I had a message from my mother asking me why when she phoned was I always on another line. It was odd as I hadn't been on my phone. On further investigation it appears that my phone has been blocking her number. It says "blocked call, blocked by phone". I have checked my blocked call list and her number wasn't on it. Out of paranoia I have removed all of the numbers from my blocked call list. Does anyone have any idea how to unblock her number?
