Difference in ring tones.....Help..!d

We have tried to change our ring doorbell to a more christmassy one and so we have gone for the ‘Deck The Halls’ tone. However, despite that tone playing inside the house and on our phone alerts, when you stand outside and ring the bell you can only hear the ‘standard’ ring doorbell tone. If you chance the tone should it not change when you press the doorbell as well and so be audible to the person calling at your house…? Any help would be gratefully appreciated…!
