Zusammenfassung:PROBLEM TO BE SOLVED: To provide a media communication system that can avoid deterioration in voice quality in VoIP(Voice over IP) communication even when a span (e.g. a wireless span) having no sufficient data transmission band exists. SOLUTION: The media communication system is provided with an IP packet processing section 150 that assembles a media signal transmitted from a terminal into an IP packet, transmits the IP packet to an IP network and converts the IP packet received from the IP network into the media signal and with a media signal transmission section 160 that connects a media signal processing section 122 provided in the terminal to the IP packet processing section to transmit the media signal. The terminal 103 controls the IP packet processing section 150 to act like its own IP packet processing section on the occurrence of a call and controls the media signal transmission section 160 to connect the media signal processing section 122 and the IP packet processing section 150 to attain the transmission of the media signal, and transmits/receives the media signal to/from a terminal 102 via the media signal processing section 122, the media signal transmission section 160, the IP packet processing section 150 and the IP network 130 after terminating the connection.
