In this instance our engineer would help you set up the phones so they all work via the hub.
Please, visit this link and read under Fibre phone compatibility and connectivity - you will find the answer to all your questions related to this matter.
I have copied and pasted the relevant bits regarding your query here:
I have several phones connected to extensions – will these work?
Yes – when our technician pops around to install the new Hub (if you need one) they’ll make sure all your phones work too.
What if the Hub and my phone are in different rooms?
Ideally, the Hub and your phone should be within 2 metres of each other. Our technician will chat to you about this when they connect the Hub. If you’d like your phone to be further away from the Hub, our technician may need to do additional wiring. Don’t worry, this won’t cost any extra.
I hope this helps answer your question.
Can you please, also advise us if you have a scheduled appointment for the installation of the line or not yet?
Let us know and we are happy to help if you need anything more.
