Before contacting OTN Technical Support for webcasting assistance, review these system requirements to ensure your equipment, system, and network setup meet the requirements.

Please contact your local IT support:

  • If your system does not meet the minimum requirements or if you have trouble determining this.
  • If you need assistance with service issues outside of OTN-supported system requirements.

System Requirements

For the best experience, ensure your computer or mobile device meets these specifications.


  • Microsoft Windows 10
  • Microsoft Edge, Internet Explorer 11+, Firefox, or Chrome (see also Recommended Browsers)


Mobile Devices

  • Android phone or tablet (version 7+); iPhone or iPad (version 10+)
  • Minimum resolution of 320 x 460 pixels

Audio Equipment

OTN recommends that you listen to a webcast using headphones, which have the following advantages:

  • Offer listening privacy and can eliminate external noise.
  • Allow for higher volume levels and usually have a better sound quality than the speakers built into desktop computers and laptops.
  • The sound does not get blocked by objects on your desk and is closer to your ears than with external speakers.

If you do not have headphones, the next best option is external speakers.

Troubleshooting Common Issues

Resolving Audio Issues

If you can see the video but cannot hear sound, it could be a problem with your speakers or your volume controls.

  • Test the sound on your system by playing an audio file.
  • Check that your device’s volume controls are:
    • Not muted
    • Set to a proper volume
  • If you are using external speakers, check that they are:
    • Plugged in to the correct socket
    • Powered on
    • Set to a proper volume
  • Check that the webcast window’s volume controls are:
    • Not muted
    • Set to a proper volume

Resolving Video Issues

If you have a poor-quality video image, the issue might be your device or your internet connection.

  • Close all apps except those needed for the videoconference.
  • Test your internet connection using a third-party app such as speedsmart.net, fast.com, or speedtest.net.
  • Ensure that your device is not using “low power mode” and that your device battery is fully charged.
