We recently tried deploying AC on Call on our network. After setting up the backend, the iPhone still would not connect. Spoke to a tech support person, who wanted to install some .exe files on the server. I said, "Let's slow down. Installing .exe's on the server makes me nervous..." He then asks what iOS we are running. I replied "version 6." He says, "Oh, AC on Call has difficulties with iOS 6." I read that as, "Don't bother trying to run AC on Call with iOS version 6."
You would think that "What version of iOS are you running?" would be the first question...
