When the selection input for the area for call path switching is received from the user, the control unit 170 may control the display unit 140 to output the call path switching user interface. However, it is only an example that the area for call path switching is outputted on one side of the screen and the user interface is outputted on the basis of the selection of the output area. Accordingly, It is possible to control the output of the user interface for call path switching in the call state without outputting the area.

In step 205, the control unit 170 can search for peripheral Bluetooth devices around the portable electronic device 100 when the selection input for the user interface for the call path switching is received.
