Gohigh data network LTD and Radvision announced a new Voice and Video over broadband internet solution in Nov. 28th 2008.
该方案基于大唐高鸿的运营商级软交换平台SS3000－T。SS3000－T下的所有注册用户均可以通过自己的视频终端访问视频会议中心，该视频会议中心使用了Radvison的Scopia MCU。
This solution is based on Gohigh’s carrier grade softswitch system SS3000-T. All subscribers under SS3000-T can access to the video conference center by using their video terminals. This video conference center uses the scopia MCU from Radvision.
对于SS3000－T电话用户，只需要将终端改为视频终端，或者安装个像xlite这样的免费软电话，在PC机上装个摄像头，就可以进行视频通话了；拨打视频会议接入号，就可以加入视频会议。
For those telephone users, they just need to change to a video terminal like a free software phone x-lite and a camera on their pc. After that, they can make video calls in this network. And when they dial the video conference access number, they can take part into the video conference.
