Eldon Boy and OMAs previously mentioned I also use a BT8500 (powered by truecall) and have not heard a scam call for years. The only thing I cannot do with it is see a list of all the numbers I've blocked.
Thanks for that, I bought a standard phone, instigated call blocker but as I said it seemed to block all calls. I will now look anew. Eldon Boy that is the clever thing to do to keep you number live, had the same problem as you, took it back to EE who reconnected FOR and suggested one quick call a month to keep it live and the one to your home phone when you are stood by it is the one they do not want.
