Oh, ny latest pet peeve is these d*mn recorded solicitations that leave their long spiel on your voice mail. Problenm with mine is I can't erase a call until the entire message is played. It really hacks me off!
It was grounds for me getting 2 things: 1. A caller ID box that can recognize certain numbers and play them a discouraging message, and 2. An answering machine without a tape so I can immediately delete unwanted stuff. When playing back -- it shows who called with the message -- delete can come really quick.
