn off DHCP..

I can dig out all of the settings on both udm pro and HH if needed.

Yep, that's how it is showing if you log into the HH - FTTP not connected, 4G Assure - connected.

UDM pro shows

WAN1 - My BT IP address
WAN2 - 192.168.10.2 - a static ip relating to the HH address range.

The only thing I have no idea about is the voip side of things as not using that. Does it go via the HH via a dedicated port or can it run through any ethernet port on a network?

The BT Hub - no problems for me. The UDM-Pro, they woukld be useful, when you have time, so if you can put them in a Message to me that would be great.

Getting the TBB BQM to work was a little challange with UDM-Pro settings but now have both v4 and v6 monitored.

The OP is using BT business, so a slightly different hub, and teh phone bas just needs an Ethenet port.

That ought to work beautifully for pure broadband but, without using the 4G modem I can’t see how the BT voice service would work. No biggie I suppose if the OP uses another regular VoIP provider.

OP has ordered BT *business* where the voice service is handled by a separate VOIP phone, not by the ATA on the hub.

Good point. I was definitely thinking of the domestic hub. As such it should all work via the Ubiquiti.
