It looks like caller ID wasn't active on the back end systems. I've just done that for you now, and it should start working within the next few hours. I've also raised a task  internally to fix the home phone control panel for you.
I've also removed voicemail from the line [this should take a few hours too] as per your thread over here
I hope this helps.
From 31st October 2022, I no longer have a regular presence here as I’ve moved on to a new role.
