Parlay X Call Notification over SIP/IMS allows third-party client applications retrieval of event information from the network. A third-party application can receive information about the call event through a notification registration.
A NotificationAdministrationSupport interface is also available. This operation issues a TerminateNotificationRequest message, which is designed to terminate notifications by removing the NOTIFICATION table entry. This is based on the results rendered from the TerminateNotifications request.
