Twilio Voice Integration in ASP.NET Application

Overview

This ASP.NET application demonstrates the integration of Twilio for handling voice calls. The application includes controllers for managing calls, a homepage, and generating Twilio access tokens.

Controllers

1. CallController.cs

   • Handles Twilio calls and connections.
   • Includes a method to connect to a specified phone number or a predefined support agent.

2. HomeController.cs

   • The default controller managing the main views of the application.

3. TokenController.cs

   • Generates Twilio access tokens with the necessary grants for voice capabilities.

Configuration

Ensure that your appsettings.json file includes the necessary Twilio configuration settings:

{
   "Logging": {
      "LogLevel": {
         "Default": "Information",
         "Microsoft.AspNetCore": "Warning"
      }
   },
   "TWIML_APP_SID": "your_twiml_app_sid",
   "TWILIO_ACCOUNT_SID": "your_twilio_account_sid",
   "TEST_TWILIO_ACCOUNT_SID": "your_test_twilio_account_sid",
   "TEST_TWILIO_AUTH_TOKEN": "your_test_twilio_auth_token",
   "TWILIO_API_KEY_SID": "your_twilio_api_key_sid",
   "TWILIO_API_KEY_SECRET": "your_twilio_api_key_secret",
   "TWILIO_PHONE_NO": "your_twilio_phone_number"
}

Client-Side Script: browser-calls.js

The script handles Twilio Client configuration and provides functions for initiating, answering, and ending calls.

Usage

1. Include the Twilio JavaScript library in your HTML file.
2. Ensure the server-side token generation endpoint is correctly configured.
3. Include the browser-calls.js script in your HTML file.
4. Call functions like callCustomer(phoneNumber), callSupport(), and hangUp() based on your application's logic.
