The message contains an invoke FIE with:
Operation Value = Event Report, 
an “alerting” event (Specific Event IE), 
a party_id (Party ID IE),

the ECS a PROGress message for a variety of reasons contained in a Progress 
Indicator (within the PROGress message). The ECS forwards the Progress 
Indicator to the adjunct in the...
