WebRTC Application Setup

Your browser app needs a backend to tell Vobiz how to handle calls.

1. Log in to the Vobiz Console.
2. Navigate to Voice > Applications.
3. Click Create New Application.
4. Enter a Name (e.g., "WebRTC Demo").
5. Answer URL: This is the most critical part. It points to your backend server that returns Vobiz XML.
   • If running the demo server locally, this would be your public server URL.
   • Example logic for the Answer URL:

// The server receives a request with a 'To' parameter
// and returns XML to bridge the call.

vobiz_xml = `
<Response>
    <Dial callerId="${YOUR_VERIFIED_NUMBER}">
        <Number>${destination_number}</Number>
    </Dial>
</Response>
`;

6. Event URL (Optional): URL to receive call status updates (ringing, answered, hung up).
7. Click Save.

You must link a phone number to your application so it can receive calls.

1. Stay on the Application page (or edit your application).
2. Look for the "Phone Numbers" section or dropdown.
3. Select a purchased phone number to link it to this application.
4. Click Save.

   Now, any call to this number will be handled by your Answer URL.

An Endpoint acts as the user (the "phone") in the browser.

1. Go to Voice > Endpoints.
2. Click Create Endpoint.
3. Username: Create a unique username (e.g., agent001).
4. Password: Create a strict password.
5. Assign Application: Select the "WebRTC Demo" application you created in Step 1.

   This links your browser user to the specific backend logic.

6. Click Create.
7. Note down the Username and Password. You will use these to login from the browser SDK.
