Event Notification Capabilities

Considerations
When monitoring is established for a VDN or ACD domain, ECS generates event
reports as calls arrive at the domain. ECS does not generate event reports for
calls that are already present (in progress) at ACD or VDN domains when the
Request Notification is received. The ECS will generate the Call Offered to
Domain Event Report only if the call is not already sending event reports over an
Event Notification association related to the entered domain. (This is true for all
cases, including the case of a call entering or reentering a VDN as a result of the
Vector Return Destination feature.) Also refer to user scenario 11 in Appendix A,
“Call Scenarios and Applications” for more information on VDN.
Starting with R5: if a call is already active at a trunk group when Notification is
requested on the trunk groups, and the ECS then receives charging information
for that call, then the ECS will generate a Charging Event Request. The Charging
Event Report is the
only
report provided by an Event Notification trunk group
association. The event notification for trunk groups with the ##### domain will
provide a Charging Event Report for all trunk groups. Only one Event Notification
association per system is allowed for the domain type trunk access code. Due to
the volatility in traffic volume, it is recommended that customers reserve a
separate ASAI link for any application that invokes the Advice of Charge (AOC)
feature.
NOTE:
Event Notification capability has evolved over time. Prior to G3V3, only one
Event Notification per ACD or VDN domain was allowed at any one time.
G3V3 increased the number of associations that can be simultaneously
active, to three per ACD or VDN domain. In R6r, the number of Event
Notification Associations that can be active at a time, has been increased to
six per ACD or VDN domain. In R6si, the number of Event Notification
Associations per ACD or VDN domain, is still three.
