Vonage Spoke Flow Designer Documentation

[gconway]

I am trying to implement Vonage voice API through the usage of Vonage Spoke developed by ServiceNow. My current problem is that there is no publicly available official documentation on how to use each action available in FlowDesigner for this spoke. For example, in what order they have to be used. Generate NCCO, Create outbound call.. etc. How to use the Event URL and Anwer URL to get/fetch each status of a call eg.: started, ringing, answered, busy, cancelled, unanswered, disconnected, rejected, failed , human/machine, timeout, completed, record, input, transfer. Could you please help? Thank you.
