Who called from 9175633274

no voice message left, don't know who calls....

Same. Random missed call. Didn't answer. No voicemail. I'm guessing just spam, though.

Received a call from this number on my direct line at work.  I didn't recognize the number so I didn't answer.  The caller left no message. Out of curiosity, I called the number back and a recording came on saying the number you have reached is not in service.

I had the same experience.

Random call on mobile, no voicemail, presumed spam
