A RingOut can be cancelled using an API call to the RingOut API endpoint using the DELETE method when the RingOut is InProgress.

• API Endpoint: v1.0/account/{accountId}/extension/{extensionId}/ringout/{ringoutId}

Deleting the RingOut is only available when the RingOut has been initiated and the call has not been connected. For example:

• If you initiate a RingOut and immediately call the DELETE RingOut API Endpoint, the call would get hangup as long as the RingOut between the two parties is not connected (first leg has not been established)
• If the first leg of the call has been initiated, then the DELETE API will not hangup the call.
