There are but not easy to find. Mum is with SSE and we wanted a call protect type thing which they couldn't provide. In the end it was easier to stick with SSE and buy a Trucall Protect Device which is working well and I can control the scam calls - they get added to a zap list so don't get through. Dozens it's unbelievable! Anyway with sky you had to have broadband but not use it and both BT and sky Mum would have had to press 1 to accept calls and she is blind and can't do any technology. People don't believe you when you tell them someone has no email, no mobile etc!
