My partner has a business landline at his flat (probably copper, possibly FTTC)
He will eventually be moving in with me, and will need to keep a landline - ideally the same number for ease of continuity.
However, I've got FTTP from TalkTalk which, although amazing, doesn't come with a landline.
What can we do/what's the least hassle to ensure he can smoothly transition to having his business at my address?
We can look to arrange a move to bring that line to your address. Depending on the availability of copper lines in your area, this would either be a new line installed with this number or a cloud-based line.
If you'd like to discuss this further, please send me a PM and I'll take some of your details.
