AT&T User Guide
	Unknown callers must identify themselves before they can ring through to your phone. When you answer, you'll hear the name of the caller followed by several options for disposing of the call. Press 1 to accept the call. Press 2 to decline the call. Press 3 to refuse a sales call. If you press 2 or 3, the caller will hear a brief message from Privacy Manager and the call will be disconnected.
