The caller ID said med clinic and as soon as I answer a pre-recorded message played stating that someone calling from my number had requested a back or knee brace. Was given two options, one to be put on the Do Not Call List, and two to talk to a representative. Even though I never made a call to this number that claims I requested a brace from them, I decided to stick it out and  attempt to talk to someone. I was put through to a woman, and I politely explained to her that I had never requested anything and was receiving this call perhaps by mistake. She didn't even acknowledge what I said, and instead hung up without saying anything. People who are this rude tend to be scammers in my experience. So in either case, it's either a solicitation or a scam. Don't talk to these people.
