We have a couple Cisco SX20 video conferencing units.  They had up until this semester been working fine.  This semester we are experiencing high packet loss outbound only (we can see and hear everyone fine but they get jitter and dropped audio).  We have tried a bunch of things to fix the problem, but nothing seems to work.  I am curious what usually causes this level of loss (anywhere from 6 to 20 % packet loss that goes up and down during the course of a call).  

I have updated the firmware to the latest version 9.9.2, added QOS to the uplink port on the Cisco switch stack it connects to, and tired a multitude of things to get this working.  Very frustrating for the distance learning they are trying to do.  Any thoughts or suggestions would be appreciated.
