RealPresence Desktop and CoS/QoS

A user is experiencing is experiencing the jitters, pixilation, etc. with both audio and video. I did notice that the packet loss percentage for the 1011 People Rx would bounce around – mostly close to 0% but occasionally spiking as high as 30%.


I am pretty sure I know what the issue may be. I suspect it is a QoS/CoS issue in either our LAN, WAN or both.


We know that Video conferencing requires the correct QoS/CoS (Class of Service) settings. Desktop connections may not have the end to end QoS/CoS settings correct. That is the first place we need to start. To me the  symptoms point to QoS/CoS as not be configured correctly.


However, I can find nothing regarding how RealPresence Desktop utilizes or even how to configure the settings. Can someone point me to the correct QoS/CoS settings for RealPresence Desktop


I have been told they are just installed with the defaults. I downloaded the trial software and did not even see a place to configure the QoS/CoS settings.
