My cordless phone bit the dust this week. (Yes, I still have a landline--I make way too many local calls to waste peak cell phone minutes on them.) It started emitting a terrible buzz that interfered with the line so badly that calls weren't coming through. It wouldn't let me dial out or hang up, either. I did call the phone company to have them run a few tests just to make sure that definitely was the problem, and as soon as I disconnected it, everything was clear on the princess phone I keep in the bedroom.
So I have to add "shop for new phone" this weekend.
