Enter your number and receive a call
When you start the phone call, the browser makes a request to Twilio and your server tells Twilio how to route the call to other browsers & devices, or out to the carrier network.
This call logic relies on a number of TwiML verbs including <Say> to speak audio to the caller and <Gather> to take dialpad input from the user. The browser connects to Twilio through WebRTC and then out to the carrier network.
