PROBLEM TO BE SOLVED: To provide an IP phone and an IP phone speech method whereby when the IP phone once makes call connection to a destination, the IP phone can transmit image information and information such as file data to the same destination while making a speech without making a callback. SOLUTION: The IP phone makes call connection to an IFAX function attached IP phone 110 being a speech opposite party via the Internet 103. The IP phone executes speech processing for transmitting/receiving a voice packet to/from the IFAX function attached IP phone 110 to which the IP phone makes call connection. In the case of transmitting an image to the IFAX function attached IP phone 110, during the IP phone makes a speech with the IFAX function attached IP phone 110, the IP phone generates an IFAX packet whose destination is set to the IFAX function attached IP phone 110, and transmits the IFAX packet to the Internet 103 while prioritizing the transmission of the voice packet.
