3. Telephones - pros and cons
Advantages   | 
        Disadvantages  | 
      
|---|---|
You get immediate feedback to things you say  | 
        The person must be available to take your telephone call  | 
      
The conversation is relatively private between you and the caller - although others might be able to hear what you are saying.  | 
        The line might be engaged when you call so you can't speak to the person when you want.  | 
      
You can call someone anywhere on the planet  | 
        You generally have to pay for every minute you spend on the call. In the case of mobile or overseas calls, that can be expensive.  | 
      
Calls can be made 24 hours a day, 7 days a week  | 
        There might be noise or interference so the quality of the call could be poor.  | 
      
Internet based calls can be free  | 
        With mobile calls you might move out of the range of a transmitter and so the call gets cut off.  | 
      
Internal calls within a business are usually free of charge  | 
        You cannot see each other's body language so a lot of the non verbal communication is lost  | 
      
Most people have a telephone. No specialist equipment is needed.  | 
        It is not easy to make a record of what is said during the call. Things might be forgotten or mis-interpreted.  | 
      
If there is an answerphone, you can leave a message if the person isn't available to take your call.  | 
        With standard telephones, only spoken information can be exchanged - you can't send files. Smartphones however do have this facility.  | 
      
If you don't know the telephone number you need there are plenty of services which will help you get the number (although they can be quite expensive).  |
