A communication apparatus outputs data received from another communication apparatus. The communication apparatus includes: a notification unit that notifies an external information processing apparatus of an output state of data received from the other communication apparatus; and a display processing unit that, while a session for receiving data with the other communication apparatus is established, acquires an output state of data transmitted to the other communication apparatus at the other communication apparatus from the information processing apparatus and displays output state information representing the acquired output state on a display device.
