+When deploying in a cloud environment (like Hugging Face Spaces, EC2, etc), you need to set up a TURN server to relay the WebRTC traffic.
+The easiest way to do this is to use a service like Twilio.
+
+```python
+from twilio.rest import Client
+import os
+
+account_sid = os.environ.get("TWILIO_ACCOUNT_SID")
+auth_token = os.environ.get("TWILIO_AUTH_TOKEN")
+
+client = Client(account_sid, auth_token)
+
+token = client.tokens.create()
+
+rtc_configuration = {
+    "iceServers": token.ice_servers,
+    "iceTransportPolicy": "relay",
+}
+
+with gr.Blocks() as demo:
+    ...
+    rtc = WebRTC(rtc_configuration=rtc_configuration, ...)
+    ...
+```
