IOG is used to collect files from different AXE10 nodes (e.g. LE). Charging Files (e.g. Toll Tickets) are collected for onward processing by a Mediation device. For Intelligent Call Routing an IN application can be used with AXE10.
The Digit Decoder Function can be used to build logic for LCR. However, if your Network is large LCR IN application makes sound sense.
