Yes, unavailable - naturally, as HDS is the Historical Database Server, and there's no such thing as Realtime Detailed Tables, for instance Calls_Real_Time_Detail.
But to be quite honest, why would you ever need such information be available from an external application (if this is the reason you are asking). ANI is available in an ICM script. Skill group - well, not per call, but at least you can see how many calls are queued to a skill group. Duration - again, it depends on how you understand call duration.
Are you trying to build a super detailed wallboard with all the calling numbers, perhaps? ;-)
Well, if you want to go on the long road, the information you are looking for is actually available. You just need to tap into the resources available within the CTI or CTI OS server. As far as I know, the both send an unsolicited event message to the client if a call is queued or dequeued. The only thing you need to maintain is the list of calls in a separate database, and do some calculations. It should not be that difficult, after all.
Good luck with your project.
