PROBLEM TO BE SOLVED: To prevent unpleasant feeling from being given to the user of the other terminal by executing holdings without permission when holding is executed in its own terminal during the holding of the other terminal. SOLUTION: A holding start detection part 113 detecting that the other terminal is in a holding state, its own terminal accumulation part 116 accumulating information of a reason for executing holding in its own terminal when the other terminal is in the holding sate, holding release detection part 114 detecting that the other terminal releases the holding state and a transmission control part 117 transmitting the accumulated content of its own terminal accumulation part 116 to the other terminal after holding in the other terminal is released are provided. When the other terminal is in the holding state, reason information is temporarily accumulated in its own terminal accumulation part 116 before holding is actually started in its own terminal, and accumulation information is transmitted and reproduced after the holding of the other terminal is released. Thus, a holding standby state and the sudden cut of a line can be eliminated immediately after the release of holding by the other terminal. |
