This applet is used to send an SMS back to the caller for an incoming call. It works in two ways –
Static: Any fixed message added on the applet in simple text is sent as a transactional content to the caller. Eg:”Thank you for calling us! We have received your order”.
Dynamic: Adding an URL on this applet, Exotel shall make a GET call to this URL and the response returned has to be in plain text. This response will be sent back to the caller as a transactional SMS.
