QuestionQ47

Media and QoS

End users report poor video quality and choppy voice on Cisco Collaboration endpoints. The engineer changed the users’ device pool but did not resolve the issue. What action should be taken to troubleshoot this problem?

  • A Restart the Cisco Location Bandwidth Manager service on the Cisco UCM publisher
  • B Check for duplex/speed mismatches between the network port settings of the system and network switch
  • C Use direct IP address calls between two endpoints to troubleshoot call quality issues
  • D Set the service parameter Use Video Bandwidth Pool for Immersive Video Calls to ג€falseג€
Explanation

A direct IP call between two endpoints isolates potential WAN or call-control infrastructure issues from the endpoint-to-endpoint media experience. Comparing its quality with a normally placed call helps determine whether the fault is in the endpoints/network path or in Cisco Unified Communications Manager and related infrastructure.
