Abstract

An MAC address of each of devices under testing is entered. An IP address is assigned to each entered MAC address. The IP addresses and telephone numbers assigned to the devices and a failure test terminal are associated with one another and registered in a system server. Out of telephones connected to the devices, 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 connected to the failure test terminal is tried. Thereby, adequate test on a large number of devices with simple operation is possible in performing an operation test on a VoIP device.

Claims

1. A test system for performing, in a batch, an operation test of a plurality of VoIP devices as devices under test capable of converting voice signals into packet data and transmitting and receiving the packet data for making telephone conversations through an IP network, said test system comprising:

a fixed address input unit used to input fixed address information which is uniquely given to the respective devices under test and physically fixed;

a DHCP unit operable to assign a dynamic address which is unique and dynamic to each fixed address input through said fixed address input unit;

a test device to which said dynamic address and a telephone number are fixedly assigned;

a call agent unit operable to register said dynamic address and the telephone number assigned to each of the respective devices under test and test device in association with each other; and

a plurality of telephone equipments connected to said devices under test and said test device respectively and capable of making telephone conversations from one to another through said call agent,

wherein an arbitrary two equipments are paired from among the plurality of the telephone equipments connected to the devices under test respectively, and

wherein a call is attempted from a first telephone equipment connected to one device under test of each pair to a second telephone equipment connected to another device under test of the pair, and if a telephone conversation is established, a call is attempted from said second telephone equipment which is called to said first telephone equipment, but if a telephone conversation is not established, a call is attempted to the telephone equipment connected to said test device.

2. The VoIP device test system as claimed in claim 1 wherein the telephone equipment connected to each of said devices under test is set up in order to make it possible to perform an abbreviated operation for dialing the telephone number which is the telephone number of the telephone equipment connected to another device under test to be called and registered in said call agent unit.

3. The VoIP device test system as claimed in claim 1 wherein 10 said fixed address input unit is a bar-code reader.

4. The VoIP device test system as claimed in claim 1 further comprising a monitor unit operable to monitor establishment of connection by transmitting a connection confirmation signal to a dynamic address which is assigned by said DHCP unit and receiving a response to this connection confirmation signal.

5. The VoIP device test system as claimed in claim 1 further comprising an upgrade unit operable to rewrite a program stored in a storage device of each device under test by the use of the dynamic address as assigned by said DHCP unit.

6. The VoIP device test system as claimed in claim 1 wherein said VoIP device is provided with a communication port for data communication which is provided separate from said communication port for telephone conversation, and further comprising a data communication test unit operable to transmit and receive data through said communication port for data communication and perform operation check of said communication port for data communication.

7. A test method performing, in a batch, an operation test of a plurality of VoIP devices as devices under test capable of converting voice signals into packet data and transmitting and receiving the packet data for making telephone conversations through an IP network, said test method comprising:

inputting fixed address information which is uniquely given to the respective devices under test and assigning dynamic addresses to the fixed addresses;

registering said dynamic address and the telephone number assigned to each of the respective devices under test in association with each other in a call agent unit, and registering said dynamic address and the telephone number assigned to a test device in said call agent unit; and

pairing an arbitrary two equipments from among a plurality of telephone equipments connected to the devices under test respectively, and attempting a call from a first telephone equipment connected to one device under test of each pair to a second telephone equipment connected to another device under test of the pair, wherein if a telephone conversation is established, a call is attempted from said second telephone equipment which is called to said first telephone equipment, but if a telephone conversation is not established, a call is attempted to the telephone equipment connected to said test device.

8. The VoIP device test method as claimed in claim 7 wherein, in said pairing, the telephone equipment connected to each of said devices under test is set up in order to make it possible to perform an abbreviated operation for dialing the telephone number which is the telephone number of the telephone equipment connected to another device under test to be called and registered in said call agent unit.

9. The VoIP device test method as claimed in claim 7 wherein said VoIP device is provided with a communication port for data communication which is provided separate from said communication port for telephone conversation, and further comprising transmitting and receiving data through said communication port for data communication and performing operation check of said communication port for data communication.
