Activate Autoplay for Cloud PBX

In order to be able to play sound on the page without user interaction you must allow “autoplay” in the browser.  


Option 1: Automatic autoplay – Media Engagement Index (MEI)

The MEI measures an individual’s propensity to consume media on a site. Chrome’s current approach is a ratio of visits to significant media playback events per origin:

  • Consumption of the media (audio/video) must be greater than 7 seconds.

  • Audio must be present and unmuted.

  • Tab with video is active.

  • Size of the video (in px) must be greater than 200×140.

From that, Chrome calculates a media engagement score which is highest on sites where media is played on a regular basis. When it is high enough, media playback is allowed to autoplay on desktop only.
