no idea who they are.

I'm getting repeated calls from this number for the last week or so.  I'd get the calls at 9 am every morning, but now I'm getting them multiple times a day, at different times (just got another 2 minutes ago).

Call display reads "Wyoming."  The message left has a lot of background noise, then a woman's voice saying "hello?" repeatedly.

I don't know anyone in Wyoming.  I don't do business with any companies from Wyoming.

getting call from this number I don't know anyone with this area code.
