One common request is for audio announcements to play at precise times. Precise timing is not currently supported; however, you can get close using Campaigns.
Why Campaigns and not Intervals?
Audio intervals are calculated based on the time since the last announcement played. If you have all your announcements in the same campaign, this can cause small delays for each message to add up to large delays by the end of the day.
Instead, you should use Campaigns to schedule playback and reduce your audio interval. For example, if you have announcements you want to play every half-hour:
- Create campaigns for each half-hour interval.
- Add your announcements to them.
- Set the playback window long enough that you can be sure the announcement will play (5-10 minutes works well in most cases).
Then, set your audio interval to something long enough that your message won’t play multiple times during the campaign’s playback window. Your playback times will still not be precise, but they will be closer.
