Phone ID'd it as Medical Debt Collector. I did have a recent surgery with the health system they referenced, but I am not overdue on the bill and am on a payment plan with auto withdrawal. A robotic voice telling me to "please call about an important business matter" seems like a scam. Either they dial a thousand local numbers in hopes of finding a few who have a connection to one of our region's major health care systems, or they somehow know of the connection through browsing history. Do not plan on calling them back, if it is a legit situation, they can have a human call me.
