A portable telephone (100) includes: a voice input section (108); a voice output section (106,107); an interface (103) required to connect the portable telephone to an external device (200) for making a handsfree phone call; and a control section (113), wherein when a failure occurs in the connection between the portable telephone and the external device while the handsfree phone call is made via the interface, the control section changes a phone call process from the handsfree phone call via the interface to a handsfree phone call by the voice input section and the voice output section. |
