Hello. I'm having the exact same problem setting this up for my Mum. She has BT basic but customer services are saying she can't have caller display on the line, how can I get through to the BT basic team to basically read this reply to her which seems to solve the issue. Thanks in advance.
Thank you for posting and welcome to the Community. I've moved your post onto your own thread as the other one had been marked as solved.
I'm sorry if your Mum hasn't been able to get Caller Display. If you send me the details, I'll be able to help you get that set up.
