What exactly happens when a call is set up?

Hello!

As the topic says, I’m wondering what exactly happen when a call is set up!
I read in another thread that when I ask for a token it returns with the
address to erizo controller, but how is the communication after that?

thanks

Hi,

actually when you ask your server (and it asks to nuve) for a token it
includes the erizo controller ip address. With this information the web
client establishes a websocket connection with erizo controller (when you
call room.connect function).

Later, when you publish or subscribe to a stream the web client exchanges
the sdps messages through that websocket connection with erizo controller.
When the negotiation finishes the web client and erizo controller establish
a SRTP connection to make the media communication.

I hope this helps you.
