There is provided a communication apparatus that determines whether transmission of data to a transmission destination by a communication function satisfies a predetermined condition concerning data transmission, and controls the communication function such that upon determining that the predetermined condition is satisfied, a signal that does not include the data is transmitted to the transmission destination, and upon determining that the predetermined condition is not satisfied, a signal including the data is transmitted to the transmission destination. If a response to instruct transfer of the signal from the transmission destination to another transmission destination is received in accordance with the transmission of the signal to the transmission destination, the communication apparatus controls the communication function such that the signal including the data is transmitted to the other transmission destination.
