     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0018]    Referring to FIGS. 1 and 2, the invention mainly includes a conversion device  1  linking to a fixed telephone line T 1 , a fixed line telephone T and a mobile phone P.  
         [0019]    The conversion device  1  consists of:  
         [0020]    a microprocessor  10  which coordinates operations of various units of the conversion device  1  to control interactions between the mobile phone P the fixed telephone line T 1  and the fixed line telephone T;  
         [0021]    a fixed line/mobile phone switch unit  11  linking to the microprocessor  10  to receive control signals of the microprocessor  10  and select the fixed telephone line T 1  or mobile phone lines;  
         [0022]    a DTMF decoding unit  12  linking to the microprocessor  10  to transmit decoded signals to the microprocessor  10  for processing;  
         [0023]    a caller identification voice unit  13  linking to the microprocessor  10  to transform incoming telephone numbers to voice for broadcasting in an audio fashion;  
         [0024]    a fixed line detection unit  14  controlled by the microprocessor  10  to test the incoming phone calls and phone communication on the fixed telephone line T 1 , and through the microprocessor  10  to control the fixed line/mobile phone switch unit  11 ;  
         [0025]    a mobile phone communication interface  15  linking to the microprocessor  10  to transmit and receive signals of the mobile phone P; and  
         [0026]    a voice switch  20  for determining whether to hear the telephone voice of the incoming call before taking the incoming call.  
         [0027]    By means of the construction set forth above, the conversion device  1  connects to the fixed telephone line T 1  and connects to the mobile phone P through the mobile phone communication interface  15  to complete the installation of the invention. Users may use the voice switch  19  on the fixed line/mobile phone switch unit  11  to determine whether to hear the telephone voice of the incoming call before taking the incoming call. When the voice switch is in an ON condition and there is an incoming call from the mobile phone P, an user may take the handset of the fixed line telephone T, and the caller identification voice unit  13  generates the voice of the telephone number of the incoming call that is output on the handset of the fixed line telephone T through the fixed line/mobile phone switch unit  11  (while the telephone is still not yet hooked up). If the user decides to take the incoming call, he/she depresses a preset key (such as FLASH key or receive key) on the fixed line telephone T. If the user does not want to take the incoming call, he/she may hang up the fixed line telephone T. On the contrary, when the voice switch is in an OFF condition and there is an incoming call from the mobile phone P, the user may directly take the handset of the fixed line telephone T to take the incoming call.  
         [0028]    In the event that there is an incoming call from the mobile phone P and the user uses the mobile phone to take the incoming call, in the mean time another incoming call is coming through the fixed line telephone T, an interruption tone may be heard on the mobile phone P. Then the user may decide whether to take the incoming call from the fixed line telephone T. If the user decides to take the call, he/she depresses the “#” key and uses the “#” key to switch between the mobile phone and the fixed telephone line T 1 .  
         [0029]    Refer to FIG. 3 for the structural block diagram of a second embodiment of the invention. In this embodiment a FSK signal generation unit  12 ′ that is able to transform the incoming phone number to a signal recognizable by the fixed line telephone replaces the caller identification voice unit  13  to enable the fixed line telephone to display the incoming phone number.  
         [0030]    Refer to FIG. 4 for the structural block diagram of a third embodiment of the invention. In this embodiment a vibration ring generation unit  17  and a vibration ring and mobile phone switch unit  16  are added to the original conversion device  1 , wherein:  
         [0031]    the vibration ring generation unit  17  generates vibration ring signals to the vibration ring and mobile phone switch unit  16 ; and  
         [0032]    the vibration ring and mobile phone switch unit  16  receives the vibration ring signals from the vibration ring generation unit  17  and is linked to the microprocessor  10  to determine whether to send the vibration ring signals to the fixed line/mobile phone switch unit  11  and to connect the mobile phone communication interface  15 .  
         [0033]    Through operations of the vibration ring generation unit  17  and the vibration ring and mobile phone switch unit  16 , when there is an incoming call from the mobile phone P, the vibration ring and mobile phone switch unit  16  will output vibration signals to trigger the vibration ring generation unit  17  to generate vibration ring signals to the fixed line/mobile phone switch unit  11  to make the fixed line telephone T to generate vibration ring to avoid missing phone call due to too little ringing on the mobile phone P.  
         [0034]    Refer to FIG. 5 for the structural block diagram of a fourth embodiment of the invention. In this embodiment a music generation unit  18  is added to the original conversion device  1 . The music generation unit  18  enables the waiting telephone line to hear the resided music during the fixed line/mobile phone switch unit  11  is making switch. In other words, while the fixed telephone T is busy in use and there is an incoming call from the mobile phone P, an interruption tone will be produced. If the user wants to take the incoming call, he/she depresses the “#” key on the mobile phone P while another line will be held and hear the music output by the music generation unit  18 . If the user wants to resume the conversation on another line, he/she needs only to depress again the transfer “#” key. If the user wants to hang up the fixed line telephone T after having finished the call and take the incoming call from the mobile phone P, he/she may depress the preset key (such as FLASH key) to make switch. Similarly, if the user wants to hang up the mobile phone P after having finished the call and take the incoming call from the fixed line telephone T, he/she may depress the preset key (such as FLASH key) to make switch. The user may also hang up both the fixed line telephone T and the mobile phone P by returning the handset to its home position.
