My store is just about to start it's remodel but we still use old style buttons and even a few phones still work. I am fine with going to this new button as long as the alert is something I can hear but don't want to mute. If it's like a unique ring tone I can mute it and then call over the walkie if I am with a guest. That said, I know our phone system is kind of useless, half the time the software does not auto login properly. Many times I get calls on electronics for other areas because I'm the only one who's logged on. This can turn ugly if buttons are handled the same way.
