Hey @Nickster,
Welcome back to the community and thanks for taking the time to post.
I'm sorry to hear of your landline issues, you can plug your landline into your hub but you can only do this once home phone change over has been completed. I have checked on the system and your area is yet to be informed of the change over and I cannot see any updates as to when this is going to happen
If you were to plug the landline into your hub now, it simply wouldn't work.
I have refreshed your number on our network, please can you let me know, if that has made any difference.
Regards,
Steven_L
