Key concepts

This is the restart of Call Automation Service. It is renamed to Call Automation service and being more intuitive to use.

CallAutomationClient provides the functionality to make call, answer/reject incoming call and redirect a call.

CallConnection provides the functionality to perform actions in an established call connection such as adding participants and terminate the call.

CallMedia introduces media related functionalities into the call.

CallRecording provides the functionality of recording the call.

CallAutomationEventParser provides the functionality to handle events from the ACS resource.


To be determined.


If you recieve a CommunicationErrorException with the messagae: "Action is invalid when call is not in Established state." This usually means the call has ended. This can occur if the participants all leave the call, or participants did not accept the call before the call timed out.

If you fail to start a call because of an HMAC validation error, be sure your access key is correct, and that you are passing in a valid conversation id.
