They called my cell.

Called business phone, I didn't answer, they didn't leave a message. Did some online research and they are a company out of Idaho, it was most likely an unsolicited sales call.

called in the afternoon. Picked up and they hung up

called left no message  blocked

Answered. The guy asked, "Hey, is the boss there?" I said "no, he's not, would you care to leave a message?" He said he'd call back later. So, yes...unsolicited sales call is my guess.
