I too received a bogus call from this number. They got my first name right but the last name was totally garbled. It was reminding me of a non existent doctor's appointment 3 days from now at 10:30 am. The kicker - Doc's name was not clear but it sure sounded like Dr No show. Don't get it.
This is an automated service used by at least one doctor (mine is located in Chapel Hill, North Carolina) that reminds you of upcoming appointments. If I don't answer the phone, it leaves a brief voicemail.
