At the start of a communication, a video and audio output other than the communication is automatically turned off. When a handset is off-hooked or the operation to start the communication is performed by an operation apparatus, a communication control circuit switches a change-over switch to an a contact and turns off a disconnecting switch. When the handset is on-hooked or the operation to finish the communication is executed by the operation apparatus, the communication control circuit switches the change-over switch to a b contact and turns on the disconnecting switch.
