Highly suspicious call. I sent the call to voicemail as I was in a meeting, and listened to the voicemail when my meeting ended.
Voicemail started with hold music, then switched to what sounded like a recording of a woman's voice speaking what I /think/ was Chinese. I believe it was a recording because it had that artificial polish to it like a newsreader or a train station announcement. I couldn't tell you what she was saying. The whole thing seemed off. Did not attempt to call back.
