Hi JC-RW,
Welcome to the Community Forums, thanks for your first post.
I have been able to locate your account and it doesn't look like you're set up for VOIP landline services yet, meaning that you will still need to plug in your landline handset into your wall socket for it to function. We're aiming to migrate all of our customers over to voice over fibre by 2025. You can find more information about this here
If you have any other questions, please don't hesitate to ask us.
