Hi Tobias,
This is a great suggestion. Looking at this view, it seems we only expose the "Participant Name" at the Queue dashboard level - instead of the ANI. I spoke with our support engineers, and they'd like to submit this as an enhancement request.
When you have a moment could you create a ticket with PureCloud Support? This will allow them to document the ticket as an enhancement request, so it can be evaluated further.
Hope the day is going well!
Joe
