Fix the setup before the call.
Use a focused test for your audio, connection, browser support, or camera before you make an internet call. Each tool explains what it measures and what it cannot verify.
Check audio before you call
Use the microphone test to see whether your browser receives sound and the speaker test to confirm that the selected output device is audible. Audio streams for these tests stay in the browser.
Check the connection that will carry the call
The speed test measures short download and upload transfers to Dadaphone. The stability test samples response time and response-time variation. Neither result guarantees end-to-end call quality.
Check browser and device support
The browser check reports whether the browser exposes key calling-related APIs. The camera preview is optional and helps verify a camera before a video appointment or screen-sharing session.
