We have a problem in a group RealPresence 500. When calls are made between the Group RealPresence HDX 7000 and belonging to different networks, the video for the Group 500 is black and no audio. But the HDX 7000 receives audio and video. The same happens when carried out calls between RealPresence Group and an iPad with RealPresence Desktop installed. The problem does not persist when the RealPresence Group 500 calls a LifeSize icon and also does not occur any problem when we turn between Icon LifeSize and HDX 7000.
Please could you help us? It is what could be the firewall? most like to ask which ports should be released to the RealPresence Group 500?
