QoS in Windows for Webex BroadWorks: QoS for Webex for Broadworks is done by means of DSCP. AF46 for Audio en AF34 for Video. These settings can be changed using Costum Tags:
%AUDIO_QOS_VALUE_WXT% value 46 (default)
%VIDEO_QOS_VALUE_WXT% value 34 (default)
Note that when changed this needs also be changed in the Group Policies for Windows ADM files or ADMX files. Or in Microsoft Intune.
Windows needs Registry changes.
This can be done in several ways.
Windows Registry file:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\QoS\WebexAppAudioDSCP] "DSCP Value"="46" "Local Port"="40000:50000" "Application Name"="CiscoCollabHost.exe" "Local IP"="*" "Local IP Prefix Length"="*" "Protocol"="*" "Remote IP"="*" "Remote IP Prefix Length"="*" "Remote Port"="*" "Throttle Rate"="-1" "Version"="1.0" [HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\QoS\WebexAppVideoDSCP] "DSCP Value"="34" "Local Port"="40000:50000" "Application Name"="CiscoCollabHost.exe" "Local IP"="*" "Local IP Prefix Length"="*" "Protocol"="*" "Remote IP"="*" "Remote IP Prefix Length"="*" "Remote Port"="*" "Throttle Rate"="-1" "Version"="1.0" Save file as WebexQos.reg and to import double click on the file.
