Instructions on how to test your camera and microphone before your discussions.  All participants need to allow camera & microphone access in the interactive meeting room

You can do a pre-call test to ensure your camera and microphone are working and that your connection is serviceable via our video API's test site.

*Note - Interviews that are audio-only, only require a working microphone.



  1. Navigate to: https://tokbox.com/developer/tools/precall/
  2. Click on Run Test
  3. Allow the test to check your audio and video quality and stability. The test will make recommendations to troubleshoot or improve based on the results. 
  4. If your video is working and you have selected your correct device, you will see yourself in the Video results screen. (only applies if required for the session)
  5. If your audio is working and you have selected your correct device, you will see a green indicator in the Audio results when you are speaking.mceclip0.pngmceclip1.png
  6. If your connection to our API servers is serviceable, you will see all green checkmarks under Connectivity to OpenTok Servers



7. If your connection is not serviceable you will see a message regarding the expected call quality



If you did not pass this test, try these troubleshooting options and redo the test:

  • Enabling access to your devices
    • Restart your computer and access the link again.
    • Completely close any other browsers or programs that may also be accessing the camera and microphone like Skype, Zoom, and Teams. If another program is open that is using your camera, the browser won't allow access to our site.
    • Record your video with wired headphones/earbuds with a microphone or use your computer mic -- remove Bluetooth headphones.
    • At the top of your browser in the address bar, you should find a webcam or a lock symbol. Click there to allow and/or select your microphone and camera. This should allow our site access.
    • Open an Incognito window in Chrome or an InPrivate window in Firefox/Edge and COPY then PASTE the link into the new browser.
    • Try again on a different browser. Chrome and Firefox are free and easy to download. 
    • Refresh your page at any time.
    • If you are receiving a 404 error page, COPY then PASTE the link into the address bar rather than clicking on it from your email.
  • Improving your network speed
    • Remove any other devices on your wifi connection (phones, tablets, etc) to free up bandwidth.
    • Use a wired connection: If possible, connect your device to the internet via an Ethernet cable. This can provide a more stable and faster connection compared to Wi-Fi.
    • Close other applications and tabs: Having multiple applications and tabs open can slow down your device and reduce the available bandwidth for your video chat.
    • Limit background activity: If possible, avoid downloading large files, streaming videos, or performing other bandwidth-intensive activities while on a video chat.
    • Restart your router: Sometimes restarting your router can help to improve network speed and connectivity.
    • Reduce video quality: Consider lowering the video quality of your video chat, as higher quality requires more bandwidth.
