What about more listeners then expected?
To be prepared for unexpected additional listeners you can activate the "Temporary Auto Upgrade" option in you account settings.
How the Temporary Auto Upgrade option works
When the „Max Listener“ limit of your plan has been exceeded on a given day, LiveVoice automatically books an additional day plan (starting with the smallest day plan at 7€). That way, even if your pre-booked plan limit has been reached, more people can join, up to the auto upgrade limit you've set.Start with LiveVoice for free
