Twilio the world's leading cloud communications platform as a service (CPaaS) that enables you to develop SMS solutions, WhatsApp, Voice, Video, email, and even IoT. Twilio powers communications for more than 190,000 businesses, and enables nearly 932 billion human interactions every year.

In this course, we will leverage some of those capabilities to create a fully functional Call Center, where the users will log with their mobile number using SMS and call will be added to a dashboard in real-time, showing where each call stage is.

Calls will be greeted with a welcome message, and after adding to a queue, the workers on the call centre can track the call status on the dashboard the call will flow from ringing to queued to answered and of course in case we miss a call it will also display a call missed.

• Verify - We will use Twilio Verify to send a verification SMSto the user in the login faze, once the user is verified with Twilio we will create a JWTtoken that will allow the user to login to the Dashboard and subscribe to receive and make calls.

• Programmable Voice - We sill use Programmable Voice to make, receive, and monitor calls around the world and directly from the browser.

• Programmable SMS - We will use Programmable SMSto send and receive SMS using Twilio
