Landline Phone Features

How can I change the display screen on my phone? I can't read the screen. It is like gray screen with gray letters.

What happened to the Call Logs that I use to receive in my Monthly Billing Statement?? I need and want them back in my Billing Statement as they use to be.  I pay enough for the phone service I have, which goes up all the time and I get adds on my monthly statement instead of my Call Logs.&nbs

My landline is out of order. How do I call forward to my mobile phone?

Hi!My wifi home phone,(digital phone?) gets about 30 "unavailable", "suspected spam", "telemarketer" and calls from hijacked numbers. I am on the state and federal do not call lists. I have the call screening service thru ATT. And I have blocked a lot of numbers manually. Still, I get about 30 calls
