Call Scenarios and Applications
A-76 Issue 7 March 1998
14. User Scenarios - Information
Identifier (II) Digits
The first scenario shows an incoming ISDN/PRI call that includes CPN/BN (and
II-Digits) in the SETUP message. A Call Offered Event report is generated when
the call is offered to a split (the split has event notification). The call queues at the
split (Queued Event Report) until a agent becomes available. At that point the call
alerts at the agent (Alerting Event Report) and is answered (Connect Event
Report). Finally, the caller drops (Drop Event Report). The Call Offered, Alerting
and Connect Event Reports include the II-Digits which were delivered in the
ISDN-PRI Call Setup message. The Queued and Drop Event Reports do not
include the II-Digits.
