Yeastar meeting room display devices issues

I am looking for someone to troubleshoot the issues I am experiencing with my Yeastar meeting room display devices. The specific issue I am facing is that the devices are not showing in the active state.

I have not tried any troubleshooting steps myself as I am not familiar with troubleshooting such devices.

My preferred outcome after the troubleshooting is to have the devices showing in the active state.

- Expertise in troubleshooting Yeastar meeting room display devices
- Knowledge of how to resolve issues with devices not showing in the active state
