Thanks for the info. I also received a call from 310 495 4617 on Nov 5. I blocked that number and they then tried calling back eight times (ha, ha but my phone never rang)! I have now blocked this number too (although my national scam blocker cut it off after the first ring).
It's an automated voice saying "Don't hang up"... It's about pain medication. Please report the caller to the FCC. Here is the link:
