Note: The Unringing event is available only with X11 Release 19 and
later software. X11 International Phase 7 software offers only four
status change events.
¥ Transfer completed to notifies the application when a DN has
completed a transfer to another DN. This message is sent on behalf of
the destination DN of the transfer, the party which had just received the
transferred call. This message is supported for both analog and digital
sets.
¥ Conference completed to notifies the application when a DN has
completed a conference to another DN. This message is sent on behalf
of the destination DN of the conference, the party which is being

¥ Conference Initiation notifies the application when a conference is
initiated by or on behalf of a set. Conference initiation is supported for
