Avoiding a phone in a cupboard

Hi all,
Apologies, complete tech newb here so please be patient with the questions!

We recently migrated from BT (with a standard landline) to hyperoptic, which (because i didn't read the fine print) I didn't realise comes with VoIP. The hyperoptic box is shut in a cupboard in a utility room so the only way to have a functioning landline at the moment is to plug the old phone directly into the router and have it sat just outside the (not particularly accessible) cupboard.

Now...on the old BT system the phone was connected by a standard phone cable (RJ11 I think) to the phone jack in the wall by the front door. This jack port also has an ethernet connection point which wasn't hooked up to anything. In the cupboard the old FTTP box had a phone port and this was wired to a phone jack in the cupboard using something like an RJ11 but with a flatter fitting at one end. This, presumably, then distributed the phone signal throughout the house.

My question is, without using a ton of ugly wiring just running through two rooms and several doorways, is is there a way of running the new VoIP cable from the router to the phone jack/ethernet port in the hall.

Any thoughts and help much appreciated!

Yes - with caveats. What you are attempting to do is called “voice re-injection”. Catchy huh 🤣

Basically you are using the existing voice extension cabling (and outlets) and repurposing them slightly to use the router voice port in lieu of the ‘landline’ in the master socket. The most important thing to do is to fully isolate/remove the incoming external copper line from your master socket.

For some background reading, see the wiki on the A&A support site:

It's not totally clear from your post, but did you have FTTP with BT before, and your telephone service came from the Openreach ONT and was connected into a socket in the cupboard? If so, you can remove this cable from the ONT and plug it into the Hyperoptic telephone port instead and all your sockets will come alive again.

Is the Hyperoptic connection in the same cupboard as the Openreach ONT? Can you take photos and post them to make things clearer?

Edit: Here is an Openreach FTTP-only install that I found on Google. The telephone socket underneath the ONT is the outgoing line from the ONT serving the other telephone sockets in the house. If that's how yours looks then you can plug the Hyperoptic router into this socket.

It’s not 100% clear but it does sounds like the OP was possibly using the old Fibre Voice Access (FVA) product from the Openreach ONT - as per your stock photo - and this was already being re-injected into the extension wiring.

However the “old FTTP box” may have also been a BT SmartHub and using BT Digital Voice. Not that should really matter to the end result, but what the OP had may not match up with your stock photo.

In any event it sounds hopefully like a plug and play solution - but I’d still urge caution for the OP and anyone else reading to make sure that there is no external copper PSTN line connected into the master socket / extension wiring before reinjecting voice into there.

hi all, many thanks for the insights, just took a load of pictures and annotated but there seems to be no obvious way to upload them in the reply...

You need to upload them to a 3rd party image hosting site or something like Google drive and then link them here.

Excellent, thanks!

Hopefully this works. I've included an annotated one, one of the original box where the phone line plugged in in the cupboard and one of the outlet where the phone originally plugged in. As you can see from the mess of wires the phone is currently plugged directly into the router.

You could plug a DECT base station in and leave it in the cupboard. Put handsets wherever you want. No cables.

You didn't put any text in the section after the URL, so it displays as blank. If you can edit the post, just add the word pictures after the ] and before the [/url section.

Photos make it clear. You previously had what is called Fibre Voice Access (FVA) which emanates from the voice port of the Openreach ONT inside the white enclosure. This would have been connected into the telephone extension wiring via the shuttered socket on the wall in the cupboard and connected to the similar shuttered phone socket outside.

You ought to be able to similarly connect the voice port from the Hyperoptic router into the same wall socket and similarly connect your analogue phone on the outside wall socket.
