Ask VM (via the VM forum team on here, when they reply to this topic) to modify your home phone wiring so you can use your existing landline extension sockets via the phone connection from the VM hub.
VM should offer to do this free of charge for you as part of the switchover process.
Make sure they make modifications to your phone wiring so you can keep each piece of equipment in the same place (rather than the offer which sometimes crops up on here to move the hub to a different location).
Modifying the phone wiring may require some changes to internal cables in the home. How much work is involved will depend on existing locations of equipment and cable routes alongside any aesthetic considerations.

Do I need to book a technician visit? You’ll need to book a free technician visit if...
• You rely on your landline for accessibility needs or don’t have a mobile to make an emergency call – we’ll provide you with an Emergency Back Up Line so you’re always able to call emergency services.
• You’ve got connected devices such as a burglar alarm linked to a control centre, use a telecare device, or have other phones connected to extension sockets. You’ll need to contact your provider and let them know about the switch if you have any of these to make sure they’re compatible with a fibre service.
• The Hub and your home phone can’t be placed near each other.
Alternatively, a cordless phone system allows you to use phones around the home with no wiring modifications or disruption. Plug the cordless base station into the VM hub and use the cordless satellite phones around your home as required. If you already have a cordless system, you may be able to add in another cordless satellite phone to the existing setup as/if required. If you needed to buy a cordless phone system, to avoid any rewiring work, this would be at a cost to you.
Your external bell should continue to function (if VM modifies your phone wiring) but the phone connection from the hub has a REN of 3 (typically 3 devices connected) and may not be able to drive all devices connected. A mechanical bell may require an additional wire for a ringer connection and may need a different adapter to the hub. Alternatively, you might be able to find a modern electronic sounder device to replace the bell.
You will probably only find out what works once you try to connect it all post switchover.
