When creating Notify workflow activities, you can use event-handler functions to respond to events from a telephony provider.

Not all activities or telephony providers support all events. For example, the Reject activity ends the call before the caller connects so the onNoAnswer function is never invoked from this activity.
Note: When configuring an activity to respond to an event, ensure that your telephony provider supports that event.
The following table describes available event handlers and lists the Notify workflow activities that can invoke each handler.
