     Refer to  FIG.  1   , which schematically shows a system architecture wherein a telephone device is integrated with an electronic conference system according to a first preferred embodiment of the present invention. Below are introduced the devices and units of an electronic conference system and the functions thereof. The operation process thereof will be described thereinafter. In  FIG.  1   , a system  10  comprises a telephone device  11 , a telephone exchanger  12 , a conference server  13 , and a conference terminal device  14 . The telephone device  11  is in signal connection with the telephone exchanger  12 . The telephone exchanger  12  is in signal connection with the conference server  13 . The conference server  13  is connected with the conference terminal device  14  in a wired way or a wireless way. A display device  15 , which does not belong to the system  10 , is connected with the conference terminal device  14  to make the persons in the conference room able to view the images. In the embodiment, the telephone device  11  may be a conventional analog type telephone device, which transmits data to the telephone exchanger  12  in a Dual Tone Multi-Frequency (DTMF) format. The conference terminal device  14  may be a desktop computer or a notebook computer. 
     In one embodiment, the telephone device  11  allows a user to transmit pairing data to the telephone exchanger  12 . The pairing data is used to pair the telephone device  11  with the conference terminal device  14 . The details thereof will be described thereinafter. The telephone device  11  also allows the user to transmit conference instruction strings to the telephone exchanger  12 , wherein the conference instruction strings will be converted into conference instructions for controlling the electronic conference. The details thereof will also be described thereinafter. 
     The telephone exchanger  12  is used to convert the pairing data into a pairing instruction and transmit the pairing instruction to the conference server  13 . In another embodiment, while the telephone exchanger  12  receives the pairing data and verifies that the pairing data include an extension code, the telephone exchanger  12  performs an Interactive Voice Response (IVR) function to instruct the user to operate the telephone device  11  to input the conference terminal recognition data, a user account, and a user password. Then, the telephone exchanger  12  converts the conference terminal recognition data, the user account, and the user password into the pairing instruction and transmits the pairing instruction to the conference server  13 . 
     The conference server  13  has an electronic conference system. The user may use the user account and the user password to log in the electronic conference system to attend an electronic conference. The conference server  13  may pair the telephone device  11  and the conference terminal device  14  according to the pairing instruction. After the telephone device  11  has been paired with the conference terminal device  14 , the conference server  13  set the microphone of the telephone device  11  as an audio input device and set the speaker of the telephone device  11  as an audio output device while the electronic conference is being held. The conference server  13  controls the conference terminal device  14  to log in a user&#39;s electronic conference account according to the pairing instruction. Then, the conference server  13  transmits user&#39;s conference data to the conference terminal device  14 . The conference server  13  also transmits a conference instruction to the conference terminal device  14 . 
     After the conference terminal device  14  is connected with the conference server  13  in a wired or wireless way, the conference terminal device  14  logs in the conference server  13 . The conference terminal device  14  presents conference terminal recognition data. For example, the conference terminal device  14  is connected with a display device  15  and outputs to the display device  15  conference terminal recognition data corresponding to the conference terminal device  14 . After the conference terminal device  14  logs in the user&#39;s electronic conference account, the conference terminal device  14  outputs a graphic user interface (it will be explained while  FIG.  3    is mentioned). The graphic user interface shows the user&#39;s conference data and a plurality of conference instruction strings, wherein the plurality of conference instruction strings corresponds to a plurality of conference instructions. After the conference terminal device  14  receives the conference instructions from the conference server  13 , the conference terminal device  14  controls the electronic conference according to the conference instructions. 
       FIG.  2    shows a flowchart of a method of integrating a telephone device and controlling the electronic conference according to the first preferred embodiment of the present invention. Please refer to  FIG.  1    and  FIG.  2    simultaneously. The application of the devices will be explained in describing the flowchart below. It should be understood that the sequence of the steps may be changed, and some of the steps may be omitted according to requirements. 
     Firstly, in Step S 01 , present conference terminal recognition data of the conference terminal device  14 . In a conference room, the conference terminal device  14  may be a desktop computer or a notebook computer. In order to make the personnel in the conference room able to view the images clearly, the conference terminal device  14  may be connected with a display device  15 . The conference terminal device  14  is registered in the conference server  13  and will present on the display device  15  conference terminal recognition data corresponding to the conference terminal device  14 . The conference terminal recognition data may be a string composed of the numerals, letters, and symbols on the keyboard of the telephone device  11 , whereby the user may input data with the keyboard of the telephone device  11  while performing the pairing of the telephone device  11  and the conference terminal device  14 . For example, the display device  15  presents “*20008100” as the conference terminal recognition data. 
     In Step S 02 , operate the telephone device  11  to transmit pairing data to the telephone exchanger  12  according to the conference terminal recognition data. Because the user can see the conference terminal recognition data presented by the display device  15 , the user may operate the telephone device  11  to transmit the pairing data to the telephone exchanger  12 . In the embodiments of the present invention, the user may input the conference terminal recognition data, the user account, and the user password together with the pairing data, whereby to pair the telephone device  11  and the conference terminal device  14 . The user account and the user password are the account and password of a user in an electronic conference system of the conference server  13 , respectively. The user account and the user password are used for logging in the electronic conference system to retrieve the conference data of the user. For example, the user account is “*20008080”, and the user password is “*1234”. While the user intends to operate the telephone device  11  to input the conference terminal recognition data, the user account, and the user password simultaneously with the pairing data, “*20008100*20008080*1234” is inputted. 
     In another embodiment of the present invention, the user may only input an extension code as the pairing data at first. The extension code is used to enable the telephone exchanger  12  to trigger the execution of a special duty, such as the Interactive Voice Response (IVR) function. In one embodiment, the extension code may be “*200”. In the succeeding steps, the user further inputs the conference terminal recognition data, the user account, and the user password. While the telephone exchanger  12  receives the pairing data and verifies that the pairing data include the extension code “*200”, the telephone exchanger  12  performs the IVR service, whereby the user may input the conference terminal recognition data, the user account, and the user password according to the vocal instruction. In the embodiments of the present invention, the telephone device  11  may be a conventional analog-type telephone, which may transmit data to the telephone exchanger  12  in the DTMF format. 
     In Step S 03 , the telephone exchanger  12  converts the pairing data into a pairing instruction and transmits the pairing instruction to the conference server  13 . As mentioned above, the pairing data is sent to the telephone exchanger  13  by the telephone device  11  in the DTMF format. In order to make the conference server  13  able to receive and process the contents of the pairing data, the telephone exchanger  12  converts the pairing data, which is in the DTMF format, into the pairing instruction and then transmits to the conference server  13  the pairing instruction, which is in a format that can be received and processed by the conference server  13 . 
     In Step S 04 , the conference server  13  pairs the telephone device  11  and the conference terminal device  14  according to the pairing instruction. The pairing instruction received by the conference server  13  is originated from the telephone device  11 , and the pairing instruction includes the conference terminal recognition data, the user account, and the user password. After the account number and password have been successfully verified, the conference server  13  can pair the telephone device  11  with the conference terminal device  14 , whereby the operations that the user performs in the telephone device  11  are regarded as the inputs to the conference terminal device  14 . 
     In Step S 05 , the conference server  13  sets the microphone of the telephone device  11  as an audio input device and sets the speaker of the telephone device  11  as an audio output device. Since the conference server  13  has paired the telephone device  11  with the conference terminal device  14 , the conference server  13  may set the microphone of the telephone device  11  as an audio input device of the conference terminal device  14 . Thus, it is unnecessary to purchase an additional microphone as the audio input device of the conference terminal device  14  for electronic conferences. In other words, the present invention not only can save money for the user but also can exempt the original telephone device  11  from being idled. Similarly, the conference server  13  sets the speaker of the telephone device  11  as an audio output device of the conference terminal device  14 . Thus, it is unnecessary to purchase an additional speaker as the audio output device of the conference terminal device  14  for electronic conferences. 
     In Step S 06 , the conference server  13  controls the conference terminal device  14  to log in an electronic conference account of the user according to the pairing instruction. As the pairing instruction received by the conference server  13  includes the account number and password of the electronic conference account of the user, the conference server  13  can control the conference terminal device  14  to log in the electronic conference account of the user. 
     In Step S 07 , the conference server  13  transmits conference data of the user to the conference terminal device  14 . The conference data of the user includes all the schedules of the electronic conferences of the user and the contact list of the user. However, the present invention does not limit the conference data to only contain the abovementioned data. 
     In Step S 08 , the conference terminal device  14  outputs the conference data of the user. As mentioned above, the conference terminal device  14  may be connected with a display device  15  and outputs the conference data of the user to the display device  15 , whereby the user and the other attendees in the same conference room can view the images clearly. In one embodiment of the present invention, the conference terminal device  14  may output a graphic user interface, and the graphic user interface may present the conference data of the user and a plurality of conference instruction strings, wherein the plurality of conference instruction strings is respectively corresponding to a plurality of conference instructions. The conference instruction string is composed of the numerals, letters, and symbols on the keyboard of the telephone device  11 . In the embodiments of the present invention, the conference instructions may include an electronic conference entering instruction, an electronic conference leaving instruction, an attendee inviting instruction, an attendee quitting instruction, an attendee selecting instruction, a microphone activating instruction, a microphone deactivating instruction, a camera activating instruction, and a camera deactivating instruction. The graphic user interface will be further explained and exemplified thereinafter. 
     In Step S 09 , the user operates the telephone device  11  to transmit a conference instruction string to the telephone exchanger  12 . As mentioned above, in Steps S 01 -S 08 , the telephone device  11  has been successfully paired with the conference terminal device  14 ; the conference terminal device  14  outputs the conference data of the user; the graphic user interface presents a plurality of conference instruction strings. The user may input corresponding conference instruction strings to perform intended conference operations. For example, while the user intends to enter an electronic conference in Conference Room 1, the user operates the keyboard of the telephone device  11  to input a specified conference instruction string according to the conference instruction string prompted by the graphic user interface, whereby the specified conference instruction string is sent to the telephone exchanger  12  instantly. 
     In Step S 10 , the telephone exchanger  12  converts the conference instruction string into a conference instruction and transmits the conference instruction to the conference server  13 . As mentioned above, the conference instruction string is sent to the telephone exchanger  13  by the telephone device  11  in the DTMF format. In order to make the conference server  13  able to receive and process the contents of the conference instruction string, the telephone exchanger  12  converts the conference instruction string, which is in the DTMF format, into a conference instruction and then transmits to the conference server  13  the conference instruction, which is in a format that can be received and processed by the conference server  13 . 
     In Step S 11 , the conference server  13  transmits the conference instruction to the conference terminal device  14 . The conference terminal device  14  executes the conference instruction in practice. Therefore, the conference server  13  transmits the conference instruction to the conference terminal device  14 . 
     In Step S 12 , the conference terminal device  14  controls the electronic conference according to the conference instructions. Suppose the conference instruction string, which the user inputs to the telephone device  11 , is “entering the electronic conference in Conference Room 1”. While the conference terminal device  14  receives the conference instruction “entering the electronic conference in Conference Room 1”, which is transmitted by the conference server  13 , the conference terminal device  14  enters the electronic conference in Conference Room 1. Suppose the conference instruction string, which the user inputs to the telephone device  11 , is “closing the microphone”. While the conference terminal device  14  receives the conference instruction “closing the microphone”, which is transmitted by the conference server  13 , the conference terminal device  14  closes the microphone. How the user controls the electronic conference in cooperation with the graphic user interface will be further explained thereinafter. 
       FIG.  3    schematically shows a graphic user interface output by a conference terminal device according to a preferred embodiment of the present invention. The graphic user interface in  FIG.  3    includes the conference data of the user and a plurality of conference instruction strings. The conference data of the user further includes electronic conference schedules and a contact list of the user. As shown in  FIG.  3   , after the conference server  13  transmits the conference data of a user to the conference terminal device  14  and the conference terminal device  14  outputs the conference data of the user, the user may use the keyboard of the telephone device  11  to input the conference instruction string to perform a special operation of the electronic conference referring to the electronic conference schedules shown in the graphic user interface. Suppose that the user intends to enter Conference Room 1 for an electronic conference. In the graphic user interface, Conference Room 1 is expressed by “N=1”, and the conference instruction string of “entering the electronic conference” is “*21*N”. Thus, the user will enter Conference Room 1 for an electronic conference merely by using the keyboard of the telephone device  11  to input “*21*1”, wherein the last code “1” denotes Conference Room 1. Suppose that the user intends to close the microphone after entering Conference Room 1. The conference instruction string for closing the microphone is “*27”. Thus, the user can close the microphone merely via using the keyboard of the telephone device  11  to input “*27”. Suppose that the user intends to invite Bob in the contact list to enter Conference Room 1 after the user has entered Conference Room 1. In the graphic user interface, Bob is expressed by “M=2”, and the conference instruction string of “inviting a person as an attendee” is “*35*M”. Thus, the user can invite Bob to enter Conference Room 1 merely via using the keyboard of the telephone device  11  to input “*35*2”, wherein the last code “2” denotes Bob. It should be understood that the graphic user interface in  FIG.  3    is only for exemplification, and the present invention is not limited by the exemplification. 
       FIG.  4    schematically shows a system architecture wherein a telephone device is integrated with an electronic conference system according to a second preferred embodiment of the present invention.  FIG.  5    shows a flowchart of a method of integrating a telephone device and controlling the electronic conference according to the second preferred embodiment of the present invention. In the embodiment shown in  FIG.  4    and  FIG.  5   , a conventional telephone exchanger is integrated into the system of the present invention, wherein the conventional telephone exchanger is unable to convert the data in the DTMF format into the data in the format that the conference server  13  can receive and process. Refer to  FIG.  4    and  FIG.  5    simultaneously while reading the description of the second preferred embodiment. 
     In  FIG.  4   , a system  20  comprises a telephone device  21 , a first telephone exchanger  221 , a second telephone exchanger  222 , a conference server  23 , and a conference terminal device  24 . The telephone device  21  is in signal connection with the first telephone exchanger  221 ; the first telephone exchanger  221  is in signal connection with the second telephone exchanger  222 ; the second telephone exchanger  222  is in signal connection with the conference server  23 ; the conference server  23  is connected with the conference terminal device  24  in a wired or wireless way. A display device  25 , which does not belong to the system  20 , is connected with the conference terminal device  24  to make the attendees in the conference room able to view the images. By comparing  FIG.  4    with  FIG.  1   , the function of the telephone device  21  is similar to the function of the telephone device  11 ; the function of the second telephone exchanger  222  is similar to the function of the telephone exchanger  12 ; the function of the conference server  23  is similar to the function of the conference server  13 ; the function of the conference terminal device  24  is similar to the function of the conference terminal device  14 . Therefore, the abovementioned devices of the second preferred embodiment will not be described repeatedly herein. 
     The first telephone exchanger  221  may be a conventional telephone exchanger, which is unable to convert the DTMF-format data into the data that the conference server  23  can receive and process. In order to integrate the first telephone exchanger  221  into the system  20  of the present invention, a routing rule is established in the first telephone exchanger  221 . The routing rule includes a preset code and a line. After the first telephone exchanger  221  receives and verifies the preset code, the first telephone exchanger  221  transmits data to the second telephone exchanger  222  via the line. The line is a physical circuit connecting the first telephone exchanger  221  with the second telephone exchanger  222 . The operation of the system  20  in  FIG.  4    will be further explained thereinafter. 
       FIG.  5    shows a flowchart of a method of integrating a telephone device and controlling the electronic conference according to the second preferred embodiment of the present invention. Firstly, in Step S 10 , establish a routing rule in the first telephone exchanger  221 . The routing rule includes a preset code (such as *00) and a line. The line is a physical circuit for signal connection between the first telephone exchanger  221  and the second telephone exchanger  222 . 
     In Step S 02 , present conference terminal recognition data of the conference terminal device  24 . The conference terminal device  24  may be a desktop computer or a notebook computer. A display device  25  is connected with the conference terminal device  24  to make the persons in the conference room able to view the images. The conference terminal device  24  is registered in the conference server  23  and will present on the display device  25  conference terminal recognition data corresponding to the conference terminal device  24 . 
     In Step S 03 , operate the telephone device  21  to transmit pairing data to the first telephone exchanger  221  according to the conference terminal recognition data. The pairing data include a preset code and an extension code. The preset code is to be verified by the first telephone exchanger  221 . After the first telephone device  221  has verified the preset code, the first telephone exchanger  221  transmits succeeding data to the second telephone exchanger  222 . The extension code is used to make the second telephone exchanger  222  trigger the execution of a special duty, such as an Interactive Voice Response (IVR) function. In one embodiment, the user operates the telephone device  21  to input a preset code “*00” and an extension code “*200”. 
     In Step S 04 , after the first telephone exchanger  221  has received pairing data and verified that the pairing data include the preset code “*00” and the extension code “*200”, the first telephone exchanger  221  transmits the extension code “*200” through the line to the second telephone exchanger  222  according to the routing rule. 
     In Step S 05 , after receiving the extension code “*200”, the second telephone exchanger  222  performs the IVR function to make the user operate the telephone device  21  to input the conference terminal recognition data, the user account, and the user password to the second telephone exchanger  222 . 
     In Step S 06 , the second telephone exchanger  222  converts the conference terminal recognition data, the user account, and the user password into a pairing instruction and transmits the pairing instruction to the conference server  23 . As mentioned above, the telephone device  21  transmits the conference terminal recognition data, the user account, and the user password in the DTMF format to the second telephone exchanger  222 . In order to make the conference server  23  able to receive and process these data, the second telephone exchanger  222  converts the DTMF-format data into the pairing instruction and then transmits the pairing instruction to the conference server  23 , wherein the pairing instruction is in a format that the conference server  23  can receive and process. 
     In Step S 07 , the conference server  23  pairs the telephone device  21  with the conference terminal device  24  according to the pairing instruction, whereby the operation that the user performs in the telephone device  21  is regarded as the input to the conference terminal device  24 . 
     In Step S 08 , the conference server  23  sets the microphone of the telephone device  21  as an audio input device and sets the speaker of the telephone device  21  as an audio output device. As mentioned above, as the conference server  23  has paired the telephone device  21  with the conference terminal device  24 , the conference server  23  may set the microphone and the speaker of the telephone device  21  as the audio input device and the audio output device, respectively. Thus, it is unnecessary to purchase an additional microphone and an additional speaker as the audio input device and the audio output device. In other words, the present invention can save money for the user and exempt the original telephone device  21  from being idled. 
     In Step S 09 , the conference server  23  controls the conference terminal device  24  to log in a user&#39;s electronic conference account. As the pairing instruction received by the conference server  23  includes a user account and a user password of an electronic conference account, the conference server  23  can control the conference terminal device  24  to log in the user&#39;s electronic conference account. 
     In Step S 10 , the conference server  23  transmits the conference data of the user to the conference terminal device  24 , wherein the conference data of the user may include the schedule data of all the electronic conferences of the user and the contact list of the user. However, the present invention does not limit the conference data to only the schedule data and the contact list. 
     In Step S 11 , the conference terminal device  24  outputs the conference data of the user. As mentioned above, the conference terminal device  24  may be connected with a display device  25  and output the conference data of the user to the display device  25 , whereby the user and the other attendees in the same conference room can view the images clearly. The conference terminal device  24  may output a graphic user interface, which presents the conference data of the user and a plurality of conference instruction strings, wherein the plurality of conference instruction strings is respectively corresponding to a plurality of conference instructions. 
     In Step S 12 , operate the telephone device  21  to transmit the preset code and a conference instruction string to the first telephone exchanger  221 . In Steps S 01 -S 11 , the telephone device  21  has been successfully paired with the conference terminal device  14 ; the conference terminal device  24  outputs the conference data of the user; the graphic user interface presents a plurality of conference instruction strings. Thus, the user may input corresponding conference instruction strings for the intended operations of the electronic conference. In Step S 01 , the preset code and the line of the routing rule have been established in the first telephone exchanger  221 . Therefore, the user can transmit the conference instruction string merely via inputting the preset code and the conference instruction string to the first telephone exchanger  221 . 
     In Step S 13 , while the first telephone exchanger  221  receives and verifies the preset code and the conference instruction string, the first telephone exchanger  221  transmits the conference instruction string through the line to the second telephone exchanger  222  according to the routing rule. 
     In Step S 14 , the second telephone exchanger  222  converts the conference instruction string into a conference instruction and transmits the conference instruction to the conference server  23 . As the conference instruction string is transmitted from the telephone device  21  to the first telephone exchanger  221  and then to the second telephone exchanger  222  in the DTMF format, the second telephone exchanger  222  converts the DTMF-format conference instruction string into the conference instruction and transmits the conference instruction to the conference server  23 . The conference instruction is a format that the conference server  23  can receive and process. 
     In Step S 15 , the conference server  23  transmits the conference instruction to the conference terminal device  24 . Because the conference terminal device  24  executes the conference instruction in practice, the conference server  23  transmits the conference instruction to the conference terminal device  24 . 
     In Step S 16 , the conference terminal device  24  controls an electronic conference according to the conference instruction. If the conference instruction string the user inputs in the telephone device  21  is “entering Conference Room 1 for the electronic conference”, the conference terminal device  24  will receive the conference instruction “entering Conference Room 1 for the electronic conference” transmitted by the conference server  23 . Then, the conference terminal device  24  enters Conference Room 1 for the electronic conference. If the conference instruction string the user inputs in the telephone device  21  is “closing the microphone”, the conference terminal device  24  will receive the conference instruction “closing the microphone” transmitted by the conference server  23 . Then, the conference terminal device  24  closes the microphone. 
     In conclusion, the present invention proposes a method of integrating a telephone device and controlling the electronic conference, which can exempt the original telephone device from being idled and wasted while the user upgrades the electronic conference apparatuses. Further, the method of integrating a telephone device and controlling the electronic conference of the present invention enables the original telephone device to function as a control platform of an electronic conference. Besides, the method of integrating a telephone device and controlling the electronic conference of the present invention can integrate a conventional telephone exchanger with another telephone exchanger, whereby the conventional telephone exchanger transmits a DTMF-format data to the another telephone exchanger according to a routing rule, and the another telephone exchanger converts the DTMF-format data into a data having a format that the conference server can receive and process.
