Genesys Cloud CX Utility supports WebRTC configuration as the phone endpoint for agents using the Salesforce integration to make and receive calls, with settings saved on a per-station basis for customized configuration management. The utility provides comprehensive audio device configuration options, allowing users to select microphone and speaker devices from available options, though speaker selection is not available in Firefox browsers. Advanced audio processing features include Automatic Mic Gain to control microphone volume levels with the option to disable if volume fluctuation occurs, Echo Cancellation to remove speaker feedback when using speakers, and Noise Suppression to reduce background noise. Users experiencing difficulty with noise separation may need to reposition the microphone closer to their mouth or speak louder. The Test Settings function enables verification of microphone connectivity, network connectivity, and network throughput, with a Restart Tests option available to validate settings after modifications. Common microphone issues can be addressed by checking physical connections, verifying computer volume settings, and selecting alternative microphones if multiple devices are connected. Connectivity problems may be resolved through VPN disconnection, switching to wired connections, or reviewing browser permissions and application conflicts. Additional troubleshooting guidance includes unmuting the microphone in omni-channel call controls, closing competing applications accessing the microphone, and enabling browser microphone permissions. For persistent connectivity issues, users should disconnect from VPN connections, switch from wireless to wired network connections, and reconnect calls as needed, with escalation to IT department support for unresolved problems.
