Can I transfer midcall to a twilio workflow ?

Currently using Twilio for my call system, VAPI does answer some calls and we are getting the assistant with an api call to our server (assistant-request). But I want to implement a new flow where if the user wants we will transfer the call to another Twilio Workflow. Can this be possible ?. I was thinking about implementing tools for this but I don't know if it is possible to transfer the call to a twilio workflow

@alep Absolutely, transferring a call to another Twilio Workflow is possible and can be a great way to enhance your call flow. You can achieve this by using Twilio's call control features within your VAPI application. When you receive an
assistant-request
and determine that the call needs to be transferred, you can use Twilio's
<Redirect>
verb or the REST API to transfer the call to the specified Twilio Workflow. The Workflow SID (unique identifier for the Workflow) will be required to direct the call appropriately. Here's a high-level overview of the steps you would take: 1. Determine the point in the conversation when a transfer is requested. 2. Use the Twilio API to initiate the transfer by providing the Workflow SID. 3. The call is then handled by the specified Twilio Workflow according to its configuration. If you need to implement this functionality and require assistance with the specific API calls or setting up the tools, please let me know, and I can guide you through the process or direct you to the appropriate resources. If you're ready to proceed with the implementation and need to know the exact API endpoint or method to use, just ask, and I'll provide the details.
You can continue this conversation by mentioning me in the message.

@alep To redirect a call to another Twilio Workflow using the Twilio REST API, you'll need to update the live call resource with the new instructions. Here's a general outline of the steps you would take: 1. **Fetch the Call SID**: You need the unique identifier for the call you want to redirect, known as the Call SID. 2. **Make an API Request**: Use the Twilio REST API to update the call with a new URL that points to the Twilio Workflow. Here's a simplified example of how you might do this in code using Twilio's Node.js library:
Copy code
javascript
const twilio = require('twilio');
const client = new twilio('YOUR_TWILIO_ACCOUNT_SID', 'YOUR_TWILIO_AUTH_TOKEN');

client.calls(callSid)
      .update({ url: 'http://your-application.com/newTwiml' })
      .then(call => console.log(call.to));
In the above code, replace
'YOUR_TWILIO_ACCOUNT_SID'
and
'YOUR_TWILIO_AUTH_TOKEN'
with your actual Twilio credentials, and
callSid
with the SID of the call you're redirecting. The
url
parameter should be set to the endpoint that returns TwiML instructions for the Twilio Workflow. If you're having trouble with the REST API, make sure that: - You're using the correct Call SID. - The URL you're providing in the update is accessible and returns valid TwiML. - Your Twilio credentials are correct. - There are no network issues between your server and Twilio's API. If you've checked all of these and it's still not working, please provide more details about the issue you're encountering, such as any error messages or logs, so I can assist you further. If you need to keep any information confidential, please ensure you do not share sensitive details like your Twilio credentials.

@User It is not redirecting in live call. What I want is for vapi to answer and if the user wants to, live call transfer to a twilio workflow

Yes, it is possible to use server message phone-control. Basically, a message will be sent to your server and you need to respond back with how you want to tackle it.
