Make a Call

This activity enables you to initiate an outbound voice call. It can be used to perform automated voice notifications, deliver pre-recorded or dynamic messages, and handle call status callbacks for further processing.

Properties

INPUT

Say: Specifies the text that should be read out during the call. If this property is provided, Twilio will convert the text into voice.
