Question What type of phone made this unique sound?

[todd1981]

I'm trying to identify the type of unique phone made the sound in the link below. I'm not sure if the sound is a startup, shutdown, message or ring. I have called this a human computing experiment as there is no software or search capability that would give me the answer. If you know what it is, please post an answer.

Is this a potential question for a trivia night? What does the YouTube creator say it is?

Maybe. However I can not find any type of search that identifies sounds and
Shazam only does music.

$100 reward is up for grabs. One person that can provide proof of what phone made the sound is the winner.
