Disclosed herein is a method of monitoring 3G video telephony through a DM port. The method is performed using monitoring equipment in a state in which the monitoring equipment, provided with a driver module capable of opening the DM port of a mobile communication terminal for measurement, is connected to the mobile communication terminal. The method includes the steps of (a) opening the DM port of the mobile communication terminal, (b) setting up connection between the mobile communication terminal and a counterpart terminal by sending a key press command through the DM port, (c) sending H.324M protocol-based log commands through the DM port in order to receive voice or video data from the counterpart terminal, and receiving the voice or video data from the mobile communication terminal, (d) decoding and decompressing payload data of the received voice or video data, and (e) analyzing the decompressed voice or video data.
