I am calling through twlio outbound api. Is there a way to end the ongoing call?

@Hasan Yes, you can end an ongoing call initiated through Twilio's API by making an HTTP POST request to the call instance resource with the

Status

parameter set to

completed

. This will terminate the call. If you need assistance with the specific API call or parameters, please let me know, and I'll be happy to guide you through the process.

@User @User

you can either use end call function or twiml to end the call.

Where is the end call function @Shubham Bajaj

go to vapi dashboard and advance section after that enable the end call function.

You are talking about https://docs.vapi.ai/assistants/function-calling#end-call right? Well this will happen when assistant decides ending the call. I want end the call myself.

checkout twiml hangup.

@Vapi can you share code for twiml hangup for ending vapi calls

@Hasan Certainly! To end a VAPI call using TwiML's

<Hangup>

verb, you would use the following TwiML response:

xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Hangup/>
</Response>

When the VAPI processes this TwiML response, it will end the ongoing call. You can provide this TwiML as a response from your web application when the VAPI makes a webhook request to your server. If you need further assistance on how to set this up in your application, please let me know!

@Vapi yes please

@Hasan Great! To use the

<Hangup>

verb in TwiML to end a VAPI call, you'll need to set up a web application that can respond to Twilio's webhook requests with the appropriate TwiML. Here's a simple example using Node.js and the Express framework: 1. First, make sure you have Node.js and npm installed. 2. Install the Express framework by running

npm install express

. 3. Create a file named

index.js

and add the following code:

javascript
const express = require('express');
const app = express();
const port = 3000;

app.post('/endCall', (req, res) => {
  const twiml = `
    <?xml version="1.0" encoding="UTF-8"?>
    <Response>
        <Hangup/>
    </Response>
  `;

  res.type('text/xml');
  res.send(twiml);
});

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`);
});

4. Run your application with

node index.js

. 5. Your application will now listen on port 3000 for POST requests to

/endCall

. To use this with Twilio, you'll need to: 1. Deploy your application to a public server or use a tunneling service like ngrok to expose your local server. 2. Configure your Twilio number's voice webhook URL to point to your server's

/endCall

endpoint. When a call is in progress, Twilio will make a webhook request to the

/endCall

endpoint, and your application will respond with the TwiML to hang up the call. Please replace the placeholder code with your actual server details and ensure that your server is properly secured. If you have any questions or need further assistance, feel free to ask!

@Vapi does injecting messages into call support hangup

@Hasan Injecting messages into a call typically refers to sending audio messages or playing text-to-speech during an ongoing call. This action itself does not inherently include the functionality to hang up the call. However, you can sequence your call flow to play an injected message and then hang up the call immediately after. For instance, in Twilio's TwiML, you might use the

<Say>

verb to inject a message and then use the

<Hangup>

verb to end the call:

xml
<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Say>Thank you for calling. Goodbye!</Say>
    <Hangup/>
</Response>

In the above TwiML, the call will play the message "Thank you for calling. Goodbye!" to the caller, and then it will hang up the call. If you are referring to a specific feature or function within VAPI that allows for message injection and are wondering if it supports a hangup action, please provide more details or refer to the VAPI documentation for that feature. If it's not clear from the documentation whether hangup is supported, you might need to ask support for more info on this.

@Vapi provide code for injecting this through vapi api

@Hasan To inject a message and then hang up the call using VAPI, you would typically use the VAPI's methods to create a sequence of actions. However, as of my knowledge cutoff in April 2023, VAPI does not have a direct method for injecting messages into a call like Twilio's TwiML

<Say>

verb. If VAPI has been updated to include such functionality, you would need to refer to the updated VAPI documentation for the specific method to use. The code would generally involve calling a method on the Vapi instance that you have created, passing in the necessary parameters to play your message, and then another method to hang up the call. Since I don't have the updated information on VAPI's capabilities beyond April 2023, I recommend checking the latest VAPI documentation or contacting VAPI support for the most accurate and current method to achieve this. If VAPI does not support this functionality, you would need to use another service that provides call control APIs, such as Twilio, to inject messages and hang up calls programmatically.

i don't have the code but yeah try googling you will find for sure.
