Just a standard phone ringer tone, with a few custom ones for wife/close friends - but my phone is muted and on vibrate about 99.9% of the time. I get call notifications (also vibrate only) via my Garmin watch.
Most of my communications are via text messages anyway, and I don't answer phone calls from numbers that aren't in my contact list. If they leave a message and I need to talk to them, I'll call them back.
