Configure devices for status change host notification

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-hookindicates 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-hookindicates 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.
