You talked into the mouthpiece and then held it to your ear to listen. For a century of so, using the telephone meant either contacting the operator to dial a number, or dialing yourself. After that, all you had to do was talk or listen. Nowadays, the telephone has become a very complex instrument; it rivals the computer as to the number of possible uses. Answering machines have been around for several decades,but they are now being replaced by voicemail. Voicemail does away with the need for an answering machine. Messages are stored on the system. That means that it is possible to forward the message to someone else's phone, or transfer the call to a more convenient phone of your own. You can also use "call pickup," so that anyone in your group can answer another's phone. Conference calls have become very common. This is when one person phones first one person, then another,and keeps adding people to the telephone conversation. This can regularly be done with up to six people. It is very useful for business discussions where different people need to talk about the same thing. It also speeds up the process of consensus, and allows everybody to be in on the decision or discussion. The modern phone has many more features. If you don't want the caller to know what is being said in your office, you can push the "mute" button. If you want to hang up without putting the receiver down, press "goodbye. If you don't want to receive calls, just forward them all into your voicemail. Newer phones will indicate when you have voicemail messages. If you have trouble with these features, an automatic voice will tell you your options. This help-system is built into the telephone. For example, the help-voice will tell you how to set up a distribution list,so that you can send the same voice message to a number of people. It will also tell you how to send a message directly onto someone's voicemail. You can designate your message to go to the top of the recipient's voicemail list. You can also program it so that the recipient cannot forward it. Some systems have limits on how much space can be used for individual voicemail. There are a number of courtesies that voicemail users should follow. Your greeting on your voicemail should be simple. If you are unable to take calls for any reason, you might want to explain that in your recorded greeting. If you are on vacation, you might want to include that information in your greeting. Don't use voicemail as a way to avoid answering the telephone. Some people use voicemail to screen calls; this can be annoying to someone who can never contact you directly. Check your messages regularly and reply to them promptly. Enjoy the telecommunications revolution! 翻译 电话系统 当亚历山大·格雷厄姆·贝尔（AlexanderGrahamBell）在19世纪70年代开发电话时，它的使用相当简单。你对着话筒说话，然后把它放在耳朵上听。一个世纪以来，使用电话意味着要么联系接线员拨一个号码，要么自己拨号。在那之后，你所要做的就是说话或倾听。如今，电话已成为一种非常复杂的工具；在可能的使用功能数量上，它可以与计算机匹敌。电话答录机已经存在了几十年，但现在正被语音信箱所取代。语音信箱不再需要答录机。消息存储在系统上。这意味着可以将信息转发到其他人的手机，或将通话转接到自己更方便的手机。你也可以使用“呼叫接听”，这样你的团队中的任何人都可以接听其他人的电话。电话会议已变得非常普遍。这是指一个人先给一个人打电话，
