I keep getting calls, too. No one speaks right away, so I assume it's a telemarketer and hang up

Got a call.  Answered but nobody there.  Then they hung up.

Called me but I didn't answer.  No VM left.

Claimed to be google updating my business registry. after a few minutes asking for updated address and hours of operation they demanded $359 to perform SEO (search engine optimization) services for my business. I then hung up. They misrepresented of themselves as "Google Business Listings" not an SEO business.

No message. But after registering a bunch of web domains recently I've been getting a lot of unsolicited calls from web related companies trying to get my business. Judging from the other comments about this number I imagine it's for the same reason.
