Diagnosing Call Quality Issues with WebRTC Diagnostics

When using Contact via a browser calls are handled using WebRTC which is a technology that enables real-time communication between applications. To ensure your agents browser is ready to handle calls a WebRTC diagnostics tool is available in the portal.

The diagnostics tool is designed to help agents quickly identify and resolve common issues that may affect their ability to receive or make WebRTC calls. It checks their WebRTC authentication, browser performance, microphone access, and network connectivity to the Contact Centre’s WebRTC servers.

Run this test if:

  • An agent is unable to receive or make WebRTC calls in their browser
  • The call quality is poor, or calls fail to connect
  • You suspect microphone or permission problems
  • You been unable to resolve the issue after performing the recommended troubleshooting
  • Support asks you to download and share diagnostic results
