Question On Billing During Idle Animation On Talks Real Time Endpoit

Hi,

Does anyone know how the billing works when connected to the talks realtime endpoint? Are you build for the whole time the WebRTC connection is running or specifically only when the Avatar is talking as opposed to playing the idle animation.

If it is the case that you are billing only while the avatar is talking then what granularity does it go down to and is there a minimum billing length?
