<p><P>PROBLEM TO BE SOLVED: To provide a call test system by which an appropriate test can be performed for an IP terminal from a remote place without increasing cost of each terminal. <P>SOLUTION: An initiating side IP terminal and a receiving side IP terminal are each equipped with a switch connected with each other and a test server 1 connectable to these switches via a network. The test server is equipped with a test call producing means for giving instructions to each of the switches to switch the connection with the initiating side IP terminal 21, or with the receiving side IP terminal 22 to the connection with the test server to perform, by transmitting call test signals, the call test of whether being connectable or not between each of the switches connected with the test server; and a connection switch setting means for setting, in response to a connection switching instruction from the test server, for each switch to switch the connection with the initiating side IP terminal 21, or with the receiving side IP terminal 22 to the connection with the test server. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
