The softswitch, assimilating voice, video and data services into a uniform framework, has been deployed in a smart power dispatch center. The power dispatch managing video conference helps to slove emergent situations happened in grid. Firstly, this paper introduces architecture of SIP video conference based on concentrative and high coupling model and concept of SIP, MSML and so on. Secondly, it presents the basic signaling flow of a video conference. Finally, it discusses the architecture of a video conference server based on SIP and the design and implementation of main modules.
