Ring Tones. so that students can interrupt over whatever is playing, and I can hear it as if it is my phone ringing

I need a loud ring tone feature, so that students can interrupt over whatever is playing, and I can hear it as if it is my phone ringing. The ring tone should function similar to the way a phone does, as exampled when my phone music goes low automatically, so that the ring is clearly heard. I should be able to select anyone and ring them without any mouse right click.

Thanks for your input! I like the idea of audio reactions… Can you explain a little how and when you would actually use that feature?
