Suggestion: To help diagnose intermittent server message issues, add logging to your webhook endpoint to capture all incoming requests and their payloads. For example, in Node.js/Express:

js
app.post('/webhook', (req, res) => {
  console.log('Received webhook:', req.body);
  res.status(200).send('OK');
});

This will help you verify if messages are reaching your server and provide evidence for support if they are not. If the issue persists, share recent call IDs and note any configuration changes with Vapi support for further investigation ([source](https://discord.com/channels/1211482211119796234/1372358449761091584)).
