Weird ringtone help

[XJ13sd]

So I hung up a call yesterday and put my phone in my pocket,1p4. All of a sudden my phone started saying. Ring..ring...ring ring ring in a strange robotic voice. Is this how face time connects? I'm just trying to figure out where this came from as it's not my ringtone nor do I have an app with this sound. The voice got louder and angrier sounding each time it said ring. Lasted about 6 seconds? Any ideas?

That is exactly the sound but how would my phone just start that noise? Never heard it before do not have it on my phone.

Figured it out. Thanks for the post checked YouTube on my phone and somehow it was on that specific video. Weird but thank you for restoring my sanity. Sort of right. Lol
