Thanks for your post and welcome to the community.
I'm sorry you're also being affected by this.
As our community have advised, it can take up to 24 hours for the line to be activated. Currently, there is an issue meaning this could take up to 48 hours. If you are still having problems after this time, then please pop back here and I can help.
Sorry to jump on the back of this rather long issue but I too have the same issue.
Recently installed the hub4 router and connected the phone to the router via port 1. Have tried rebooting and I still get the 'telephony disabled' message within the hub page as well as my telephone advising me to 'check the phone line'.
Any chance this could also be looked into? Done the usual telephone wait but gave up after 45 minutes.
I'm currently working from home so any day or time works.
Thanks for arranging this!
One final thing, are you able to determine when the fault occurred? I'm little concerned that I've been paying for a service that simply hasn't been working and wondered what sort of recompense I'm entitled to.
