  However, the redial function as described above stores only the history of incoming calls. Therefore, the fixed telephone terminal 80 is the target of contact using the redial function.

  In recent years, signals of various signal types are also used for telephone terminals. For example, in the case of a videophone terminal, an audio signal and an image signal are used. Furthermore, there are various types of codec capabilities even for the same audio signal and image signal. However, the incoming call history does not include signal type or codec capability information.

  Therefore, when redialing, the user redials without knowing the signal type and codec capability of the other party's telephone terminal. As a result, it is inevitable that the user transmits with a signal type different from the signal type of the other party's telephone terminal, or transmits with a codec capability mismatch even if the signal types match.

  Communication between telephone terminals with different signal types is difficult. In addition, if the codec capabilities do not match even between telephone terminals having the same signal type, negotiation processing of the codec capability occurs. Such negotiation processing is not preferable for effective use of the communication network because it causes a load on the communication network.

  The present invention has been made under such a background, and an object thereof is to provide a key telephone device, a redial control method, and a program capable of realizing efficient redial processing.

Next, the operation of the key telephone device 1 will be described. The call control unit 2 recognizes that the incoming call is addressed to the telephone terminal 11 by analyzing incoming information included in the incoming call, and connects the incoming call to the telephone terminal 13 (step S1). At this time, when detecting that the telephone terminal 11 is not responding (step S2), the call control unit 2 sends an automatic voice response instruction to the IVR control unit 5 (step S3). The IVR control unit 5 performs an automatic voice response in accordance with the automatic voice response instruction from the call control unit 2 (step S4). The content of the automatic voice response message sent from the IVR control unit 5 is, for example, “I can't answer the phone now. Please enter the phone number or address you want to contact.” Further, in the automatic voice response sent from the IVR control unit 5, a message such as “terminal type, media type, and codec capability can be input” is sent after this message.

  The user of the fixed telephone terminal 20 listens to the contents of the automatic voice response and inputs the telephone number or address for which contact is desired. As a method for the user to input a telephone number or an address, a conventionally widely used method such as using a push button signal can be used.

  For example, “1” is input for a fixed phone, “2” is input for a mobile phone, “3” is input for a computer terminal, and “4” is input otherwise. Please. " For example, “1” is input for audio, “2” is input for an image, and “3” is input for other cases. For example, “1” if the audio codec is G.711, “2” if Umclip (mU-law Embedded Coder for low-delay IP Communication), and “0” otherwise. Enter “3”, “4” if the image codec is Mpeg2 (Moving picture experts group phase2), “5” if Mpeg4 (Moving picture experts group phase4), and “6” otherwise. ”

  When the user of the fixed telephone terminal 20 inputs various types of information in response to the automatic voice response from the IVR control unit 5, these various types of information are accepted by the call control unit 2 as redial information (step S5). The call control unit 2 stores the redial information received from the fixed telephone terminal 20 in the incoming call history storage unit 3 together with the incoming call history (step S6). The display control unit 4 displays the stored contents of the incoming call history storage unit 3 not only on the telephone terminal 11 but also on the other telephone terminals 10 and computer terminals 12 accommodated in the key telephone device 1 (step S7).

If there is an incoming call in the call control unit 2 (step S10) and there is a response to this incoming call (No in step S11), communication is started (step S20). However, if there is no response to the incoming call (Yes in step S11), the call control unit 2 sends an automatic voice response instruction to the IVR control unit 5 (step S12). The IVR control unit 5 performs an automatic voice response in accordance with the voice automatic response instruction from the call control unit 2, and if there is an input of redial information for this voice automatic response (Yes in step S13), the call control unit 2 stores the redial information in the incoming call history storage unit 3 together with the incoming call history. The display control unit 4 displays redial information stored in the incoming call history storage unit 3 (step S14). At this time, if there is no input of redial information (No in step S13), the call control unit 2 stores only the incoming call history in the incoming call history storage unit 3. Further, the display control unit 4 displays the incoming call history stored in the incoming call history storage unit 3 (step S21).

  Here, when the user performs a redial operation (Yes in step S15) and a redial destination is specified (Yes in step S16), the call control unit 2 transmits to the redial destination (step S17). If the redial destination responds (Yes in step S18), the redial control process in the call control unit 2 ends. However, if the redial destination does not respond (No in step S18), the call control unit 2 returns to step S16 to continue waiting for the designation of the redial destination, and there is a response in steps S16 and S17 in step S18. (Yes in step S18) and repeat. If the redial destination is not specified (No in step S16) and the process is stopped (Yes in step S19), the redial control process in the call control unit 2 is terminated.

  Next, FIG. 3 shows the flow of processing when the incoming caller and contact are different. In the example of FIG. 3, the fixed telephone terminal 20 is the caller of incoming calls, while the mobile telephone terminal 21 is the contact address.
