7/31/16 Update: Some audio experts are sharing their analysis and suggest this could be a hoax. I am not yet clear if that's the case, more to come though...!
A report has just been submitted to MUFON by a man who, a few years ago, received a very mysterious phone call. The call lasted long enough for him to get a 3:30-minute recording, which you can listen to an analysis of below.
I am Taiwanese live in Tokyo kitaku

This is probably just a case of interference, but the fact that the phone rang before makes it extra spooky.
