My phone warned me that it was probably a scam so I didn't answer. It undoubtedly was. It had an interstate prefix, no caller ID, and cut out fairly quickly, indicating that the spammer's computer dialling system had found another victim and dropped my number.

Didn't answer, voicemail was left but it sounded like it was automated and it was in Chinese (Mandarin). I am not Chinese so not sure what it said.
