That's exactly why I set a custom, selfrecorded ringtone as my on call ringtone. I had used a default one prior, but after a few small heart attacks, it was a no brainer.
I actually do this with my notification sound too, but never got around to making a ringtone.
Very few people call me to my personal, and I don't want to bother with the work phone since I'll just end up hating that sound no matter what it is.
Our on-call software apparently causes iphones to play the same sound as an earthquake alert here in Japan. Coworkers have had some literal ptsd-like experi nces and gotten shocked reactions when it goes off in public (at least by default, the sound is on).
On Android I just get some piddly 'ding' I have to set to retrigger as it won't even wake me up.
I hate every song I've used as a ringtone except my current one, which has been the helldivers theme since basically the launch of the game. It's just too damn good.
