Message telling me that Landline is blocked

[RuthK2]

We transferred to Sky Fibre broadband a few months ago and we have never been able to use our internet landline number since then. The message we get is the number is blocked

@RuthK2 where are you getting this message? I've not heard of it before. I assume you have full fibre broadband, with a separate fibre optic cable to your home? Is your phone handset plugged into your Sky broadband Hub?

[RuthK2]

When anyone calls our landline, a  voice message is given that the number is blocked 

[RuthK2]

Yes, we have full fibre broadband and the phone is plugged into the hub

@RuthK2 dial 17070 and listen to the recorded message. It will tell you what your landline number is. Is it what you're expecting it to be?
