Quick Deploy

This template is the simplest possible Twilio Voice application: a Serverless Function that responds to any incoming call with a spoken "Hello World" message using TwiML's <Say> verb. It's a starting point for building voice applications — swap out the message or add TwiML verbs to gather input, record audio, connect to an agent, and more.

How it works

A caller dials your Twilio phone number
Twilio sends a webhook request to your Serverless Function
The Function returns TwiML instructing Twilio to say "Hello World"
The caller hears the message spoken aloud by Twilio's text-to-speech engine
