Hi @suemog
Thanks for posting and welcome to the community.
My apologies for the landline issue. I've ran some checks on our system today. You need a technician visit anyway, as some of your broadband downstream power levels are out of specification. I've booked the tech for that and put on the comments section about the landline as well 🙂
You can find details of the technician visit here
Please let us know how the visit goes
Kind regards,
