201-652-4361... I've also gotten several calls from this number. California. Nobody answers when I do.

Called my cell; no message left.  It's probably one of the usual suspects -- solar panels, credit card/student loan relief, the "IRS," vaginal mesh class action lawsuit payment...  These calls constantly come in like a bad radio playlist in rotation.

Before the number above was the following number: 11911072000338.
No message was left.

They called less than 10 minutes ago. I answered, but there was no reply from their side and they hung up.
I tried calling back, but the line was messed with and you could tell it got forwarded to another line. The second line spoke the "We're sorry, but the number you have dialed is not in service at the moment" message, so I hung up and called again. THIS time the busy phone line started beeping and that's the last I know.
