There is a world of difference in the feeling you get when leaving a voice message for someone who misses your call compared to actually speaking to them knowing they are listening to you. The next time you are in Salah (prayer) or you raise your hands in dua (supplication),

remember that Allah never misses your call and that you're not just leaving a message but that Allah is actually listening to you. The feeling you get knowing that Allah is listening to you is awesome and ensures added virtue (khushoo') to your Salah and dua.
