Creating several events and channels
You can set up as many events as you want.
Within each event, you can add as many channels as you want.
NOTE: Each event has one listener code. Each channel has one speaker code. 🤔
This means, one event has only one listener code but as many speaker codes as it has channels. Makes sense? 😀🙌
Re-using events: Keeping the same invite codes
In LiveVoice you can create as many events as you want. But you can also re-use the same event as often as you want. So, if you want the invite codes to stay the same, simply don't delete your event. You can even rename it while the invite codes will stay the same.
Your bookings do not affect the code, features or anything related to the event - it just changes the number of listeners than can join the event.
