Quality of Service for Audio and Video Calls on VVX Phones
When the Quality of Service (QoS) setting is enabled on the Skype for Business server, VVX phones receive the Differentiated Services Code Point (DSCP) value from the server for Quality of Service (QoS) of audio calls placed or received from phones registered to the Skype for Business server.
Utilizing a Skype for Business server the value can be inbound provisioned via the Skype server. A partial backup looks like this:
The Skype for Business server does not provide in-band provisioning for DSCP for QoS of video calls for outbound video streams.
When video is enabled on VVX 501, VVX 601 or Trio phones, provision the phones to receive DSCP for QoS of audio calls using the above parameter qos.ip.rtp.dscp and for video calls using qos.ip.rtp.video.dscp.
