No, I was referring to the Caller ID. Your KSU needs to be that rev. and the software needs to be that revesion or higher, just so you can run caller ID. On the phones, you will still use the 7000 series phones, there's also the 2000 series phones that are used on that system but there may be a software issue on that, I personally don't know and the books I have don't show it anywhere, hopefully somebody else will pop in on that one. sorry I can only give ya one out a two.
I'll make a call and see what I can find out about that and post my findings here.
