If off-hook is detected, the two-way call between the user and the other party is performed. Is started (step 51). Then, after starting the two-party call, the call control unit 16 detects on-hook (step 81), and when the on-hook is detected, ends the two-party call between the user and the other party.

  In step 2, when the determination unit 14 determines that the telephone number is not reliable, the warning notification unit 15 notifies the user of a warning by displaying a warning screen 17 on the touch panel 11 (step 3). The call control unit 16 detects off-hook after the warning is notified to the user by the warning notification unit 15 (step 42). When the off-hook is detected, the two-way call between the user and the other party is started. (Step 52). Then, the call control unit 16 determines whether or not the operation button 17B has been pressed after starting the two-party call (step 6). When it is determined that the operation button 17B is not pressed, the call control unit 16 performs on-hook detection (step 82). When the on-hook is detected, the two-way call between the user and the other party is terminated. If no on-hook is detected, step 6 is executed again.

  If it is determined in step 6 that the operation button 17B has been pressed, the call control unit 16 starts a three-way call between the user, the other party, and a third party (step 7). Specifically, when the operation button 17B is pressed, the call control unit 16 puts the two-party call between the user and the other party on hold, and the telephone number with the highest priority in the third party list 12A (priority order 1). Call a third party based on the phone number). When the call control unit 16 can start a call with the third party, the call control unit 16 cancels the hold of the two-party call between the user and the other party, thereby allowing the user, the other party, and the third party to A person call. If the call control unit 16 cannot start a call with the third party, the call control unit 16 calls the third party based on the next highest priority telephone number (second highest priority telephone number). In this way, the call control unit 16 calls third parties one after another according to the priority order until a three-party call is started. As a result, the user can reliably call a third party and start a three-way call during a call with the other party. Note that the call control unit 16 determines that a call with a third party cannot be started by detecting a busy tone or detecting a ringing tone more than a predetermined number of times.

  Then, the call control unit 16 detects the on-hook after starting the three-party call (step 81). When the on-hook is detected, the call control unit 16 ends the three-way call between the user, the other party, and the third party. To do.

  Thus, according to the first embodiment, the three-way communication device 1 can be trusted by the determination unit 14 that determines whether or not the caller number is a phone number that can be trusted by the user, and the determination unit 14. If it is determined that the number is not a telephone number, the call control unit 16 starts a multi-party call with the user, the other party, and a third party. 3 parties including this third party can be called. Therefore, since the third party can confirm the content of the call during a call with the other party that cannot be trusted by the user, the user can be prevented from being scammed, and the damage caused by crime can be prevented appropriately.
