My landline is my primary phone line. Nobody there would be the biggest caller.....rings....and nobody on the line or dial tone when I answer, followed by Doctors and Robocalls.
My cell phone, my brother is about the only one who even calls me on that phone. I don't give out that number so only family has that number and for some reason he has decided to call that number instead of the landline. Cell phone is really just for emergency calls when I am away from the house and the landline.
