Hoping someone can help. I cannot find this information anywhere.

My phone displays in the window who is calling (sometimes a name, sometimes a number) before I pick it up. The phones in our other offices here do not. How do I get this same display to show on their phones? They can only see the name or number AFTER they've picked up the line... which doesn't work so well if you're trying to screen calls.

I thought maybe it was something we could get through our service provider, Comcast, but they said it must have something to do with the phone itself.

I've gone through the user's manual and have googled endlessly, but have not turned up anything useful or applicable to my situation.

Can anyone help? Thanks!
