So I have several CTX100 systems, CHSUB112A. I should purchase the winadmin software and manage them that way?

Is it easy to figure out? Things like changing button assignments on phones, to display names and creating new extensions. I would reach out to phone vendor to see about software but what would be the expected cost of the software, and is there are particular version that I should be using, or should it be compatible with all the CTX100 systems?

We also have 2 CIX40 systems, would the winadmin software work with those as well?

Thank you for your assistance!
