For incoming calls to PCOL, the called number is the
default extension value (*****).
For incoming calls to a TEG (principal) group, the TEG
group extension is provided.
For incoming calls to a principal with bridges, the
principals extension is provided.
Connected
Party number
(alerting party
number)
For outgoing calls over PRI or non-PRI facilities  Ð the
default trunk value (#####)
For incoming calls Ð locally alerting extension (primary
extension for TEGs, PCOLs, bridging).  If the party
being alerted is on the switch, then the extension of the
party being alerted is passed.
Call_idThis switch-assigned call identifier is used to associate event
reports to calls and to identify a call the adjunct wants to
control.  The call identifier is unique within the switch.
Party_idThe switch-assigned identifier that uniquely identifies a party
on a call.  The switch provides the identifier and the adjunct
should retain it for future operations.  The party identifier is
unique within the call_id.
User to User
InformationIf UUI is stored with the call, then that UUI is included in the
Alerting Event Report.  This applies to UUI that originated in
an ISDN PRI/BRI SETUP message; in an ISDN
DISCONNECT message; or in an ASAI Route Select, 3rd
Party Make Call, or 3rd Party Auto-Dial message.
Reason for
RedirectionThe reason the call has been presented and is alerting at a
domain-controlled station.  Only applies to calls redirected by
the switch or by ASAI from the original destination.
NOTE:
This event report is not guaranteed for each call, such as an outbound call
that is not end-to-end ISDN, or in cases where you connect a party on an
existing call by bridging in or by using the pick up feature, for example.  In
both cases, the application would see the Connect Event Report without
seeing the Alert.

Call Conferenced Event Report
The Call Conferenced Event Report is sent under the following circumstances:
When an on-PBX station completes a conference by pressing the
``conference button on the voice terminal
When an on-PBX station completes a conference after having activated
the ``supervisor assist button on the voice set
When the on-PBX analog set user flashes the switch hook with one active
call and one call on conference and/or transfer hold
When an application processor successfully completes a Third Party
Merge request (conference option). The association over which the Third
Party Merge request was made receives an acknowledgement; no Call
Conferenced Event Report is sent over this association. All other
associations controlling or monitoring the resulting call, including any other
domain (station) control association(s) for the parties on the call, receive
the Call Conferenced Event Report.
When the ``call park feature is used in conjunction with the ``conference
button on the voice set
Report Items

extension, that extension is passed.
If the party being conferenced in is off the PBX, then a
default value of (#####) is passed.
NOTE:
There are scenarios in which the conference
operation joins multiple parties to a call.  In such
situations, the destination extension is the
extension for the last party to join the call.
Other Call_idThe call identifier that ended as a result of the two calls
merging
Resulting
Call_idThe call identifier retained by the switch after the two calls are

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 the switch cannot continue to send event reports for the call over an
Event Notification association because the call has been merged
(conferenced/transferred)
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.
Also, the Call Ended Event Report is sent only over Event Notification
associations; it is never sent over Call Control or Domain (Station) Control
associations.
Report Items
The following is a list of items provided with this report:
Call_idThe switch-assigned call identifier of the call that ended
CauseContains the reason for the call ending:
Normal clearing (CS0/16)
Call with requested identity has been terminated

The Call Initiated Event Report is sent by the switch to an adjunct that has a
Domain Control association for a station under the following circumstances:
When that station begins to receive dial tone
When that station is forced off-hook because another ASAI association
has requested a Third Party Make Call or a Third Party Auto Dial
capability for the station.  The switch does not send this event report to
the requesting association if that association receives an
acknowledgement (ACK) for the Third Party Auto-Dial request.
Report Items
The following is a list of items provided with this report:
Call_idThis switch-assigned call identifier is used to associate event
reports to calls and identify a call the adjunct wants to control.
The call identifier is unique within the switch.
Party_idThe switch-assigned identifier that uniquely identifies a party
on a call.  The switch provides the identifier and the adjunct
should retain it for future operations.  The party identifier is
unique within the call_id.

Call Offered to Domain Event Report
The Call Offered to Domain Event Report is generated when a call enters a
domain (VDN or ACD Split) for which event reporting has been requested by the
adjunct.  This event only applies to event notification associations.
Call Offered to a VDN Domain:
The event is sent when a call enters a VDN domain that has notification active.
From this point onward, call events for the call are reported.
If a call passes through several VDNs with notification active, then a Call Offered
to Domain Event Report is generated for each such VDN over their respective
monitoring association.
For G3V3 and later, a maximum of three notification associations can get events
for a call.  All associations receive the same events and event contents for calls
entering the domain when the notifications are active.
Call Offered to an ACD Split Domain:
This event report is generated when a call enters an ACD split domain for which
event reporting has been requested by the adjunct.
This report is sent even if the ACD split is in night service or has call forwarding
active.
If a call passes through several ACD split domains with notification active, then a
Call Offered to Domain Event Report is generated for each such ACD split
domain over their respective monitoring associations.
Report Items
The following is a list of items provided with this report:
Calling Party
Number/Billing
Number
(CPN/BN)
For incoming calls over PRI facilities Ð ``calling
number as in the ISDN SETUP message
For incoming calls over non-PRI facilities, the calling
party number is generally 
not provided.  In this case,
the Trunk Group number is provided instead.
For calls originated at a bridged call appearance Ð the
principals extension
For incoming DCS calls, if the DCS calling party
information is available to the switch (if a station with a
display gets it), this information is also made available
to ASAI.  Otherwise, the calling party information is
provided as the default.
