Not the “123” Icon. But to get the numbers to popup once you have created an Activity use edit and press Key Favourites then Add Normal Keys, select the Arris as device, highlight the number keys (can’t remember if they have to be done one by one or multiple can be selected) and then from memory I think you need to save. Now when you press the button at the bottom left the numbers (and any other keys you selected) will appear. If the order is wrong, again from memory, in edit mode press and hold till they become selected then slide them up or down.
