Question

A developer is building an integration that must react in near real time whenever a new voicemail message arrives for a specific Webex Calling user. Rather than repeatedly polling the Webex REST API, the developer wants Webex to push notifications to an HTTPS endpoint. Which approach correctly meets this requirement?

Accepted Answer

Create a webhook subscribed to the appropriate resource and event, providing a targetUrl so Webex sends an HTTP POST when the event occurs

Answer

Configure a scheduled cron job that calls the messages resource every 30 seconds and diffs the results

Answer

Enable SNMP traps on the Webex Calling organization so voicemail events are forwarded to the endpoint

Answer

Open a persistent WebSocket to Control Hub and register for SIP NOTIFY messages from the calling backend
