Event Reporting and U-Abort Capabilities

Call Ended Event Report

The Call Ended Event Report applies to Event Notification associations only and is generated under the following circumstances:

When the last party on a call drops

When ECS cannot continue to send event reports for the call over an Event Notification association because the call has been merged (conferenced/transferred)

NOTE:

To repeat, the Call Ended Event Report is only sent over Event Notification associations. It is never sent over Call Control or Domain (Station) Control associations.

NOTE:

The Call Ended Event Report should not be confused with the Third Party Call Ended capability provided by the Call Control Capability group. The Call Ended Event Report and the Call Ended capability carry the same information. They differ in that the former allows the Event Notification association to continue and the latter terminates a Call Control association.
