+It is possible to pass `config` RTCConfiguration object in order to configure TURN server or other parameters.
+```ts
+config: {
+  iceServers: [{
+      urls: "stun:stun.services.mozilla.com",
+      username: "louis@mozilla.com", 
+      credential: "webrtcdemo"
+  }, {
+      urls: ["stun:stun.example.com", "stun:stun-1.example.com"]
+  }]
+}
+
+```
+
+You can pass `onAgentConnect` callback. It will be called when someone from OpenReplay UI connects to the current live session. It can return another function. In this case, returned callback will be called when the same agent connection gets closed.
+```ts
+onAgentConnect: () => {
+  console.log("Hello!")
+  const onAgentDisconnect = () => console.log("Bye!")
+  return onAgentDisconnect
+}
+
+```
+Warning: it is possible for the same agent to be connected/disconnected several times during one session due to a bad network. Several agents may connect simultaneously.
+
+
+A callback `onCallStart` will be fired when the end-user accepts the call. It can return another callback that will be called on call end.
+```ts
+onCallStart: () => {
+  console.log("Allo!")
+  const onCallEnd = () => console.log("short beeps...")
+  return onCallEnd
+}
