The receiving side IP terminal 6 that has received the connection instruction is instructed to connect to the receiving side IP terminal 6 waiting for the included telephone number via the IP network 1 and the network interface means 15 according to the information of the communication control parameter. 6 performs a connection process with the transmission side IP terminal 3 in accordance with the contents of the connection instruction. Continued, and starts the dummy data communication by transmitting and receiving dummy data to and from the transmission side IP terminal 4 and the receiving-side IP terminal 6 (step 61).

  Through this dummy data communication, the IP terminals 4 and 6 in the dummy data communication obtain network traffic information such as packet loss, delay fluctuation amount, connection path information and the like and notify the IP terminals 3 and 5 (step 62).

  The obtained network traffic information is stored in the storage monitoring means 19, and the traffic state of the IP network 1 is monitored based on the network traffic information (step 63).

  Then, communication control parameters for voice communication are determined from the storage monitoring information of the IP network 1 (step 64). For example, the network interface means 15 and the IP network 1 are used to perform voice communication from the transmission side IP terminal 3. Call control information (information such as on-hook, off-hook, destination telephone number, hold, transfer, etc.) and information on determined communication control parameters (type of voice compression, fluctuation buffer amount, packetization period, silence compression, etc.) According to the instruction of the means 21, it is transmitted to the IP-PBX 2 (step 65).

  The IP-PBX 2 instructs the receiving side IP terminal 5 of the other party telephone number included in the call control information to connect according to the information of the communication control parameter via the IP network 1 and the network interface means 15, and issues a connection instruction. The receiving side IP terminal 5 that has received the connection process is connected to the transmitting side IP terminal 3 in accordance with the contents indicated by the connection instruction (step 66), and voice is transmitted between the transmitting side IP terminal 3 and the receiving side IP terminal 5. Communication is started (step 67).

  Here, the IP terminals 3 and 5 that are waiting in the step obtain network traffic information such as packet loss, delay fluctuation amount, connection path information, and the like of the IP terminals 3 and 5 through dummy data communication. Step 62 for notifying information to the IP terminals 4 and 6 and step 63 for accumulating and monitoring the network traffic information are accumulating and monitoring steps in the fourth embodiment. Is a communication control step in the fourth embodiment, and step 66 of performing connection control signaling to the IP-PBX 2 in response to the determination of the communication control parameter is the signaling step.
