Answer confirmation settings - Vobiz

Use confirmSound to provide audio instructions after a B-leg answers. You can configure confirmKey with the digit mentioned in those instructions.

confirmKey enforcement is currently unverified. Do not rely on it as a security, human-verification, or connection-acceptance gate until Vobiz confirms the behavior.

Vobiz requests the confirmSound URL using the POST HTTP method for a valid Play, Speak, or a Wait XML element. To play a message asking the recipient to input a DTMF tone to connect the call, return the second XML example.

Example

Response

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial confirmSound="https://your-domain.com/confirm_sound/" confirmKey="5">
        <Number>12025551111</Number>
        <Number>12025552222</Number>
        <Number>12025553333</Number>
    </Dial>
</Response>

This example configures 5 as the confirmation digit. It does not guarantee that Vobiz will withhold the connection when the recipient does not press it. Return the following XML to play a message:

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Speak>Enter the digit 5 to connect the call</Speak>
</Response>
