31930: Stream - Media - Buffer Overflow

Twilio raises this warning when a Media Stream is sending call audio to your WebSocket server and the WebSocket upstream becomes congested. When restricted bandwidth prevents the stream from keeping up, Twilio discards audio.

• Your server or network path has an upstream bandwidth restriction that causes congestion while Twilio is streaming audio over WebSockets.
• Your Media Streams application cannot reliably accept the real-time audio that Twilio sends to your WebSocket server.
• Network controls between Twilio and your WebSocket server are not fully configured for secure WebSocket traffic on port 443.

• Verify network load and available upstream bandwidth on the server that handles the Media Stream.
• Confirm that your WebSocket endpoint can accept secure WebSocket connections from Twilio on port 443 from any public IP address.
• Review how your application handles incoming Media Streams messages so it can continue receiving Twilio's real-time audio.
• Validate the X-Twilio-Signature header on your Media Streams endpoint while you troubleshoot connectivity and network configuration.
