Configuring and Viewing Quality of Service

You can assign a Quality of Service (QoS) priority level to video and voice calls using either pre-configured system settings or by creating your own settings.

Quality of Service settings involve configuring the MCU to add a Quality of Service (QoS) DiffServ Code Point value in the IP header of outbound packets. Routers on the network that support QoS can give preferential treatment for bandwidth, latency and jitter to such coded packets and facilitate the efficient transmission of packets. You can set QoS parameters on the MCU for voice calls, video calls or both.

Procedure

  1. In the MSA interface, on the sidebar, click MCU (if not already selected).
  2. Click the Settings tab.
  3. Click Quality of Service.
  4. In the Quality of service support field, set the required DiffServ Code Point value for each media type by clicking one of the following radio buttons:
    • None—Select to disable Quality of Service support
    • Default—Select to assign the default DiffServ Code Point value for each media type. The default settings represent Cisco recommendations.
    • Custom—Select to assign your own DiffServ Code Point value for each media type.

    If you select Default, the system automatically enters Quality of Service settings. If you select Custom, follow the steps below.

  5. In the Voice Priority field of the Video Calls section, enter a whole number from 0 to 63 to set the DiffServ Code Point value of voice packets that the MCU sends out. The default value is 34.
  6. In the Video Priority field of the Video Calls section, enter a whole number from 0 to 63 to set the DiffServ Code Point value of video packets that the MCU sends out. The default value is 34.
  7. In the Voice Priority field of the Voice Calls section, enter a whole number from 0 to 63 to set the DiffServ Code Point value of voice packets that the MCU sends out. The default value is 46.
