Abstract:
There is provided a multifunction peripheral (MFP) configured to perform data communication using a session initiation protocol (SIP) server, which includes a main controller and a sub controller. The sub controller performs a 100Trying response as to a received INVITE, and also instructs activation of the main controller. Also, the main controller performs a 180Ringing response following the 100Trying after activation in response to the instruction from the sub controller, and performs data communication using a session established between the main controller and a partner device.
