HOW TO BLOCK CALLS??
Although it's not documented in the book or the phone, when you get a call and press either part of the upper side key, it will silence the ringer and send the call to voice mail after the usual number of rings. If you press and hold either part of the upper side key, it will silence the ringer and send the call to voicemail immediately, which you might not want to do because the other person could realize (if they're smart) that you did this and are avoiding them.
