  15:  ✅ 1️⃣ Setup Phase

  16:      • peerConnectionFactory (First)

  17:      • signalingServerUrl (Set before initWebSocket)

  18:      • initWebSocket() (WebSocket must be ready before connection starts)

  19:  ✅ 2️⃣ Connection Setup

  20:      • peerConnection (Created AFTER WebSocket)

  21:      • dataChannel (Requires peerConnection)

  22:      • localAudioTrack (Requires peerConnectionFactory)

  23:      • localVideoTrack (Requires peerConnectionFactory)

  24:      • peerConnection.addStream(mediaStream);

  25:  ✅ 3️⃣ Signaling & Connection

  26:      • Send SDP Offer → peerConnection.setLocalDescription()

  27:      • Receive SDP Answer → peerConnection.setRemoteDescription()

  28:      • ICE Candidate Exchange → peerConnection.addIceCandidate()

  29:  ✅ 4️⃣ Data Transfer

  30:      • Wait for dataChannel.state == OPEN

  31:      • Send & Receive Messages

  32:  ✅ 5️⃣ Handle Disconnections

  33:      • WebSocket Reconnect

  34:      • ICE Restart on Disconnection
