How to implement push to talk?

[denis-obukhov]

Hello! Could you suggest how to implement Walkie-Talkie functionality? When a speaker starts speaking a connection to the room is established. But listeners need some time to connect to listen to upon receiving a notification. Thus, they can miss the beginning. Every listener should be able to listen to the message from the very beginning regardless of the time needed to connect to the stream. Could you suggest how to implement this using LiveKit?
