I am looking for advice on what elements within Avaya should be used for defining "true" Talk Time. This is broken down into 3 areas:

1 - Time spent talking on an Inbound Call
2 - Time spent talking to another agent / dept whilst Inbound Call on hold
3 - Time spent talking to a customer on an Outbound call whilst in state of wrap (call is agent invoked rather than provided by Dialler)

Looking through Avaya dictionary my understanding of the three above are:

1 = I_ACDTIME
2 = I_ACDAUX_OUTTIME
3 = AUXOUTOFFTIME

However I suspect that there is some overlap happening here and my question is therefore are the correct elements being applied and if not what should I be using?

All help gratefully appreciated
