To set up the inbound call server URL in Vapi, follow these steps: ### Step-by-Step Guide: 1. Create an Assistant: - Start by creating an assistant in the Vapi Dashboard that will handle the inbound calls. Make sure to configure it with the necessary transcriber, model, and voice settings. 2. Get a Phone Number: - You can create a free phone number through Vapi or import an existing one (like from Twilio). This number will be used for inbound calls. 3. Set Up Server URL: - Create an Endpoint: Set up an endpoint on your server that Vapi can call to retrieve the assistant configuration and handle incoming call events. - Configuration in Dashboard: Go to the Vapi Dashboard and enter your server URL in the designated field on the account page. 4. Configure Inbound Call Handling: - Register the Server URL: You can set the server URL at different levels (account-wide, phone number, or assistant level). - Endpoint Testing: Use tools like ngrok to expose your local server for testing. 5. Testing and Debugging: - Simulate calls using tools like cURL to ensure your server processes incoming data correctly. 6. Call Your Number: - Finally, call your Vapi-configured phone number to test the inbound calling functionality. By following these steps, you can successfully set up the inbound call server URL in Vapi!

In the context of Vapi, hooks are mechanisms that allow developers to automatically execute specific actions upon certain events within the Vapi workflows. This feature enhances the functionality and interactivity of Vapi assistants by streamlining processes and automating responses to triggers. ### Key Points about Hooks: 1. Purpose and Functionality: - Hooks execute actions automatically when specific events occur, such as when a task starts or when confirmation is received. This reduces the need for manual intervention in routine events. 2. Availability: - Hooks are supported in both the

ApiRequest

and

Gather

workflow nodes, providing flexibility in operations without interrupting the workflow. 3. Example Configuration: - For instance, you can set up a hook for a call transfer:

json
   {
     "hooks": [{
       "on": "call.ending",
       "do": [{
         "type": "transfer",
         "destination": {
           // Your transfer configuration
         }
       }]
     }]
   }

In this example, when a call is ending, a transfer action is executed. 4. Conditional Execution: - Hooks can be conditionally executed using

Assistant.hooks.filter

, allowing different hooks to be triggered based on various outcomes, such as call completion or system errors. ### Benefits of Using Hooks: - Event Management: Hooks help manage events effectively, improving user experience by ensuring smooth transitions during interactions. - Transfer Actions: They enable seamless call transfers based on user input or call progress. - Enhanced Reliability: Hooks contribute to a more resilient and performant voice AI application by providing detailed control over workflows.
