An optional feature, Unsolicited Status Events are provided in status change
messages, allowing 12 types of unsolicited status events to be sent to a host
application. The types of status change events are as follows:
¥ Ringing indicates that an incoming call is ringing on a DN. The status
change message contains the DNs of both the calling (where available)
and called parties.
¥ Answered indicates that a party has established a connection to another
party. The status change message contains the DNs of both parties
(where available).
¥ Off-hook indicates that a telephone is busy while it places a call or
answers an incoming call. The status change message contains the DN
of the telephone that is unavailable, and, if applicable, the far end DN.
¥ On-hook indicates that a telephone is available. The status change
message contains the DN of the telephone that is available and, if
applicable, the far end DN.
¥ Disconnected indicates that a telephone set has disconnected from a
call. The StatusChange disconnect message is enhanced for specific
scenarios. The Call Type IE is added to this message to indicate when a
set is disconnecting due to a complete transfer. The Call Type IE will
have a new value, H.A. - transfer complete, in the StatusChange
disconnect message. This value is passed to the application.
Note: The Disconnected event is available only with X11 Release 17
and later software. X11 International Phase 7 software offers only four
status change events.
¥ Unringing indicates when a set stops ringing without having answered
a call. Situations that would trigger a Status Change message with the
unringing status include a caller that abandons after listening to the
ringing tone; a call forwarded to another DN after having rung a
specified number of times (Call Forward No Answer); Call Pickup (call
is picked up by another party); or if an attendant goes off night service
while the night service DN is in a ringing state.
