<p>An MAC address of each device 8a to 8c under test is entered. An IP address is assigned to each entered MAC address. The IP addresses and telephone numbers assigned to the devices 8a to 8c and a failure test terminal 17 are associated with one another and registered in a system server 4. Out of telephones 10a to 10c connected to the devices 8a to 8c, sets of two telephones are determined. For each set, a call is made from a first telephone connected to the device to a second telephone connected to another device. When the communication is established, a call is made from the called second telephone to the first telephone. If the communication is not established, communication with a telephone 10d connected to the failure test terminal 17 is tried. With this, adequate test on a large number of devices with simple operation is possible in performing an operation test on a VoIP device.</p> |
