+14151970485 called and left no message. Caller ID said V8111902430000081968 and gave no location. I don't think numbers can begin with a 1 so either 197-0485 was spoofed as a (415) number or it came from Switzerland, which has country code 41. I think spoofing is more likely.

I answered a call from +1 (415) 197-0485, no one was there
