Got the same message as a robocall. Pressed 2 as instructed to be removed from the list. Hope that works. They use the phrae, "Sone from your number requested information," to make it appear to the FCC, that it is a legitimate call. I have never requested information about a back or knee brace. I'm also reporting it to: https://consumercomplaints.fcc.gov/hc/en-us - Press the phone icon and you will be taken to the phone complain page. Can't post that link, as it issues a case number that will be unique to each person. You can also register as a user of the site and log in to see reports.
Identifies itself as "The Brace Hotline".
Medicare scam
CID shows "Med Clinic", to fool people into answering because they might think it is their doctor
