My pet parrot mimics my phone's ringtone perfectly—and now my calls get ignored

I recently noticed that my African Grey parrot has learned to mimic the ringtone on my phone almost exactly. It’s so spot-on that when someone calls, my parrot starts repeating the ringtone right next to me. While it’s hilarious, it’s also causing a bit of a problem: people think their call is going unanswered because they hear the ringtone but then no one picks up right away. I’ve tried changing the ringtone to something less catchy, but he just learned that one too. I want to keep the bird happy without missing important calls. Has anyone else dealt with a pet that imitates sounds a little too well? What creative ways have you managed to keep your phone calls from getting ignored because of it?
