How Does Our Voice API Work?

The server will call your http(s) server using a POST command and will send JSON data containing information on a new incoming call, a newly setup outgoing call or a status update on a call (for example. done playing audio file). The Voice API will call your server to inform it on updates and ask for the next step(s) to perform.
