Servers Required for All Configurations
Servers Required Based on Region
There are three different types of servers:
Hosts that are used in the authentication process.
Chalk Cloud Servers
Hosts that are used for session management, annotations, monitoring, and analytics.
In the context of signaling, these are not the connections that transport audio and video, but are used in establishing the audio/video connection.
Calls to these servers are made from the point that the app is launched , logging in, and starting the session.
