Configuring QoS
MeetingBar A20 for Zoom Rooms is subject to the bandwidth and the delay. Therefore, the QoS is very
important for the network having limited bandwidth. QoS is a major issue in VoIP implementations,
regarding how to guarantee that packet traffic is not delayed or dropped due to interference from other
lower priority traffic. The endpoint supports the DiffServ model of QoS.
About this task
• Audio priority: the loss of audio packets, the delay and so on may cause poor audio quality. To solve
this, you can configure DSCP priority for the audio packets.
• Video priority: some issues, such as the video packet loss and delay may cause the video images
distorted and unclear. To ensure acceptable visual quality for video, video packets emanated from the
system should be configured with a high transmission priority.
• Video priority: to ensure better presentation, data packets (PC content) emanated from the system
should be configured with a high transmission priority. DSCPs for audio, video and data packets can be
specified respectively.
