It's a scammer.  They call with a pre-recorded message saying you've won something.  The call is designed to sound like it's not pre-recorded.  They're using dragonspeak to filter your questions.  "Are you authorized to contact this number?" was met with a pre-recorded "I"m sorry, could you repeat that?"

They said a company name, and I don't remember what it was, but it doesn't matter.  The company name likely changes from call to call anyway, and there's no real company.

I doubt they get paid "per call" so much as they get paid per live phone number reached, which they add to a list to sell to other scammers.

I just hung up on it.
