When end users report bad video quality and voice choppiness on Cisco Collaboration endpoints, it indicates that there may be an issue with the network or configuration settings. In this scenario, changing the device pool the users were in did not correct the problem. Therefore, further troubleshooting steps are required to identify the root cause of the issue.
Option A suggests restarting the Cisco Location Bandwidth Manager service on the Cisco UCM publisher. This service manages the location and bandwidth settings for the devices in the system. While restarting this service may resolve the issue, it is not necessarily the best approach to take as it is a blanket solution that may not address the root cause of the problem.
Option B suggests checking for duplex/speed mismatches between the network port settings of the system and network switch. This option is a good approach to take as it checks for configuration issues that can affect network performance. Duplex/speed mismatches can cause network congestion and lead to bad call quality.
Option C suggests using direct IP address calls between two endpoints to troubleshoot call quality issues. This option is also a good approach to take as it eliminates the network from the equation and can help identify if the issue is with the network or the endpoints.
Option D suggests setting the service parameter Use Video Bandwidth Pool for Immersive Video Calls to false. This service parameter is used to allocate bandwidth for immersive video calls. Disabling it can free up bandwidth, but it may not address the root cause of the problem.
In conclusion, the best approach to troubleshoot the issue is to check for duplex/speed mismatches between the network port settings of the system and network switch and use direct IP address calls between two endpoints to isolate the problem. Restarting the Cisco Location Bandwidth Manager service and disabling the Use Video Bandwidth Pool for Immersive Video Calls service parameter may be used as secondary measures if the issue persists.
