Agent status export to txt file?

[ksytdy]

Hi guys!
I hope on your help so much!

I made a VBA script that switches AVAYA Supervisor agents' skills every 30 minutes according to a call center schedule stored in Excel table. But when the other agent in Excel table is on a call it is not possible to switch his skill as an error message is poped up by Supervisor process that changes skills; this process gets hung until you press OK on the pop-up window, which causes all the next agents' skills changes being impossible to be executed by the script as well.
Hence could you please advise if it's possible to export agent's call current status (available / on call / break) for example in *.txt file so that I can switch only those who are not on the call?

Thank you for any hint on the problem solution!
