The utility model relates to a dispatching soft-exchange system for power communication, aiming at solving the problem that the existing dispatching exchange systems do not have the function of multi-party video conference. The system comprises a video terminal, a calling processor for providing point-to-point video calling, a voice gateway connected with the video terminal and the calling processor, and MCU (microprogrammed control unit) equipment connected with the voice gateway. The MCU equipment plays a role of core leading equipment in a video conference; therefore, the function of multi-party video conference can be provided via the MCU equipment. Additionally, because point-to-point video conversation can be provided via voice, the soft-exchange system for power communication disclosed by the embodiment of the utility model can support the point-to-point video conversation and the multi-party video conference simultaneously.
