System and method for controlling a transfer call |
摘要 |
<p>To provide a transfer control system that allows a call to be retransferred by a command from a source communication terminal and is capable of improving the convenience of a user issuing the command. In-communication information describing that a second terminal and a third terminal are now in communication with each other after a call is transferred in a state where a first terminal and the second terminal are in communication with each other is stored in a call state storage device. When a retransfer command is issued by the first terminal, the call is transferred to a fourth terminal by referring to the in-communication information stored in the call state storage device, thereby establishing communication between the second terminal and the fourth terminal. <IMAGE></p> |
