xmlCopy code<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Say>Thank you for calling Opentact.</Say>
    <Record />
    
    <!-- <Gather numDigits="2" attempts="2" timeout="10000" finishOnKey="*" callback="https://webhook.site/8b27856b-b16b-4933-8be2-befcd24932f6"/> -->
    
    <Gather numDigits="1" attempts="2" timeout="10000" finishOnKey="*">
        <Say>Now please enter 1 for man, 2 for woman.</Say>
        
        <Switch>
            <Case dtmf="1">

                <Callback url="https://webhook.site/8b27856b-b16b-4933-8be2-befcd24932f6"/>
            </Case>

                <Dial>
                    <Sip>[email protected]:9000</Sip>
                </Dial>
            </Case>
            
            <Default>
                <Say>Hi, nobody</Say>
                <Callback method="post" url="https://webhook.site/8b27856b-b16b-4933-8be2-befcd24932f6" />
            </Default>
            
            <Error>
                <Say>No DTMF code entered.</Say>
            </Error>
        </Switch>
    </Gather>
    
    <Hangup />
    <!--  <Redirect>${url}</Redirect>-->
    <!--  <Reject />-->
</Response>

Explanation:

• The call begins with a greeting, thanking the caller for reaching Opentact.

• A recording feature is initiated, allowing the system to capture any relevant information.

• A <Gather> block is employed to collect DTMF input. In this case, the caller is prompted to enter '1' for a man or '2' for a woman.

• A <Switch> statement evaluates the entered DTMF code and directs the call accordingly:

  • If '1' is pressed, Opentact responds with "Hi, man" and triggers a callback to a specified webhook.

  • If '2' is pressed, Opentact responds with "Hi, woman" and initiates a SIP call to the specified SIP address.

  • If neither '1' nor '2' is entered, Opentact responds with "Hi, nobody" and sends a callback with a POST request to a webhook.

• An <Error> block handles cases where no DTMF code is entered, providing appropriate feedback.

• The call concludes with a <Hangup> command.

Feel free to interact with the IVR by entering the specified DTMF codes and observing the corresponding actions.
