I want to use DTMF for customer not for assistant

@amityadavazm Certainly! DTMF (Dual-Tone Multi-Frequency) can be used for customer input during calls. This allows customers to interact with automated systems by pressing keys on their phone keypad. If you're looking to implement DTMF for customer interactions in your voice application, you'll need to ensure that your system can recognize and respond to these signals appropriately. If you need guidance on how to set this up or if you have any specific questions about integrating DTMF into your voice application, please let me know, and I'll be happy to assist you further!

I need help

@amityadavazm Of course, I'd be glad to help you with implementing DTMF for customer interactions in your voice application. Could you please provide me with more details about what you need assistance with? Are you looking for information on how to capture DTMF inputs, how to configure your voice application to handle DTMF, or something else? Let me know so I can provide you with the most relevant information or guidance.

I want to know on how to capture DTMF input given by customer for assistant

@amityadavazm Capturing DTMF inputs given by a customer for an assistant involves a few steps. Here's a general outline of how you can do it: 1. **Voice Platform Configuration**: Ensure that your voice platform or telephony service supports DTMF. Most modern systems do, but you'll need to check the documentation for your specific service. 2. **Prompt the User**: Your voice application should prompt the user to enter their selection using their phone's keypad. For example, "Press 1 for sales, press 2 for support..." 3. **Capture the Input**: When the user presses a key, the voice platform detects the DTMF tone and sends the corresponding digit to your application. 4. **Handle the Input**: Your application needs to be programmed to handle the received DTMF input and perform the appropriate action based on the user's selection. 5. **Continue the Interaction**: After processing the input, your application can continue the interaction with the user, either by providing information, routing the call, or asking for more input. If you're using a specific voice API or platform, they will likely have a method or event that gets triggered when a DTMF input is received. You would need to write a handler for this event to process the input. If you can tell me which voice platform or API you're using, I can provide more specific instructions or code examples.

I am using Twilio

@amityadavazm Great! Twilio has built-in support for capturing DTMF inputs. Here's how you can set it up: 1. **Gather Input**: Use Twilio's

<Gather>

verb in your TwiML (Twilio Markup Language) to collect DTMF inputs. This verb waits for the user to press keys on their phone and then sends the input to a specified URL as a POST or GET request. 2. **Specify Action URL**: Define the

action

attribute of the

<Gather>

verb to specify where Twilio should send the DTMF input data. 3. **Set a Timeout**: Optionally, you can set the

timeout

attribute to define how many seconds Twilio should wait for the user to start entering digits. 4. **Handle the Input**: Write a handler on your server at the action URL to process the POST or GET request containing the DTMF input. Here's a simple example of TwiML that uses the

<Gather>

verb:

xml
<Response>
  <Gather action="http://yourserver.com/process_input" method="POST" timeout="10" numDigits="1">
    <Say>Please enter your selection followed by the pound sign.</Say>
  </Gather>
  <!-- If customer doesn't input anything, redirect to another URL -->
  <Redirect>http://yourserver.com/no_input</Redirect>
</Response>

And here's an example of a simple handler in Node.js using Express:

javascript
const express = require('express');
const bodyParser = require('body-parser');
const app = express();

app.use(bodyParser.urlencoded({ extended: false }));

app.post('/process_input', (req, res) => {
  const digits = req.body.Digits;
  console.log(`User entered: ${digits}`);
  // Process the DTMF input (digits) here
  // ...
});

app.listen(3000, () => {
  console.log('Your app is listening on port 3000');
});

Make sure your server is publicly accessible by Twilio (you might use services like ngrok for local development) and replace

http://yourserver.com

with your actual server URL. If you need further assistance with setting up your Twilio application to handle DTMF inputs, please let me know!

Python code @Vapi

Did you look at the documentation?

@amityadavazm try similar to this

trigger the dtmf tool/function with <insert-your-input-parameter-here

with your prompt.

Hi how can I get the api endpoint at back of my assistant, I want to invoke different assistant based on input by customer

check this: https://docs.vapi.ai/server-url/events#retrieving-assistants

This does not help, The user input is coming from twilio gather verb(DMTF input) , based on the input I need to trigger specific asssitant I created inside Vapi

This is not something I am familiar witBasically you are saying when a person press 1 transfer to this assistant right?

Yeah you got it

If so then it has to do with prompting. The person touching the keys and etc I dont do so not sure. If VAPI does not suport it, Twillio most likely does and you need to go look at the docs.

Ok Can you help me if we have any endpoint for the agent I created in Vapi

I don't follow you. If you want to connect the assistant you would just do a transfer to the number (which is tied to the assistant)

If I do response.dial() Enough?

You need to look at the documentation for how trnasfers work. For VAPI and Twillio.

How to use Dial Keypad function in conversation flow, to transfer calls to different assistants? @Chowderr

I am not trying to be rude but have you read the docs? You don't need DTMF to trnasfer. There are many simple ways to do this - like in your prompt for an example.

I read it but I didnt getmch from it

Please stop spamming me. 1. I do not work VAPI 2. I have already provided an answer. 3. if you don't understand you might need to pay someone.

I am sorry to disturb you. Thanks for your help

you have to call a vapi associated number and then use the above it will solve your problem.

Anyone build voice assistant using Vapi to communicate with other voice assistant(support agent)

yeah people have done that.
