2--It's simple. You can use call transfer.
 
1--Is it so simple?
 
2--Sure. You know，we spend most of our time at home or in the of-face every day，so I receive handset calls with the hand-free telephone，so I need pay little for receiving calls.
 
1--lt's true.
 
2--Call transfer has many other advantages. When I am in places where network can't cover, such as the high building, I also use call transfer function，which transfers my calls to the hand-free telephone and I will not miss any call.
 
1--That's all?
 
2--In hospitals or on planes，handsets will interfere with some equip-ment，so we must close our handsets. If you set call transfer, the problem will be solved.
