I’m currently sending about 15 calls per minute from GoHighLevel into Vapi, but I’m consistently seeing 10–50% of them fail with the following errors: "message": "Over Concurrency Limit" and "error": "Rate limit exceeded". I’ve already purchased 3 concurrency add-ons in addition to the 10 concurrent calls included with Vapi, so my understanding is that the account should be able to handle up to 40 concurrent calls. i have a q and distributing 15 calls per min. and the average call is less than 20 sec. how come i am still hitting the concurrency limit? Could you please confirm if there’s an additional limit in place?

To handle excess calls and avoid concurrency errors, implement a call queue management endpoint in your server. Here’s a sample Express.js endpoint to manually trigger queue processing:

js
app.post('/process-queue', async (req, res) => {
  try {
    await processQueue();
    res.json({ message: 'Queue processing triggered' });
  } catch (error) {
    res.status(500).json({ error: 'Failed to process queue' });
  }
});

Set up this endpoint and call it when you notice calls are stuck in the queue—this helps ensure queued calls are processed as soon as capacity is available.

Hey, can you share the org_id? You can find it [here](https://dashboard.vapi.ai/org/settings). This will help me get more details about it.
