{{PEEvent
|Event=EventPartyAdded
|EventDesc=One or more parties has been added to the call as a result of a conference.

Voice MCS always distributes EventPartyAdded for every party. If only one party is added (as in the case of a simple conference call), the corresponding telephony object is specified in '''OtherDN'''. Similarly, if more than one party is added to a call and there are multiple EventPartyAdded messages, one for each party on the consultation call joining the main call, then the corresponding telephony object is specified in '''OtherDN'''.

The '''ThirdPartyDN''' and '''ThirdPartyDNRole''' attributes are not present if the switch does not distribute them to Voice Microservices.

|Event=EventPartyChanged
|EventDesc=The telephony object specified by '''OtherDN''' has replaced the telephony object specified by '''OtherDN''' in the previously received event; or the '''PreviousConnID''' of the call has been given a new value, '''ConnID'''.

The value of '''CallState''' can be either <tt>Transferred</tt> or <tt>Conferenced</tt>.

The '''OtherDN''', '''OtherDNRole''', '''OtherTrunk''', '''ThirdPartyDNRole''' attributes must not appear if the '''CallState''' is <tt>Conferenced</tt>.

The '''ThirdPartyDN''' attribute is not present if the switch does not distribute it to Voice Microservices.
|EventGroup=Call handling and transfer/conference

}}
{{PEEvent
|Event=EventPartyDeleted
|EventDesc=The telephony object specified by '''OtherDN''' has been deleted from the conference call in question.

The '''CallState''' attribute indicates whether a call is still considered as a conference (that is, the number of parties in the call is more than two).
|EventGroup=Call handling and transfer/conference
|OptionalAttrs=AgentID, ANI, CallHistory, CustomerID, DNIS, Extensions, NetworkCallID, NetworkNodeID, OtherDN, OtherDNRole, OtherQueue, OtherTrunk, Reasons, ReferenceID, ThirdPartyDN, ThirdPartyDNRole, ThisQueue, ThisTrunk, TransferredNetworkCallID, TransferredNetworkNodeID, UserData

{{PEEvent
|Event=EventQueued
|EventDesc=The call has been queued in the ACD group specified by '''ThisQueue'''.

The '''PreviousConnID''' attribute must be included if the value of '''CallType''' is <tt>Consult</tt>.

'''ThisDN''' and '''ThisQueue''' attributes must have equal values.
|EventGroup=Call handling and transfer/conference
|OptionalAttrs=AgentID, ANI, CallHistory, CallState, CollectedDigits, CustomerID, DNIS, Extensions, LastCollectedDigit, NetworkCallID, NetworkNodeID, OtherDN, OtherDNRole, OtherQueue, OtherTrunk, PreviousConnID, ThirdPartyDN, ThisTrunk, TransferredNetworkCallID, TransferredNetworkNodeID, UserData

}}
{{PEEvent
|Event=EventReleased
|EventDesc=The telephony object specified by '''ThisDN''' has disconnected or has been dropped from the call.

The '''OtherDN''', '''OtherDNRole''', '''OtherQueue''', and '''OtherTrunk''' attributes do not appear if the release is from a conference. In all other call scenarios, the attribute must be present only if such information is provided by a CTI link.

The '''PreviousConnID''' attribute must be included if the value of '''CallType''' is <tt>Consult</tt>.

The appearance of '''ThirdPartyDN''' depends on the following conditions:
*If information about the new destination is available from the switch at the moment when EventReleased is generated, then '''ThirdPartyDN''' is mandatory. Or, if Voice Microservices have initiated a single-step transfer, redirection, or previously set the forwarding target, this attribute is also mandatory.
*If a call has gone through a single-step transfer, been redirected, or forwarded by another application (not the Voice Microservices in question), the '''ThirdPartyDN''' attribute is absent.

{{PEEvent
|Event=EventRetrieved
|EventDesc=The call has been retrieved from hold.

In all call scenarios, the '''OtherDN''', '''OtherDNRole''', '''OtherQueue''', and '''OtherTrunk''' attributes must be present only if the information is provided by a CTI link.

The value for the '''ThisDNRole''' and '''ThisQueue''' attributes is the same as that for the events preceding EventRetrieved (EventEstablished and EventRinging) for the same call. For non-ACD calls, '''ThisQueue''' is not reported.
