Setting up voice and video

Setting your device permissions

To join a meeting using your browser, Challo requires access to your microphones and cameras.

When you join a meeting for the first time, your browser prompts you because Challo wants to use your microphone and camera.

The way that your browser prompts you to ask for permission depends on the browser that you are using.

Typically, click Allow, to let Challo use your microphone and camera.
For example, on MacOS using Chrome browser, the prompt is displayed as follows:

If you do not see the prompt, or do not allow Challo to use your microphone and camera, you have to change your browser permissions.

Use the following table to change your camera and microphone permissions for the Challo website—https://app.cafex.com

After changing the permissions, you have to reload the meeting, so that Challo can request to use your microphone and camera again.

It is best practise to close other applications that may use your camera and microphone. These applications may prevent the browser, and Challo using the devices.

If Challo cannot use your microphone, you can join the meeting by phone.

Checking your device settings

Check your settings in the following ways:

  • On the check your settings dialog, before you click Join the meeting to enter a meeting
    • Click Settings to display the Your meeting settings panel
  • During a meeting, if you click SETTINGS

From the settings panel, you can change the following:

  • Select and verify your Camera
    • The preview area displays the camera input.
  • Select and verify your Microphone:
    • The sound meter below the microphone drop-down-box displays the audio input from the microphone you choose.
  • Select your Speakers:
    • Click TEST AUDIO to play a sound
    • To adjust the volume, use the Volume bar.
  • Toggle MICROPHONE to enable or disable your microphone before you join the meeting.
  • Toggle CAMERA to enable or disable your camera before you join the meeting.
  • Specify a Call me number and have Challo call your phone to join the meeting. See: Joining a meeting using Call me.

Important: If you plug in a microphone or camera device too soon, your browser may not detect the device. This means that the new device is not available on the Settings dialog. Reload the meeting to detect new devices appear.

Joining a meeting using Call me

Instead of using a browser for meeting audio, you can have Challo call your phone so that you can participate.

To have Challo call your phone to join a meeting:

  1. Open the meeting Settings
  2. Find Your meeting settings > Call me
  3. Provide a phone number to call in the following ways:
    • Enter a phone number
    • If you have set your phone number on your profile, you do not have to do anything else.
  4. Click Call me

If you join a meeting using a phone, you can still join the meeting using your browser, so that you can see the participants list, chat, and screen shares, for example.

If they check their Challo Settings, the headset is not found. Currently, they can use their Jabra headset, if they Change a site’s camera & microphone permissions for the Challo website http://app.cafex.com from ASK to ALLOW.
