Callsound never ends

When a user call an IPhone on discord, It’s doesn’t automatically discard after a while. It just keeps calling and calling. When you are outside leaving your phone behind, this can be annoying. Discord should change so after 1 Min the ringtone ends. This is good to save battery and to be more sustainable. Less battery drained= Less electricity use= less production if you know what I mean. Especially in a country which the leading Enegy source is Fossil fuels.
