What is Auto Outbound Call?

Auto Outbound Call is an automated testing feature where Cekura automatically initiates outbound calls when you run evaluators. Unlike manual outbound testing where you write scripts to handle calls, this feature does everything automatically.

​
How It Works

1

Enable Auto Outbound

Toggle the Auto Outbound Call setting ON in your agent settings
2

Run Evaluators

Execute evaluators through the dashboard - no script needed
3

System Calls Automatically

Cekura uses your voice provider (Vapi, Retell, or ElevenLabs) to initiate calls
4

Review Results

Check test results and transcripts in your dashboard

​
Prerequisites

  • Outbound mode enabled: Agent’s inbound must be set to false
  • Voice provider configured: Valid API key and Assistant ID for your provider (Vapi, Retell, or ElevenLabs)
  • Evaluators ready: Created evaluators with valid phone numbers

​
Enabling Auto Outbound Call

Navigate to your agent settings and toggle Auto Outbound Call to ON.
Enable Auto Outbound
Ensure your voice provider account has sufficient credits for making calls.

​
Advanced: Trigger URL Webhook

For advanced use cases, you can configure a Trigger URL to receive webhook notifications instead of automatic calls. This lets you add custom logic before the call is made.
Advanced Feature: When you configure a trigger URL, Cekura sends a webhook to your endpoint instead of automatically calling. You must handle the actual call initiation yourself.

​
When to Use

Use trigger URLs when you need to:
  • Add validation or business logic before calls
  • Schedule calls for specific times
  • Integrate with internal systems
  • Log or audit call requests

​
How It Works

1

Add Trigger URL

In your agent settings, navigate to the Provider Data field (Vapi Data / Retell Data / ElevenLabs Data) and enter your webhook URL.
Configure Trigger URL in UI
2

Receive Webhook

When evaluators run, Cekura sends a POST request to your URL with call details
3

Make the Call

Your system processes the webhook and initiates the call using your provider’s API

​
Webhook Payload

Cekura sends the following JSON payload to your trigger URL: 
{
  "from_number": "+1234567890",
  "to_number": "+14159976447",
  "dynamic_variables": {
    "customer_name": "John Doe",
    "policy_number": "POL123456"
  }
}
Fields:
  • from_number: Your agent’s contact number (the number making the call)
  • to_number: The evaluator’s phone number (where to call)
  • dynamic_variables: Optional test profile data for dynamic prompting
Your webhook endpoint must be publicly accessible (HTTPS), return a 200 or 201 status code, and respond within 30 seconds.

​
Response Format

Your webhook should return: 
{
  "success": true,
  "call_id": "optional_provider_call_id"
}

​
Troubleshooting

Check that Auto Outbound Call is enabled, agent is in Outbound mode, and voice provider credentials are valid.
Verify trigger URL is publicly accessible (HTTPS), returns 200/201 status, and no firewall is blocking requests.

​
Best Practices

  • Monitor credits: Track your provider account balance
  • Valid numbers: Use correct phone number format (+1XXXXXXXXXX)
  • Secure webhooks: Use HTTPS, validate requests, implement rate limiting
